Question 1

Assertion (A): Mr. Modi became the prime minister of the country. Reason (R): Mr. Modi was the leader of a national party.

Accepted Answer

The prime minister needs to be elected by the members of the Parliament.

Question 2

Assertion–Reason (Food Security Policy): Assertion (A): The government provides food grains to the poor at a very low price. Reason (R): The poor cast their vote in large numbers in the elections.

Accepted Answer

Introduction / Context:This Assertion–Reason item tests whether a true observation about public policy (food grains to the poor at subsidized prices) is being explained accurately by a political claim (that the poor vote in large numbers). The core skill is to distinguish factual truth from causal sufficiency and policy rationale.Given Data / Assumptions:A: The State supplies subsidized food grains to poor households.R: The poor participate in elections in large numbers.General aims of food security policies include reducing hunger, improving nutrition, stabilizing prices, and ensuring minimum consumption levels.Concept / Approach:Evaluate A and R independently for truth, then check whether R is the correct explanation of A. A true assertion does not necessarily imply that any true statement about the same domain is its cause; explanation requires policy objectives and institutional design to align with the stated reason.Step-by-Step Solution:1) Truth of A: Many governments operate food-security programs targeting poor households with subsidized staples; so A is true in substance.2) Truth of R: In many democracies, poorer citizens do participate robustly in voting; thus R can be true as an empirical tendency.3) Causal link test: The principal rationale for food subsidies is social protection and food security, not merely electoral turnout. Even if political factors influence policy, the stated policy logic (hunger alleviation, nutrition) is the proximate explanation. Hence R does not correctly explain A.Verification / Alternative check:Consider policy documents and program goals (food security, price stabilization, public health). These reasons suffice to justify A without invoking voter-turnout patterns.Why Other Options Are Wrong:(a) wrongly treats electoral participation as the direct policy cause; (c) mislabels R as false; (d) contradicts A’s truth; “None” is unnecessary.Common Pitfalls:Confusing political economy influences with official policy objectives; assuming correlation equals causation.Final Answer:Both A and R are true, but R is not the correct explanation of A.

Question 3

Assertion–Reason (Devaluation and Exports): Assertion (A): The country’s exports became very attractive in terms of price to importers. Reason (R): The currency of the country was devalued.

Accepted Answer

Introduction / Context:This problem examines basic international economics: how nominal exchange rate changes affect the foreign-currency prices of a country’s exports and, therefore, export competitiveness.Given Data / Assumptions:A: Export prices became attractive to foreign buyers.R: The domestic currency was devalued (i.e., it buys fewer units of foreign currency).Standard assumption: pass-through from exchange rate to export prices is significant in the short run, ceteris paribus.Concept / Approach:Devaluation typically reduces the foreign-currency price of domestically produced goods (holding domestic costs and margins constant), improving price competitiveness of exports. We check truth of A and R and then causal adequacy of R in explaining A.Step-by-Step Solution:1) R is true by premise: devaluation occurred.2) If exporters adjust minimally, the foreign-currency price falls, making products “attractive” to importers abroad; hence A is true.3) The explanation is direct: devaluation lowers relative price, boosting price-based competitiveness; thus R correctly explains A.Verification / Alternative check:Export surges are often associated with sustained devaluation episodes, controlling for demand, costs, and non-price factors (quality, logistics).Why Other Options Are Wrong:(b) denies the clear price mechanism; (c)/(d) conflict with the given premises; “None” is unnecessary.Common Pitfalls:Ignoring other determinants (elasticities, hedging, imported inputs) which may dampen effects. But they do not negate the basic explanatory link.Final Answer:Both A and R are true, and R correctly explains A.

Question 4

Assertion–Reason (Tournament Participation): Assertion (A): Pakistan’s national cricket team did not participate in the tournament. Reason (R): Pakistan does not have enough cricket players.

Accepted Answer

Introduction / Context:This item probes logical sufficiency of an alleged reason for a team’s non-participation. Elite national teams generally have ample players; withdrawal or absence usually stems from other reasons.Given Data / Assumptions:A: The team did not participate in a given tournament.R: The country “does not have enough cricket players.”Background: National cricket systems maintain deep player pools; shortages at the elite level are extremely unlikely.Concept / Approach:Assess each statement separately. Then decide if R plausibly explains A. Real-world non-participation is typically due to scheduling conflicts, diplomatic/administrative issues, security concerns, sanctions, or qualification criteria—not a lack of players.Step-by-Step Solution:1) Treat A as a premise that could be true for a specific event.2) R posits an implausible cause; national sides have abundant players from domestic circuits.3) Hence, even if A is true for that event, R is false as a general explanatory claim. Therefore the correct pattern is: A true, R false.Verification / Alternative check:Historical cases of withdrawal or absence cite eligibility, logistics, politics, security, or administrative reasons—not inability to field a squad.Why Other Options Are Wrong:(a) and (b) assume R is true; (d) flips the truth values; “None” is unnecessary.Common Pitfalls:Accepting any post-hoc reason as plausible without checking domain realities (depth charts, domestic leagues).Final Answer:(A) is true, but (R) is false.

