Question 1

Who composed the official anthem that was featured in the promotional video for the 2018 Mens Hockey World Cup?

Accepted Answer

Introduction / Context: The 2018 Mens Hockey World Cup held in Bhubaneswar in Odisha was promoted through an official anthem and a high energy video that aimed to build excitement for the tournament. Sports related general knowledge questions frequently test awareness of such cultural and promotional details, including theme songs, mascots, and venues. This question checks whether you know which well known Indian music composer created the anthem that was used in the prime promotional video for the event. Knowing the answer also helps you connect major sporting events in India with iconic artists from the Indian music industry. Given Data / Assumptions: The tournament in focus is the 2018 Mens Hockey World Cup. The question refers to the official anthem used in a widely promoted video. The options list four famous Indian film music composers. We assume the student is asked about the officially commissioned anthem, not any fan made song. Concept / Approach: To answer this question, you need factual recall about sports current affairs from 2018. Important tournaments often collaborate with well known artists to create a theme song. The 2018 Mens Hockey World Cup anthem, titled Jai Hind Jai India, was a collaboration between a celebrated Indian composer and a famous lyricist. By recalling which composer was associated with this project, you can select the correct option. If you do not remember directly, you might use elimination based on which composer is most commonly linked with large national or international events and patriotic themes. Step-by-Step Solution: Step 1: Recall that the 2018 Mens Hockey World Cup was hosted in Bhubaneswar, Odisha, and had a high profile promotional campaign. Step 2: Remember that an official anthem called Jai Hind Jai India was created specially for this tournament. Step 3: Connect this anthem with the famous composer who often works on national level projects and has an international reputation for film and stage music. Step 4: The composer for this anthem was A. R. Rahman, who worked with lyricist Gulzar for this song. Step 5: Among the options given, match this information to select A. R. Rahman as the correct answer. Verification / Alternative check: You can verify the answer by recalling news coverage from 2018, where videos and articles described how A. R. Rahman and actor Shah Rukh Khan appeared together in the promotional video for the Hockey World Cup anthem. Another way to cross check is to remember that Rahman is often chosen for national sports events, such as previous sports ceremonies and official theme songs, which makes his association with a world cup level tournament highly plausible. No similar large scale collaboration with the other listed composers is commonly linked to this particular event, which further confirms that A. R. Rahman is the correct choice. Why Other Options Are Wrong: Pritam Chakraborty: A successful film composer, but he was not associated with the 2018 Mens Hockey World Cup anthem project. Anu Malik: Known for many Bollywood soundtracks, but there was no major news of his involvement in this specific sports anthem. Bappi Lahiri: Famous for disco style music and film songs, but not linked with the official hockey world cup anthem. Common Pitfalls: Students sometimes confuse different sports tournaments and their respective songs, mixing up cricket, football, and hockey events. Another common error is to guess based only on which composer they like best instead of recalling factual information. Some may also assume that a younger or more currently trending composer handled the anthem. To avoid these mistakes, always connect the event, the year, and any distinctive collaboration details, such as the presence of well known film stars or lyricists in the promotional video, before deciding on an answer. Final Answer: The anthem for the prime promotional video of the 2018 Mens Hockey World Cup was composed by A. R. Rahman.

Question 2

Which country unveiled the first underground hotel in the world, opened in Shanghai in 2018?

Accepted Answer

Introduction / Context: Around 2018, news reports highlighted the opening of a highly unusual luxury hotel that was built mostly below ground level in a repurposed quarry. The project drew global attention as the first of its kind, often described as the first underground hotel in the world. General knowledge questions about such record breaking infrastructure projects are common in competitive exams, because they combine geography, tourism, and technological achievement in a single fact. This question checks whether you can link the project with the correct country. Given Data / Assumptions: The hotel is described as the first underground hotel in the world. It opened in a city named Shanghai in 2018. The options list Japan, Dubai, China, and Malaysia as possible countries. We assume the term underground hotel refers to the widely reported quarry hotel project that extends many floors below ground level. Concept / Approach: The key to the question is recognizing Shanghai as a city in China and remembering that the much publicised underground quarry hotel is located there. The hotel often appears in news as the InterContinental Shanghai Wonderland or the quarry hotel. Since the location is clearly connected with Shanghai, the task becomes a matter of matching Shanghai with its country. Basic world geography knowledge tells us that Shanghai is a major coastal city in China. Once this is recalled, the correct option becomes straightforward. Step-by-Step Solution: Step 1: Identify the landmark mentioned in the question. It refers to the first underground hotel in the world that opened in 2018. Step 2: Recall that this hotel was built in a converted quarry and is widely known as the InterContinental Shanghai Wonderland. Step 3: Note the city name Shanghai in the title, which is a clear clue. Step 4: Remember that Shanghai is one of the largest and most famous cities in China, not in Japan, Dubai, or Malaysia. Step 5: Match Shanghai with China and choose the option that names China as the country. Verification / Alternative check: As an additional check, you can recall that Dubai, while known for many record breaking buildings, is a city in the United Arab Emirates and is not in the options as a country by itself in a strict sense. Similarly, Japan and Malaysia have their own tourism projects but are not associated with the famous quarry hotel in Shanghai. Looking at news images of the hotel, you may recall that the articles clearly labeled the location as near Shanghai in China. This cross check with geographic knowledge strongly confirms China as the right answer. Why Other Options Are Wrong: Japan: Well known for advanced engineering, but no major news connected Japan with the first underground quarry hotel opened in Shanghai. Dubai: Famous for iconic skyscrapers and artificial islands, but the quarry hotel project was not built in Dubai. Malaysia: A popular tourist destination, yet there was no widely reported world first underground hotel opening there in 2018. Common Pitfalls: Students may see Dubai in the options and select it because of its reputation for unusual luxury buildings, without noting that the question clearly names Shanghai. Others might overlook the importance of the city clue and try to recall the project by memory alone. Some candidates confuse underground structures with underwater hotels or other experimental projects. To avoid such errors, focus on all parts of the question stem, especially place names, and relate them to basic geography before answering. Final Answer: The first underground hotel that opened in Shanghai in 2018 is located in China.

Question 3

Which film won the Best Film award at the 24th Kolkata International Film Festival held in 2018?

Accepted Answer

Introduction / Context: Film festivals are important cultural events and are often covered in current affairs sections of exams. The Kolkata International Film Festival is a major festival in India, and its awards, especially the Best Film award, are common facts asked in general knowledge questions. In 2018, the 24th edition of this festival recognised a particular international film as Best Film. This question checks whether you remember which film received that top award, linking knowledge of cinema with awareness of major cultural events. Given Data / Assumptions: The event is the 24th Kolkata International Film Festival in 2018. We are asked about the film that won the Best Film award at this festival. The options list four titles: The Third Wife, Beauty Pageants, Antony Firingee, and Abyakto. We assume Best Film refers to the main international competition award, not a retrospective screening or opening film. Concept / Approach: To answer the question, you need to recall specific current affairs about awards in the field of world cinema. The key is to connect the 2018 edition of the Kolkata International Film Festival with its official Best Film winner. The Vietnamese film The Third Wife, directed by Ash Mayfair, received strong critical attention and was widely reported as the Best Film at this edition of the festival. Recognising this title among the options allows you to select the correct answer confidently. Step-by-Step Solution: Step 1: Note that the question is about the 24th Kolkata International Film Festival held in 2018. Step 2: Recall that the festival gives the Royal Bengal Tiger award for Best Film in its main competition. Step 3: Remember that the film The Third Wife, a Vietnamese period drama, attracted significant attention and was reported as the Best Film award winner at KIFF 2018. Step 4: Scan the options and identify The Third Wife among the listed choices. Step 5: Choose The Third Wife as the correct answer because it matches the known Best Film winner for that year. Verification / Alternative check: You can cross check by recalling other uses of the titles given. Antony Firingee is an old Bengali film that was used as the opening film at the festival, not the Best Film winner. Abyakto and Beauty Pageants may have been screened or discussed, but they are not recorded as the main Best Film award recipients. News articles, festival summaries, and current affairs capsules for competitive exams all highlight The Third Wife as the film that won the top prize at the 2018 Kolkata International Film Festival, which confirms your choice. Why Other Options Are Wrong: Beauty Pageants: There is no widely reported information about a film by this title winning the main Best Film award at KIFF 2018. Antony Firingee: A famous Bengali classic associated with the festival as an opening film tribute, but it was not the 2018 Best Film winner. Abyakto: A film linked with the festival, yet it did not receive the primary Best Film award at the 2018 edition. Common Pitfalls: A common mistake is to confuse the opening film of a festival with the Best Film winner because both receive attention in news reports. Another pitfall is to pick a more familiar or older Bengali title like Antony Firingee simply because it sounds familiar, rather than remembering which film actually received the award. To avoid such errors, always recall the specific headline that mentions Best Film or Royal Bengal Tiger award winner when answering questions on film festivals. Final Answer: The film that won the Best Film award at the 24th Kolkata International Film Festival in 2018 was The Third Wife.

Question 4

In the study of human memory, general knowledge, language, and concepts are considered parts of which type of memory system?

Accepted Answer

Introduction / Context: Psychology and cognitive science describe different types of memory systems in humans, each responsible for storing different kinds of information. Competitive exams often test whether you can distinguish between these memory types, such as semantic, episodic, and procedural memory. This question focuses on the type of memory that stores facts, meanings, concepts, and general knowledge about the world, which is vital for language use and understanding. Given Data / Assumptions: The information mentioned includes general knowledge, language, and concepts. The options are procedural memories, semantic memory, declarative memories, and episodic memory. We assume a standard introductory psychology classification of memory systems. The question is asking for the most specific and accurate label for the memory type described. Concept / Approach: Human long term memory is often divided into explicit (declarative) and implicit (non declarative) memory. Declarative memory is further divided into semantic memory and episodic memory. Semantic memory stores facts, meanings, vocabulary, symbols, and abstract concepts. Episodic memory stores personal experiences tied to specific times and places. Procedural memory, an implicit form of memory, stores skills and habits like riding a bicycle. Since the question highlights general knowledge, language, and concepts, it is clearly pointing toward semantic memory, which is the specialised form of declarative memory responsible for such information. Step-by-Step Solution: Step 1: Note the key descriptors in the question: general knowledge, language, and concepts. Step 2: Recall that procedural memory deals with how to perform actions and skills, not factual knowledge. Step 3: Remember that episodic memory stores autobiographical events such as personal experiences and episodes of life. Step 4: Know that semantic memory specifically handles meanings of words, factual information, and conceptual knowledge. Step 5: Recognise that declarative memory is the broader category that includes both semantic and episodic memory, while the question asks for the specific component that matches the description. Step 6: Therefore, identify semantic memory as the correct answer. Verification / Alternative check: To verify, think of examples: your knowledge that Delhi is the capital of India, that a triangle has three sides, or that a particular word has a certain meaning is stored in semantic memory. In contrast, remembering your last birthday party is episodic memory, and remembering how to drive a car is procedural memory. Since the question emphasises general knowledge and language, which clearly align with these semantic examples, semantic memory is the most appropriate choice. Declarative memories is too broad and does not specifically emphasise language and concepts alone. Why Other Options Are Wrong: procedural memories: These are skill based memories for actions and habits, such as playing a musical instrument, and do not primarily store general knowledge and language. declarative memories: This is an umbrella term that includes both semantic and episodic memory. It is not as specific as semantic memory for the information described in the question. episodic memory: This stores personal life events linked with time and place, such as first day at school, not abstract facts or vocabulary. Common Pitfalls: Candidates often confuse semantic memory with declarative memory because semantic memory is one type of declarative memory. Another pitfall is mixing up episodic and semantic memory, since both are explicit. Students may also choose procedural memory if they think broadly of learned information without recalling the specific definitions. To avoid these mistakes, remember that semantic memory is about facts and meanings, episodic memory is about experiences, and procedural memory is about skills. Final Answer: General knowledge, language, and concepts are primarily stored in semantic memory.

Question 5

The 13th G20 Summit held in 2018 took place in which country?

Accepted Answer

Introduction / Context: The Group of Twenty, or G20, is a major international forum for governments and central bank governors from the worlds largest economies. Each year, one member country hosts the G20 leaders summit. Exam questions in general knowledge often ask where a particular summit was held, especially when the summit discussed important global issues. The 13th G20 Summit took place in 2018, and remembering its host country is an important current affairs fact. Given Data / Assumptions: We are dealing with the 13th G20 Summit held in 2018. The options list India, Japan, Argentina, and None of the above. We assume the question is about the leaders summit, not a preparatory ministerial meeting. The exam expects you to know the host country for that summit. Concept / Approach: Each G20 summit is hosted by a rotating member country. For 2018, the summit was hosted in Buenos Aires, which is the capital city of Argentina. Many current affairs capsules before various competitive exams repeatedly mentioned that the 13th G20 Summit was held in Argentina, highlighting it as the first G20 summit in South America. By connecting the year 2018, the 13th summit sequence, and the city Buenos Aires, you can identify Argentina as the correct host country from the options. Step-by-Step Solution: Step 1: Note that the question specifies the 13th G20 Summit and the year 2018. Step 2: Recall that in 2018, news reports frequently mentioned the G20 leaders gathering in Buenos Aires. Step 3: Recognise Buenos Aires as the capital city of Argentina. Step 4: Among the options, identify Argentina as the country associated with Buenos Aires. Step 5: Choose Argentina as the correct answer, since neither India nor Japan hosted the 13th summit in that year. Verification / Alternative check: You can recall other years for comparison. India hosted the G20 summit in 2023, not 2018. Japan hosted the summit in 2019 at Osaka. Argentina is thus the only option that matches the year 2018 and the 13th summit number. If you remember that it was the first G20 summit ever held in South America, that detail also points directly toward Argentina, further verifying your answer. Why Other Options Are Wrong: India: A G20 member and later host, but it did not host the 13th summit in 2018. Japan: Hosted the G20 summit in 2019, not the 2018 edition. None of the above: Incorrect because Argentina, one of the listed options, is in fact the correct host country. Common Pitfalls: Some candidates may mix up years and host countries, for example confusing the Argentine summit with a later Indian or Japanese summit. Others may guess None of the above if they do not recognise Argentina immediately. To avoid such mistakes, it is useful to link each G20 year with a clear mental image: 2018 with Buenos Aires in Argentina, 2019 with Osaka in Japan, and later years with their respective hosts. Simple mental associations of year, city, and country can greatly improve recall in the exam hall. Final Answer: The 13th G20 Summit held in 2018 took place in Argentina.