Question 5

Assertion–Reason (Jobs and Competition): Assertion (A): Rajeev has to work really hard to get a job after his graduation. Reason (R): There is a lot of competition for jobs.

Accepted Answer

Introduction / Context:The question explores labor-market reasoning: individual effort required to secure employment tends to increase with competition for limited openings.Given Data / Assumptions:A: Rajeev must work very hard to obtain a job after graduation.R: Job markets are highly competitive.Assumed ceteris paribus: number of applicants per vacancy is high; employers screen rigorously.Concept / Approach:Establish whether A and R are true in general situations and assess if R explains A. Competitive labor markets raise hiring thresholds, increasing the need for preparation, upskilling, and persistence.Step-by-Step Solution:1) R is credible: Many sectors have many applicants per role.2) A follows: Under high competition, candidates must differentiate via skills, projects, internships, and interview readiness—hence “working hard.”3) Explanation sufficiency: High competition directly raises standards, explaining Rajeev’s need for greater effort.Verification / Alternative check:Hiring funnels show steep attrition; strong portfolios, certifications, and practice can materially improve outcomes, aligning with the explanation.Why Other Options Are Wrong:(b) denies causality though it exists; (c)/(d) misstate truths; “None” is unnecessary.Common Pitfalls:Ignoring other factors (networking, location, macro cycles). These modulate but do not negate the core explanation based on competition.Final Answer:Both A and R are true, and R correctly explains A.

Question 6

Assertion–Reason (Restaurant Crowds): Assertion (A): The Eatlo Restaurant is always filled to capacity. Reason (R): The Eatlo Restaurant serves food at a very low price.

Accepted Answer

Introduction / Context:This problem checks understanding of demand drivers in consumer markets. Restaurant footfall responds to price, quality, location, service speed, ambiance, and word-of-mouth. The claim is that consistently low pricing explains consistently high occupancy.Given Data / Assumptions:A: The restaurant is always full.R: The restaurant charges very low prices.Assume quality is adequate so that low price does not deter repeat customers.Concept / Approach:Price elasticity of demand suggests that lowering price (ceteris paribus) increases quantity demanded. If capacity is limited, persistent excess demand can manifest as “always full.” We must test the truth of A and R and whether R causally explains A.Step-by-Step Solution:1) R is plausible and taken as true in the stem.2) A states an observed outcome: full capacity utilization.3) Link: Low prices reduce the customer’s cost, attracting larger crowds; if the restaurant faces capacity constraints and steady inflow, occupancy remains at or near 100%. Hence R explains A.Verification / Alternative check:Queueing and yield-management logic: sustained low pricing + adequate quality + good location can create daily peak queues, consistent with “always full.”Why Other Options Are Wrong:(b) denies the causal channel; (c)/(d) contradict the premises; “None” adds no value.Common Pitfalls:Assuming price is the only factor. While not the sole driver, it can suffice to explain full capacity if the other basics are satisfactory.Final Answer:Both A and R are true, and R correctly explains A.

Question 7

Assertion–Reason (Opposite Seasons by Hemisphere): Assertion (A): In December, Britain has winter while Australia has summer. Reason (R): Australia is located in the Southern Hemisphere.

Accepted Answer

Introduction / Context:This Assertion–Reason item tests basic Earth–Sun geometry and the climatic consequence of hemispheric tilt. Learners must judge the truth of both statements and then evaluate whether the Reason causally explains the Assertion.Given Data / Assumptions:A: December brings winter to Britain and summer to Australia.R: Australia lies in the Southern Hemisphere.Earth’s axis is tilted (~23.5 degrees) relative to its orbital plane; seasons arise from changing solar declination, not from Earth–Sun distance.Concept / Approach:The hemisphere tilted toward the Sun receives higher solar altitude and longer daylight, producing summer conditions. The opposite hemisphere has lower solar altitude, shorter days, and thus winter.Step-by-Step Solution:1) Truth of A: Britain is in the Northern Hemisphere; December is boreal winter. Australia is in the Southern Hemisphere; December is austral summer. So A is true.2) Truth of R: Australia is unequivocally south of the equator; R is true.3) Explanatory link: The hemispheric location (Southern vs Northern) combined with axial tilt directly explains the opposite seasons observed in December. Hence R correctly explains A.Verification / Alternative check:Check solstice dates: Around December 21–22 is the Southern Hemisphere’s summer solstice and the Northern Hemisphere’s winter solstice, matching the assertion.Why Other Options Are Wrong:(b) denies the correct explanation; (c) incorrectly calls R false; (d) wrongly negates A; “None” is unnecessary.Common Pitfalls:Attributing seasons to Earth–Sun distance (perihelion/aphelion) rather than axial tilt and solar angle/day length.Final Answer:Both A and R are true, and R correctly explains A.