Question 6

Which Indian state became the first to launch the pan India single emergency number 112 under the Emergency Response Support System?

Accepted Answer

Introduction / Context: Emergency numbers are vital for public safety, allowing citizens to quickly connect with police, fire, health, and other rescue services. India introduced a unified emergency number 112 under the Emergency Response Support System, similar to 911 in the United States. Current affairs questions often ask which state first implemented a new national initiative. This question focuses on the first Indian state to launch the pan India single emergency number 112. Given Data / Assumptions: The question refers to the unified emergency number 112 for India. The launch is under the Emergency Response Support System (ERSS). We must identify the first state to launch this system and number. The options are Haryana, Himachal Pradesh, Madhya Pradesh, and Uttar Pradesh. Concept / Approach: When a new nationwide system is rolled out, it is common for one pilot state to implement it first before broader adoption. For emergency number 112, Himachal Pradesh was selected as the first state where the ERSS system and the single number were officially launched. Many news articles highlighted Himachal Pradesh as the first state to provide the integrated service where existing emergency numbers like 100, 101, and 108 were merged into 112. Recognising this fact allows you to pick the correct option. Step-by-Step Solution: Step 1: Note that the question is about the first state to launch the pan India single emergency number 112. Step 2: Remember that 112 is part of the Emergency Response Support System, which integrates various emergency services. Step 3: Recall from current affairs that Himachal Pradesh was repeatedly mentioned as the first state to implement ERSS with number 112. Step 4: Compare the listed states and look for Himachal Pradesh among the options. Step 5: Select Himachal Pradesh as the correct answer. Verification / Alternative check: You can cross check by recalling that the official launch ceremony took place in Himachal Pradesh, where the Union Home Minister inaugurated the system. Reports emphasised that it was the first state to roll out 112 as a single emergency number, linking police, fire, health, and women helplines. Other large states such as Uttar Pradesh and Madhya Pradesh implemented it later, which confirms that Himachal Pradesh holds the first state distinction for this project. Why Other Options Are Wrong: Haryana: Although an important state in northern India, it was not the first to launch the pan India emergency number 112. Madhya Pradesh: Implemented emergency arrangements later, but did not have the first launch of 112 under ERSS. Uttar Pradesh: A large state where 112 is now active, yet it was not the pioneer state for this national system. Common Pitfalls: A common error is to guess a big or more frequently mentioned state like Uttar Pradesh or Madhya Pradesh, assuming that larger population automatically means being first in implementation. Another pitfall is to confuse 112 with other helpline numbers, such as 1091 or 181, and mix up related schemes. To avoid these issues, link the specific number 112 with the pilot implementation in the hilly state of Himachal Pradesh, which stands out if you have followed national news summaries for competitive exams. Final Answer: The first Indian state to launch the pan India single emergency number 112 under ERSS was Himachal Pradesh.

Question 7

Which of the following structures is recognised as the tallest building in the world?

Accepted Answer

Introduction / Context: Record breaking structures, especially the tallest buildings in the world, are popular topics in general knowledge and competitive exams. Such questions test your awareness of global landmarks and recent developments in architecture and engineering. The building recognised for many years as the tallest in the world is a symbol of modern design and is located in the Middle East. This question asks you to identify that building from a list of famous skyscrapers. Given Data / Assumptions: The question asks for the tallest building in the world. The options include Shanghai Tower, Burj Khalifa, Kingdom Clock Tower, and Wuhan Greenland Center. We assume the comparison is based on overall architectural height, which is the standard measure used by organisations that rank skyscrapers. Concept / Approach: The standard method of ranking the tallest buildings considers total architectural height from the ground to the highest fixed point of the structure, excluding temporary antennas. Burj Khalifa in Dubai has held the record as the tallest building in the world for many years, with a height of more than eight hundred meters. The other buildings listed are also very tall but do not exceed the height of Burj Khalifa. Recognising this name and associating it with the record for tallest building allows you to quickly select the correct answer. Step-by-Step Solution: Step 1: Recall the name of the building widely publicised as the tallest in the world. Step 2: Remember that Burj Khalifa, located in Dubai, has been described in media and textbooks as the tallest skyscraper globally. Step 3: Compare this with Shanghai Tower, Kingdom Clock Tower, and Wuhan Greenland Center, which are very tall but shorter than Burj Khalifa. Step 4: Look at the options and confirm that Burj Khalifa is listed. Step 5: Select Burj Khalifa as the correct option. Verification / Alternative check: You can verify by thinking about approximate heights. Burj Khalifa rises to more than eight hundred metres, while Shanghai Tower and the Kingdom Clock Tower are both shorter. Many current affairs compilations and school level general knowledge books specifically mention Burj Khalifa as the tallest building. Even if you do not remember exact heights, the name Burj Khalifa is repeatedly associated with this world record, which is strong confirmation that it is the correct answer when such a question appears. Why Other Options Are Wrong: Shanghai Tower: One of the tallest buildings in the world and the tallest in China, but it does not surpass the height of Burj Khalifa. Kingdom Clock Tower: A very tall structure in Saudi Arabia, but still not the tallest building globally. Wuhan Greenland Center: A major skyscraper project in China, yet it remains shorter than Burj Khalifa and does not hold the world record. Common Pitfalls: Candidates sometimes confuse the tallest building with other records such as tallest clock tower or tallest structure under construction. Others may select Shanghai Tower or Kingdom Clock Tower because they recall that these are extremely tall, without checking whether they exceed the height of Burj Khalifa. To avoid such mistakes, remember that Burj Khalifa is the standard answer for tallest building in the world and that other tall towers, even if they appear in news, have not overtaken this record in the period relevant for most exam questions based on this fact. Final Answer: The structure recognised as the tallest building in the world is Burj Khalifa.

Question 8

Which country became the first in the world to recognise orphanage trafficking as a form of modern slavery?

Accepted Answer

Introduction / Context: Modern slavery laws in many countries now address new and less visible forms of exploitation. One such issue is orphanage trafficking, where children are recruited or moved into institutions in order to attract donations or tourist volunteers. Around 2018, one country was widely reported as the first to recognise orphanage trafficking explicitly as a form of modern slavery in its legislation. This question checks whether you remember which country took that pioneering legal step. Given Data / Assumptions: The focus is on orphanage trafficking being recognised as slavery. We are asked to identify the first country to do this formally. The options are Mexico, Australia, Afghanistan, and India. We assume recognition is through official law or policy on modern slavery. Concept / Approach: To answer this, you need to recall international news about modern slavery laws. Australia passed a Modern Slavery Act and, in connection with this, became the first country to recognise orphanage trafficking as a form of modern slavery. This development was widely covered by global media and by organisations working on child protection and anti trafficking. Knowing this association between Australia and orphanage trafficking reforms allows you to select the correct option. Step-by-Step Solution: Step 1: Note that the question is about the first country to classify orphanage trafficking as slavery. Step 2: Recall that there was widespread discussion about a modern slavery law in Australia that specifically mentioned orphanage trafficking. Step 3: Recognise that this was described as a world first in many news reports. Step 4: Scan the options and identify Australia as the country that matches this information. Step 5: Choose Australia because the other countries listed did not receive similar recognition in this context during that period. Verification / Alternative check: You can verify by thinking of whether India, Mexico, or Afghanistan were highlighted in international news for such a legal innovation. While these countries face serious trafficking issues, the widely publicised recognition of orphanage trafficking as modern slavery came from Australias legislative changes. Articles quoting international organisations and child welfare groups repeatedly praised Australia for being the first to do this. Remembering that connection confirms that Australia is the right answer. Why Other Options Are Wrong: Mexico: Although trafficking is a problem in parts of Latin America, Mexico was not reported as the first country to legally recognise orphanage trafficking as slavery. Afghanistan: Known for conflict and human rights issues, but not for pioneering this specific modern slavery provision. India: Has various child protection and anti trafficking laws, but did not receive international recognition as the first state to classify orphanage trafficking in this specific way. Common Pitfalls: Students may guess India because the country has many orphanages and strong public concern about child trafficking. Others might choose a country with high trafficking risks, assuming that the problem country must also be the legislative pioneer. However, legal innovation can come from a country with strong international advocacy networks and a tradition of human rights legislation. In this case, that country was Australia. To avoid confusion, link orphanage trafficking recognition clearly with Australias Modern Slavery Act when revising current affairs. Final Answer: The first country to recognise orphanage trafficking as a form of modern slavery was Australia.

Question 9

After the resignation of Urjit Patel in December 2018, who was appointed as the new Governor of the Reserve Bank of India?

Accepted Answer

Introduction / Context: The Governor of the Reserve Bank of India is a key figure in the Indian economy, responsible for monetary policy, regulation of banks, and financial stability. Changes in this position are significant events and often feature in current affairs questions. In December 2018, after the resignation of Governor Urjit Patel, the Government of India appointed a new RBI Governor. This question asks you to recall the name of that successor. Given Data / Assumptions: Urjit Patel resigned from the post of RBI Governor in December 2018. A new Governor was appointed immediately after his resignation. The options list Urjit Patel, Shaktikanta Das, Raghuram Rajan, and Smt. Pallavi Nair. We assume the question refers to the official appointment notified by the Government of India. Concept / Approach: To answer this, you must connect the timeline of RBI Governors. Raghuram Rajan served before Urjit Patel, and Shaktikanta Das was appointed after Urjit Patel. In December 2018, news outlets widely reported that former Economic Affairs Secretary Shaktikanta Das had been chosen as the new RBI Governor. Recognising that the appointment came immediately after Urjit Patels resignation allows you to identify Shaktikanta Das as the correct option. Step-by-Step Solution: Step 1: Recall the sequence of RBI Governors: Raghuram Rajan, followed by Urjit Patel, followed by Shaktikanta Das. Step 2: Note that the question specifically refers to the new Governor appointed after Urjit Patels resignation in December 2018. Step 3: Remember that in December 2018, Shaktikanta Das was appointed to this post. Step 4: Compare this recollection with the options given. Step 5: Select Shaktikanta Das as the correct answer. Verification / Alternative check: You can verify by recalling that media discussions at that time emphasised Shaktikanta Dass experience in the Finance Ministry and his role in major economic decisions. There was also heavy coverage of market reactions to his appointment. Since Raghuram Rajan had already left the position earlier and Urjit Patel was the one resigning, neither of them can be the incoming Governor described in the question. The presence of a relatively unknown name such as Smt. Pallavi Nair further confirms that this is a distractor, and Shaktikanta Das is the only realistic and correct option. Why Other Options Are Wrong: Urjit Patel: He is the Governor who resigned in December 2018, not the person appointed after that resignation. Raghuram Rajan: He served as RBI Governor before Urjit Patel and left the post earlier, so he was not appointed in December 2018. Smt. Pallavi Nair: This name does not correspond to any official RBI Governor in the relevant timeline and is included only as a distractor. Common Pitfalls: Some candidates may confuse the order of RBI Governors, especially between Raghuram Rajan and Urjit Patel. Others might misread the question and think it asks who resigned, rather than who was appointed after the resignation. To avoid these errors, remember the correct sequence and pay attention to words like after, new, or successor. Keeping a simple list of RBI Governors with their key dates during your exam preparation helps make such questions straightforward. Final Answer: The new Governor of the Reserve Bank of India appointed after Urjit Patels resignation in December 2018 was Shaktikanta Das.

Question 10

Which NASA spacecraft was sent on a mission to study the planet Jupiter?

Accepted Answer

Introduction / Context: Space missions to planets in our solar system are important achievements in science and technology. The United States space agency NASA has launched several missions to study Jupiter, the largest planet in the solar system. This question asks you to identify the name of the NASA spacecraft specifically sent to study Jupiter in detail, including its atmosphere, magnetic field, and internal structure. Given Data / Assumptions: The mission is a NASA spacecraft dedicated to the study of Jupiter. The options are JUNO, LUNO, MONO, and TANO, which sound similar but only one is correct. We assume that the question refers to the well known solar powered spacecraft that entered Jupiters orbit in the 2010s. Concept / Approach: NASA named the Jupiter mission Juno. The spacecraft Juno was launched to investigate Jupiters composition, gravity field, magnetic field, and polar magnetosphere. The other names listed are not real NASA missions and are designed to act as distractors by sounding like Juno. Recognising the distinctive and correct name Juno among the options, and knowing that it is associated with Jupiter, allows you to answer correctly. Step-by-Step Solution: Step 1: Read the question carefully and note that it asks for a NASA mission to Jupiter. Step 2: Recall that the NASA spacecraft Juno was specifically sent to orbit and study Jupiter. Step 3: Check the options and look for the name that exactly matches this mission. Step 4: Identify JUNO among the options as the correct spelling and name of this spacecraft. Step 5: Choose JUNO as the answer, ignoring the similar sounding but incorrect names. Verification / Alternative check: To verify, you can recall basic facts about the Juno mission. The spacecraft uses solar panels instead of nuclear power, travels in a polar orbit around Jupiter, and has instruments to measure radiation, magnetic fields, and atmospheric composition. Public sources consistently refer to this mission as Juno. There are no NASA missions to Jupiter called Luno, Mono, or Tano, so the presence of those names in the options further confirms that they are distractors, leaving Juno as the only accurate choice. Why Other Options Are Wrong: LUNO: Not the name of a NASA Jupiter mission, and no major spacecraft by this name is associated with Jupiter. MONO: Another invented name that sounds like Juno but does not correspond to an actual Jupiter mission. TANO: Also not the official name of any well known NASA spacecraft sent to study Jupiter. Common Pitfalls: Since the distractor options are designed to sound similar, students may misread the spelling or get confused in a hurry. Another pitfall is to confuse Juno with earlier missions like Galileo, which also studied Jupiter but is not listed among the options. To avoid these mistakes, slow down enough to read the spellings clearly and mentally connect the name Juno with Jupiter and with its specific research goals before selecting your answer. Final Answer: The NASA spacecraft sent on a mission to study Jupiter is JUNO.