Question 8

Assertion–Reason (Deliquescence vs Hydrophobicity): Assertion (A): Common salt readily adsorbs moisture from the atmosphere. Reason (R): Salts are hydrophobic.

Accepted Answer

Introduction / Context:This item distinguishes between hygroscopic/deliquescent behavior and hydrophobicity. It checks whether the stated reason matches the surface-chemistry phenomenon described in the assertion.Given Data / Assumptions:A: “Common salt” (typically NaCl; mixtures may include MgCl2, CaCl2, etc.) tends to pick up moisture in humid air.R: “Salts are hydrophobic.”Definitions: Hygroscopic substances attract water molecules; deliquescent substances absorb so much water that they dissolve. Hydrophobic substances repel water.Concept / Approach:Many ionic salts are hygroscopic or deliquescent, especially chlorides like CaCl2 and MgCl2. Table salt can cake in humid conditions due to impurities or accompanying anti-caking agents; the moisture affinity is hydrophilic, not hydrophobic.Step-by-Step Solution:1) A is substantially true in everyday observation: salt tends to clump by absorbing atmospheric moisture.2) R claims salts are hydrophobic. This is false: ionic solids are generally hydrophilic; some are strongly hygroscopic/deliquescent.3) Therefore the correct relationship is: A true, R false.Verification / Alternative check:Common desiccants include CaCl2 and silica gel; the former is a salt that actively absorbs moisture, confirming hydrophilicity.Why Other Options Are Wrong:(a)/(b) require R to be true; (d) inverts truth values; “None” is unnecessary.Common Pitfalls:Confusing “oily/hydrophobic” behavior with ionic solids; assuming NaCl itself is strongly deliquescent (it is mildly hygroscopic, but table salt caking often involves other salts/impurities).Final Answer:(A) is true, but (R) is false.

Question 9

Assertion–Reason (Universal Adult Franchise vs Freedom Movement Participation): Assertion (A): Our Constitution grants equal voting rights to all citizens. Reason (R): In our freedom movement, all the people participated equally.

Accepted Answer

Introduction / Context:The question probes constitutional civics and causal reasoning. Universal adult franchise is a normative constitutional choice. The Reason appeals to a historical claim about equal participation in the freedom movement, which must be evaluated independently.Given Data / Assumptions:A: Equal voting rights (universal adult suffrage) are guaranteed to all citizens.R: The freedom struggle witnessed equal participation by “all the people.”Constitutional design reflected commitments to equality and democratic representation post-independence.Concept / Approach:Truth-test each statement. A is correct (universal adult franchise, subject to legal age and disqualifications). R is historically overstated: participation varied by region, class, gender, caste, and circumstance—far from literally “equal.” Then evaluate explanation linkage.Step-by-Step Solution:1) A is true: equal vote is a foundational principle of the Constitution.2) R is false in literal terms: activism and risks were unevenly borne; not everyone participated equally.3) Even if some broad-based participation existed, it is not the definitive constitutional rationale; equality before the law and democratic ideals underpin suffrage. Hence the correct pattern is A true, R false.Verification / Alternative check:Review constitutional provisions on adult suffrage and historical scholarship on the diversity and unevenness of movement participation.Why Other Options Are Wrong:(a)/(b) require R to be true; (d) denies A; “None” is redundant.Common Pitfalls:Reading “equal” normatively rather than literally; conflating inspirational rhetoric with factual equality of participation.Final Answer:(A) is true, but (R) is false.

Question 10

Assertion–Reason (Marketing Maxim vs Loyalty): Assertion (A): Customer is king. Reason (R): Customers are loyal.