Question 11

Which of the following healthcare professionals is generally not authorised to make a medical diagnosis of a patient?

Accepted Answer

Introduction / Context: In healthcare systems, different professionals have clearly defined roles, responsibilities, and legal scopes of practice. Some professionals, such as medical doctors and specialists, are authorised to diagnose and treat diseases, while others support patient care in different ways. This question tests whether you know which role, among those listed, generally does not have independent authority to make a formal medical diagnosis of a patient. Given Data / Assumptions: The focus is on the ability to diagnose patients. The options are nurse, specialist, physicians assistant, and medical doctor. We assume a standard healthcare system where specialists and medical doctors are licensed to diagnose, and physicians assistants work under a physicians supervision. Concept / Approach: Medical diagnosis is usually carried out by licensed physicians and specialists who have completed medical school and additional training. A specialist is a physician with extra expertise in a particular field, such as cardiology or neurology, and clearly has diagnostic authority. A medical doctor is the general term for such licensed physicians. A physicians assistant can often perform many tasks and may participate in diagnosis under the supervision of a doctor, depending on regulations. Nurses play an essential role in patient care, monitoring, and support, but generally do not have independent authority to make formal medical diagnoses, even though they may perform assessments and report findings to doctors. Step-by-Step Solution: Step 1: Identify which options describe licensed medical doctors: specialist and medical doctor clearly fall into this category. Step 2: Recognise that physicians assistants are trained to assist doctors and may be involved in treatment and preliminary assessment, often under physician supervision. Step 3: Understand that nurses focus primarily on nursing care, observations, and implementing treatment plans, not on making independent medical diagnoses. Step 4: Compare all four roles and see which one is the least associated with diagnostic authority. Step 5: Conclude that nurse is the correct option as the professional who is generally not authorised to diagnose. Verification / Alternative check: To verify, think about typical hospital procedures. When a patient arrives with symptoms, nurses take vital signs and perform initial assessments, but the final diagnosis is documented by physicians or specialists. Physicians assistants may examine patients and help in diagnosis but usually under supervision. Nurses often implement physician orders and monitor patient progress rather than formally defining the diagnosis. This consistent pattern across health systems supports the choice of nurse as the correct answer for this question. Why Other Options Are Wrong: Specialist: A specialist is a physician with advanced training in a specific field and is fully authorised to diagnose and manage complex conditions. Physician's assistant: This role often includes conducting examinations and contributing to diagnosis under a doctors supervision, so it is closer to diagnostic work than nursing. Medical doctor: The main professional responsible for making diagnoses, prescribing treatment, and leading patient management. Common Pitfalls: Some candidates may mistakenly think that nurses diagnose because they observe patients closely and sometimes identify problems early. However, there is an important difference between recognising symptoms and formally assigning a medical diagnosis. Others may misunderstand the physicians assistant role, thinking they are more limited than they usually are. To avoid confusion, remember that nurses provide nursing assessments and care, while doctors and specialists hold the primary legal authority to diagnose. Final Answer: Among the professionals listed, the one generally not authorised to make a medical diagnosis is the nurse.

Question 12

Which of the following statements about personal flotation devices (PFDs) is true?

Accepted Answer

Introduction / Context: Personal flotation devices, often called life jackets, are crucial safety equipment when boating, swimming in open water, or participating in water sports. Safety education materials emphasise correct usage, maintenance, and fitting of PFDs. Exams sometimes include questions from basic safety guidelines, and this question asks you to identify the accurate statement among several that describe PFD use and care. Given Data / Assumptions: The subject is personal flotation devices (PFDs). We must choose one true statement from four given options. The options mention ease of putting on PFDs in water, cleaning methods, performance in shallow water, and fit for children. Concept / Approach: Water safety rules stress that PFDs should be worn before entering the water because putting them on while already in the water can be hard or even impossible in rough conditions. They also warn against using harsh chemicals like gasoline for cleaning PFDs, as this can damage materials. A PFD will float regardless of water depth, shallow or deep, because flotation depends on buoyancy, not depth. For children, a PFD must fit snugly and securely, not loosely, to prevent slipping off. Based on these principles, the only correct statement is that PFDs are difficult to put on in the water. Step-by-Step Solution: Step 1: Consider option A, which states that PFDs are difficult to put on in the water. This matches safety advice that PFDs must be worn before going into the water. Step 2: Examine option B, which suggests cleaning a PFD with gasoline. Safety guidelines clearly warn against using gasoline or strong solvents on PFDs. Step 3: Look at option C, which claims that PFDs do not float well in shallow water. Flotation is independent of depth, so this statement is incorrect. Step 4: Evaluate option D, which says children's PFDs should fit loosely. In reality, children need snug fitting PFDs to prevent them from slipping out. Step 5: Conclude that option A is the only true statement and is therefore the correct answer. Verification / Alternative check: You can verify by thinking about practical scenarios. If someone falls overboard without wearing a PFD, they must struggle in the water, possibly in waves or strong current, to put a PFD on, which is very difficult and dangerous. Boating safety courses always instruct passengers to put on PFDs before leaving shore. Cleaning instructions from manufacturers also prohibit gasoline and recommend mild soap and water. These widely accepted guidelines confirm that option A reflects accurate safety information about PFDs. Why Other Options Are Wrong: Use gasoline to clean a PFD coated with oil or grease: Gasoline can weaken or damage the PFD fabric and flotation material, making it unsafe to use. PFDs do not float well in shallow water: The buoyancy of a PFD works the same in shallow and deep water as long as the device is correctly designed and worn. Children's PFDs should fit loosely: Loose PFDs are dangerous, especially for children, because they may slip off when the child is in the water. Common Pitfalls: Students may wrongly assume that gasoline is a strong cleaner suitable for all types of equipment or that shallow water somehow changes flotation behavior. Others might think a loose fit is more comfortable for children without realising that safety comes first. To avoid these errors, remember that all safety equipment must be used as directed by manufacturers and safety authorities. PFDs should be worn early, cleaned gently, and fitted snugly, especially for children. Final Answer: The true statement is that PFDs are difficult to put on in the water.

Question 13

The Government of India decided to introduce a new 100 rupee commemorative coin featuring the image of which former Prime Minister of India?

Accepted Answer

Introduction / Context: Commemorative coins are issued by governments to honour important national leaders and mark significant anniversaries. In India, special denomination coins have been released to pay tribute to prominent figures such as former Prime Ministers. Around 2018, the Government of India decided to introduce a new 100 rupee coin in memory of a former Prime Minister who had recently passed away. This question tests your knowledge of which leader was honoured through this commemorative coin. Given Data / Assumptions: The denomination of the coin is 100 rupees. It is a commemorative coin issued by the Government of India. The coin features the image of a former Prime Minister. The options are Jawaharlal Nehru, Indira Gandhi, Atal Bihari Vajpayee, and Rajiv Gandhi. Concept / Approach: To answer, you need to recall recent political and economic news. In 2018, a 100 rupee commemorative coin was approved to honour former Prime Minister Atal Bihari Vajpayee, who passed away in the same year. The coin featured his portrait and related inscriptions. Other former Prime Ministers like Jawaharlal Nehru, Indira Gandhi, and Rajiv Gandhi have been honoured in many ways, but the specific new 100 rupee coin launched during that period was associated with Atal Bihari Vajpayee. Recognising that link helps you identify the correct option. Step-by-Step Solution: Step 1: Recall the news about a special 100 rupee coin announced near the time of Atal Bihari Vajpayees birth anniversary after his passing. Step 2: Remember that this coin was explicitly described as a commemorative coin featuring Vajpayees portrait. Step 3: Check the options and find the name that matches this memory. Step 4: Identify Atal Bihari Vajpayee among the four former Prime Ministers listed. Step 5: Select Atal Bihari Vajpayee as the correct answer. Verification / Alternative check: You can verify by matching the timing. Atal Bihari Vajpayee passed away in 2018, and soon after, the Government of India announced a commemorative coin for him. Jawaharlal Nehru, Indira Gandhi, and Rajiv Gandhi had been commemorated earlier in various forms, but there was no major new 100 rupee coin announcement for them around 2018. This timing and the widely reported coin release confirm that the new 100 rupee coin in the question refers to Atal Bihari Vajpayee. Why Other Options Are Wrong: Jawaharlal Nehru: The first Prime Minister of India, honoured in many ways, but not the specific new 100 rupee coin described in this question. Indira Gandhi: Also commemorated separately, but no widely publicised 100 rupee coin launch in 2018 for her. Rajiv Gandhi: Another former Prime Minister remembered through other means, yet not the subject of the 100 rupee coin announced at that time. Common Pitfalls: Candidates may confuse various commemorative stamps, coins, and schemes dedicated to different leaders and assume that any well known Prime Minister might be the answer. Others may guess based on personal familiarity with the name instead of recalling the specific news about the 100 rupee coin. To avoid such confusion, link each major commemorative announcement with a clear mental image: for this coin, imagine the portrait and name of Atal Bihari Vajpayee on a new, special denomination coin. Final Answer: The new 100 rupee commemorative coin described in the question features former Prime Minister Atal Bihari Vajpayee.

Question 14

Who is serving as the Chairman of the Indian Space Research Organisation (ISRO) from 2018 onward, succeeding A. S. Kiran Kumar?

Accepted Answer

Introduction / Context: The Indian Space Research Organisation, commonly known as ISRO, is Indias national space agency and is widely admired for successful missions such as Chandrayaan and Mangalyaan. The Chairman of ISRO is a high profile scientific leader whose appointment frequently appears in current affairs sections of exams. In 2018, a new Chairman took over from A. S. Kiran Kumar. This question asks you to identify that successor. Given Data / Assumptions: The position is Chairman of ISRO. The time frame is from 2018 onward, after A. S. Kiran Kumar. The options are Kailasavadivoo Sivan, G. Satheesh Reddy, A. S. Kiran Kumar, and K. Radhakrishnan. Concept / Approach: To answer this question, you need to connect the leadership timeline at ISRO. K. Radhakrishnan served earlier, followed by A. S. Kiran Kumar. In January 2018, Kailasavadivoo Sivan, often referred to as K. Sivan, was appointed as the new Chairman of ISRO. G. Satheesh Reddy is associated with defence research and missile programmes, not with the post of ISRO Chairman. Recognising this sequence allows you to correctly select Kailasavadivoo Sivan as the answer. Step-by-Step Solution: Step 1: Recall that K. Radhakrishnan was succeeded by A. S. Kiran Kumar as Chairman of ISRO. Step 2: Note that the question asks about the Chairman who took over after A. S. Kiran Kumar in 2018. Step 3: Remember that Kailasavadivoo Sivan, commonly known as K. Sivan, was appointed to this role in early 2018. Step 4: Review the options and identify Kailasavadivoo Sivan as the name that matches this information. Step 5: Select Kailasavadivoo Sivan as the correct answer. Verification / Alternative check: You can verify by thinking of major ISRO missions and news events around 2018, including announcements where K. Sivan addressed the media as Chairman. Press conferences for launch vehicles, Chandrayaan missions, and other space projects often quoted him. A. S. Kiran Kumar is mentioned as the outgoing Chairman, while K. Radhakrishnan and earlier leaders belong to previous periods. G. Satheesh Reddy appears more in defence and missile programme contexts. These associations confirm Kailasavadivoo Sivan as the right choice. Why Other Options Are Wrong: G. Satheesh Reddy: A prominent figure in defence research and missile development, but not appointed as Chairman of ISRO in 2018. A. S. Kiran Kumar: The predecessor who completed his term as Chairman of ISRO before the new appointment in 2018. K. Radhakrishnan: An earlier ISRO Chairman whose tenure ended before A. S. Kiran Kumar took over. Common Pitfalls: Exam candidates sometimes confuse leaders of different scientific organisations, such as ISRO, DRDO, and the space commission. Another common error is remembering the order of Chairmen incorrectly, mixing up K. Radhakrishnan, A. S. Kiran Kumar, and K. Sivan. To avoid this, keep a simple chronological list and connect each name with a major mission or news event, such as Chandrayaan missions for both K. Radhakrishnan and K. Sivan, but noting the different time periods in which they served. Final Answer: The Chairman of ISRO who took over in 2018 after A. S. Kiran Kumar is Kailasavadivoo Sivan.

Question 15

In December 2018, President's Rule was imposed in which Indian state or union territory?

Accepted Answer

Introduction / Context: In the Indian constitutional system, Presidents Rule refers to a situation where the state government is dismissed and the central government takes direct control of the state administration. This usually happens when no party can form a stable government or governance cannot be carried on in accordance with the Constitution. In late 2018, one state saw the imposition of Presidents Rule after a period of Governors Rule. This question asks you to identify that state or union territory. Given Data / Assumptions: The time frame is December 2018. The subject is the imposition of Presidents Rule. The options are Haryana, Delhi, Telangana, and Jammu and Kashmir. Concept / Approach: To answer, you must recall recent political events in Indian states. Jammu and Kashmir had been under Governors Rule after the collapse of a coalition government. When the six month period of Governors Rule ended in December 2018 and no stable government could be formed, the state was placed under Presidents Rule. Other states listed in the options did not have Presidents Rule imposed in that specific period. By linking the timeline and the constitutional events in Jammu and Kashmir, you can identify the correct option. Step-by-Step Solution: Step 1: Recall that a coalition government in Jammu and Kashmir collapsed in 2018, leading to Governors Rule. Step 2: Remember that after six months of Governors Rule, if no government is formed, Presidents Rule can follow. Step 3: Note that this transition happened in December 2018 for Jammu and Kashmir. Step 4: Check the options and find Jammu and Kashmir listed among them. Step 5: Select Jammu and Kashmir as the correct answer. Verification / Alternative check: You can quickly verify by thinking of whether Haryana, Delhi, or Telangana faced similar constitutional events in December 2018. None of these experienced Presidents Rule at that time. Jammu and Kashmir was repeatedly mentioned in national news about the shift from Governors Rule to Presidents Rule just before the end of the year. This strong media coverage confirms that Jammu and Kashmir is the only correct choice from the options given. Why Other Options Are Wrong: Haryana: Normal elected government was in place and no Presidents Rule was imposed in December 2018. Delhi: A union territory with a special status and an elected government, but no Presidents Rule was introduced then. Telangana: Underwent elections and the return of a stable government in 2018, not Presidents Rule. Common Pitfalls: Students sometimes confuse different forms of central control, such as Governors Rule, Presidents Rule, and situations of suspended assemblies. Others may vaguely remember unrest or elections in several states and mix up which state had Presidents Rule and when. To avoid these problems, connect each constitutional development with a clear time frame and state. For Jammu and Kashmir, remember the sequence of coalition government collapse, Governors Rule, and then Presidents Rule in December 2018. Final Answer: Presidents Rule was imposed in Jammu and Kashmir in December 2018.

Question 16

Kalamkari, a traditional Indian style of hand painted or block printed textile art, is primarily associated with which state?

Accepted Answer

Introduction / Context: India has a rich heritage of traditional art forms, many of which are closely tied to specific regions or states. Kalamkari is a well known style of textile art that uses either freehand painting with a pen or hand block printing on cotton fabrics. General knowledge questions frequently ask you to match such art forms with the states they are most associated with. This question focuses on identifying the state that is especially famous for Kalamkari work. Given Data / Assumptions: The art form is Kalamkari painting or textile art. Kalamkari involves hand painting or block printing on fabric, traditionally with natural dyes. The options are Tamil Nadu, Kerala, Karnataka, and Andhra Pradesh. Concept / Approach: Kalamkari is historically linked with regions in present day Andhra Pradesh and parts of Telangana. Famous centres include the towns of Srikalahasti and Machilipatnam, which are located in Andhra Pradesh. Many exam guides highlight Kalamkari as a traditional art of Andhra Pradesh, even though the style later spread to other regions. Remembering these associations helps you choose the correct state from the options given. Step-by-Step Solution: Step 1: Recall that Kalamkari is a traditional textile art involving hand drawn or block printed designs using natural dyes. Step 2: Think of the main centres for Kalamkari, such as Srikalahasti and Machilipatnam. Step 3: Recognise that these towns are located in Andhra Pradesh. Step 4: Check the options and locate Andhra Pradesh among the listed states. Step 5: Select Andhra Pradesh as the correct answer. Verification / Alternative check: To verify, you can recall that many handicraft exhibitions and government documentation refer to Andhra Pradesh Kalamkari, often describing the detailed temple themes and mythological scenes painted on cloth. Tamil Nadu, Kerala, and Karnataka each have their own distinct art traditions, such as Tanjore paintings from Tamil Nadu and Theyyam from Kerala, but Kalamkari is most strongly and repeatedly linked with Andhra Pradesh in exam oriented study material. Why Other Options Are Wrong: Tamil Nadu: Known for classical dance forms and different visual arts, but Kalamkari is not primarily identified with this state. Kerala: Famous for murals and performing arts like Kathakali, rather than Kalamkari textile painting. Karnataka: Has rich craft traditions, but Kalamkari is not the main textile art associated with it in exam level general knowledge. Common Pitfalls: Students may confuse Kalamkari with South Indian paintings generally and guess Tamil Nadu or Karnataka without recalling specific geographical centres. Others may simply pick a southern state at random. To avoid such mistakes, associate the word Kalamkari directly with Andhra Pradesh and with places like Srikalahasti, which frequently appear alongside this art form in textbooks and competitive exam notes. Final Answer: Kalamkari painting is primarily associated with the state of Andhra Pradesh.

Question 17

A DC series motor should never be operated under which of the following load conditions?

Accepted Answer

Introduction / Context: In electrical engineering and basic technical general knowledge, DC motors are important machines whose operating conditions must be properly controlled to avoid damage. A DC series motor is a particular type of motor where the field winding is connected in series with the armature. Its speed characteristics make it unsuitable for certain conditions. This question asks you to identify the load condition under which a DC series motor should never be operated, because doing so can cause dangerously high speed and possible mechanical failure. Given Data / Assumptions: The motor type is a DC series motor. The options describe different load conditions: full load, half load, no load, and at any load. We assume basic theoretical understanding of speed and torque characteristics of DC series motors. Concept / Approach: In a DC series motor, field current and armature current are the same because the field winding is connected in series with the armature. At no load, the current drawn is small, leading to a weak field. Since motor speed is inversely related to the flux, a very weak field causes the speed to rise dangerously. Under no load, the speed can become excessively high, risking mechanical damage or failure. Therefore, such motors are never run without sufficient load connected. They are instead designed to start and operate under load, as in traction and hoisting applications. Step-by-Step Solution: Step 1: Recall that in a DC series motor, field flux increases with load current. Step 2: Understand that at no load, current is low, so field flux is weak. Step 3: Remember that motor speed is approximately inversely proportional to flux, so a weak flux leads to a very high speed. Step 4: Conclude that running the motor at no load can make the rotor speed rise to unsafe levels. Step 5: Compare this with full load and half load conditions, where sufficient current and flux keep speed under control, and select no load as the condition to avoid. Verification / Alternative check: You can verify this concept by considering that DC series motors are commonly used in applications where they start under load, such as electric traction or cranes. Textbooks clearly warn that these motors should not be started or operated without load because of the risk of overspeed. Under full load or half load, although speed varies, it stays within a manageable range due to higher flux. This theoretical understanding and practical usage pattern confirm that no load operation is the forbidden condition. Why Other Options Are Wrong: Full load: At full load, current and flux are high, and speed is lower and more stable, so the motor is safe in properly rated conditions. Half load: While speed will be higher than at full load, it still remains within acceptable limits for a correctly designed motor. At any load: This statement is too broad and incorrect, because DC series motors are in fact intended to work under load, not without load. Common Pitfalls: Students sometimes confuse the behaviour of series and shunt motors, or they think that maximum load is always the most dangerous condition. In reality, for a series motor, very low load or no load is more dangerous due to overspeed. Another pitfall is assuming that no load operation is safe because many machines are tested at no load. To avoid these mistakes, specifically remember: DC series motor plus no load equals unsafe high speed, so such operation is strongly discouraged. Final Answer: A DC series motor should never be operated on no load.

Question 18

Which of the following is an example of an expressed power held by the United States Congress?

Accepted Answer

Introduction / Context: In civics and political science, the term expressed powers refers to powers that are specifically listed in a constitution or foundational legal document. In the United States, the Constitution explicitly grants certain powers to Congress, such as the power to declare war and raise and support armies. This question tests whether you can identify these expressed powers from the list of options provided. Given Data / Assumptions: The powers under consideration are declaring war and maintaining an army. We are asked to choose which options represent expressed powers of Congress. The answers include each power separately, a combined option, and None of the above. Concept / Approach: The United States Constitution, particularly Article I, Section 8, lists several specific powers of Congress. Among them are the power to declare war and the power to raise and support armies and navies. These are classic examples of expressed powers. The question lists these two powers separately in options A and B and then together in option C, so you must recognise that both are expressed powers and select the combined answer Both A and B. Step-by-Step Solution: Step 1: Recall that an expressed power is one that is clearly listed in the Constitution. Step 2: Recognise that the power to declare war is explicitly granted to Congress. Step 3: Remember that the power to raise and maintain an army is also explicitly granted to Congress. Step 4: Look at the answer options and note that A corresponds to declaring war and B corresponds to maintaining an army. Step 5: Since both A and B describe expressed powers, select option C, which states Both A and B. Verification / Alternative check: To verify, think of other sources you may have studied. Textbooks on American government usually present a list of congressional powers, where declaring war and raising armed forces appear prominently. These are not implied or reserved powers; they are direct, explicit powers. Because the question is asking for an example of expressed power and both A and B satisfy this condition, the combined option C must be correct. None of the above cannot be right because it would contradict the clear constitutional text. Why Other Options Are Wrong: declaring war: While this is an expressed power, option A alone ignores that maintaining an army is also an expressed power, so the more complete combined option is better. maintaining an army: Similarly, this alone is correct but incomplete when the test offers a combined option that includes both correct powers. None of the above: Incorrect, because both declaring war and maintaining an army are indeed expressed powers of Congress. Common Pitfalls: A common mistake is to select only one of the individual correct options, thinking that the exam wants a single example instead of recognising that a combined answer represents a more accurate choice. Another error is to misunderstand the term expressed powers and confuse them with implied powers that arise from broader constitutional clauses. To avoid this, remember that expressed powers are specifically written in the constitutional text, and both declaring war and maintaining an army clearly fall into that category. Final Answer: An example of expressed powers held by Congress is Both A and B, which covers both declaring war and maintaining an army.

Question 19

The family as a social institution is found in which of the following?

Accepted Answer

Introduction / Context: Sociology studies social institutions, which are organised patterns of beliefs and behaviour that meet basic social needs. The family, as an institution, plays a central role in socialisation, care, and emotional support. Some institutions vary greatly from one culture to another, but the family is often described as a cultural universal. This question checks whether you understand how widely the family as a social institution is found across human societies. Given Data / Assumptions: The subject is the family as a social institution. The options range from every society to only half of societies or mostly high income societies. We assume the sociological definition of family, which can include different structures such as nuclear, joint, extended, and other forms. Concept / Approach: In sociology, some features of social life are considered cultural universals, meaning they appear in all known human societies, although their specific forms may differ. The family is widely recognised as one of these universals. While family structure and marriage customs vary, every society has a system of family relationships that organises reproduction, child rearing, and kinship. Therefore, the correct answer is that the family is found in every society, not just in high income societies or most societies. Step-by-Step Solution: Step 1: Recall that the family is described in sociology as a fundamental social institution. Step 2: Think about the idea of cultural universals, which include institutions like family, religion, and language. Step 3: Note that even though forms of family life differ, some kind of family arrangement exists everywhere. Step 4: Compare this understanding with the options, paying attention to the word every in option A. Step 5: Select every society as the correct option, since the family exists in all known human communities. Verification / Alternative check: You can verify by considering different types of societies, from hunter gatherer tribes to modern urban nations. In each case, there is some recognised unit that handles reproduction, child care, and kinship ties, even if it is not called a nuclear family. Anthropological studies consistently report variations in family form but not the absence of family as a concept. This strongly supports the statement that the family is present in every society rather than just in some or only in high income countries. Why Other Options Are Wrong: high income nations but not in most low income nations: This is incorrect because families clearly exist in low income societies as well, often with strong kinship networks. most but not all societies: This implies that some societies lack families altogether, which contradicts anthropological evidence. about half of human societies: Far too low a figure and ignores the universal presence of family structures. Common Pitfalls: Some students interpret family too narrowly, thinking only of the modern nuclear family and then reasoning that not all societies have that exact structure. This can lead them to choose most societies instead of every society. Others may be misled by economic categories, imagining that social institutions like family must differ sharply between rich and poor nations. To avoid such errors, focus on the functional role of the family rather than its specific form. Once you do that, it becomes clear that every society has some family institution. Final Answer: The family as a social institution is found in every society.

Question 20

Which year was declared National Mathematics Year in India as a tribute to mathematician Srinivasa Ramanujan?

Accepted Answer

Introduction / Context: India has honoured many great scientists and mathematicians through national celebrations and special commemorative years. Srinivasa Ramanujan, a world famous Indian mathematician, made deep contributions to number theory and other areas of mathematics. To celebrate his legacy and inspire interest in mathematics, one particular year was declared National Mathematics Year in India. This question asks you to identify that year. Given Data / Assumptions: The question is about National Mathematics Year in India. The year was chosen as a tribute to Srinivasa Ramanujan. The options are 2012, 2013, 2011, and 2010. Concept / Approach: Ramanujan was born in 1887. The year 2012 marked the one hundred and twenty fifth anniversary of his birth. To commemorate this milestone and to promote the study of mathematics, the Government of India declared 2012 as National Mathematics Year. Many seminars, competitions, and educational programmes were organised during this year. Recognising this connection between the anniversary year and the declaration helps you choose 2012 from the options. Step-by-Step Solution: Step 1: Remember that Srinivasa Ramanujan was born in 1887. Step 2: Calculate the 125th birth anniversary: 1887 plus 125 equals 2012. Step 3: Recall that the Government of India declared that anniversary year as National Mathematics Year. Step 4: Check the options and identify 2012 as one of the choices. Step 5: Select 2012 as the correct answer. Verification / Alternative check: You can verify by recalling that 2012 saw several national events dedicated to mathematics, including special lectures, workshops, and competitions. Educational institutions were encouraged to highlight Ramanujans life and work, and many exam preparation materials mention that 2012 was marked as National Mathematics Year in his honour. The surrounding years 2010, 2011, and 2013 do not align with the 125th anniversary, which further confirms that 2012 is correct. Why Other Options Are Wrong: 2013: Does not correspond to a major Ramanujan anniversary and was not declared National Mathematics Year. 2011: One year before the 125th birth anniversary and not designated for this specific tribute. 2010: Also not linked to any major Ramanujan related anniversary or National Mathematics Year declaration. Common Pitfalls: Some candidates may confuse the exact anniversary year or miscalculate the gap between 1887 and the commemorative year. Others may simply guess a date close to 2012 without doing the basic arithmetic. To avoid such mistakes, remember both the birth year 1887 and the special role of the 125th anniversary. Adding 125 gives 2012 directly and makes it easy to link that year with National Mathematics Year in exam questions. Final Answer: National Mathematics Year in India, declared as a tribute to Srinivasa Ramanujan, was the year 2012.