Accepted Answer

Introduction / Context:This item contrasts a normative marketing principle with an empirical claim about buyer behavior. The test is whether a slogan-like assertion is rendered true by a generalization about loyalty.Given Data / Assumptions:A: “Customer is king” — a maxim indicating firms should prioritize customer value, satisfaction, and experience.R: “Customers are loyal” — a broad claim that most customers consistently repurchase the same brand/vendor.Market realities: loyalty varies by category, switching costs, differentiation, price sensitivity, and alternatives.Concept / Approach:Evaluate A and R. “Customer is king” is widely accepted as a guiding principle for market orientation; treat it as a true normative assertion within business studies. R, however, is not universally true; loyalty is contingent and often limited, especially where products are commoditized or switching is easy.Step-by-Step Solution:1) A is accepted as a true guiding principle for customer-centric strategy.2) R is false in generality: many customers are opportunistic, price-sensitive, or multi-homing; loyalty programs exist precisely because loyalty cannot be assumed.3) Therefore the correct relationship is: A true, R false.Verification / Alternative check:Consider categories like ride-hailing, groceries, or telecom where churn is meaningful; loyalty requires deliberate retention tactics.Why Other Options Are Wrong:(a)/(b) misjudge R as true; (d) wrongly negates A; “None” is unnecessary.Common Pitfalls:Confusing desired behavior (loyalty) with observed behavior; mistaking a slogan’s prescriptive tone for a descriptive explanation.Final Answer:(A) is true, but (R) is false.

Question 11

Assertion–Reason (Common Cold and Drug Resistance): Assertion (A): There are no medicines to cure the common cold. Reason (R): Over time, disease-causing bacteria and viruses become drug resistant.

Accepted Answer

Introduction / Context:This item checks understanding of why the “common cold” (typically viral, e.g., rhinoviruses) lacks a specific curative drug in routine practice and clarifies misconceptions involving antibiotic resistance.Given Data / Assumptions:A: No medicines cure the common cold outright; management is generally symptomatic (rest, fluids, analgesics, decongestants).R: Pathogens become drug resistant over time, implying resistance explains the lack of a cure.Note: Antibiotics target bacteria, not viruses; cold is viral. Antivirals for common cold are limited and not used as universal cures.Concept / Approach:Evaluate truth of A and R separately, then the explanatory link. The absence of a simple cure is due to virological diversity, rapid antigenic variation, self-limiting natural history, and limited cost–benefit of developing broad antivirals—not primarily because of resistance.Step-by-Step Solution:1) A: In standard clinical advice, no single curative medicine eradicates the common cold; supportive therapy is recommended. So A is true.2) R: While drug resistance is a real phenomenon (notably in bacteria; also in some viruses like HIV/flu), it is not the reason we lack a cure for the common cold. Thus, as an explanation for A, R is false.3) Relation: A true, R false.Verification / Alternative check:Public health guidance emphasizes prevention (hand hygiene) and symptomatic relief; antibiotics are ineffective against cold viruses and are discouraged.Why Other Options Are Wrong:(a)/(b) require R to be true; (d) flips truth values; “None” is redundant.Common Pitfalls:Assuming any infection without a cure must be due to resistance; confusing bacterial with viral pathogens; overgeneralizing antivirals.Final Answer:(A) is true, but (R) is false.

Question 12

Assertion (A): Large commercial vehicles passing through a city cause pollution and are required to pay entry tax. Reason (R): Money is needed to clean the environment.

Accepted Answer

Money is levied to discourage commercial vehicles to enter the city .

Question 13

Assertion (A): Mars is very close to the Sun. Reason (R): Smaller planets revolve closer to the Sun.

Accepted Answer

Both are factually wrong. Mars is farther from the Sun than the Earth and is also smaller than the Earth and is also smaller than Earth.

Question 14

Assertion (A): Cacti are fleshy plants and have small leaves. Reason (R): Deserts witness sporadic

Accepted Answer

Because of the sporadic rains, the cacti conserve water.

Question 15

Assertion (A): Per hectare yields of most crops in India is very low, compared to that of many other countries. Reason (R): Most of the farmers in India are illiterate.

Accepted Answer

The yield is low because of many reasons such as old agriculture technique, absence of good quality inputs and so on.

Question 16

Assertion (A): e-commerce in India is growing at a rapid pace. Reason (R): India has a large number of young entrepreneurs with education from premier educational institutes.

Accepted Answer

Young entrepreneurs can take up any business but they will adopt e-commerce because it has high demand .

Question 17

Assertion–Reason (Evaluate Truth and Explanation): Assertion (A): Alok bought a big car and will need a lot of petrol to run. Reason (R): All cars need petrol to run. Choose the correct option about the truth of (A) and (R) and whether (R) explains …

Accepted Answer

Introduction / Context:This is a classic Assertion–Reason item. We must independently test the truth of (A) and (R), and then check whether (R) explains (A).Given Data / Assumptions:(A) Big car → “will need a lot of petrol.” Read “petrol” colloquially as “fuel”; bigger/heavier cars typically have lower mileage and hence higher fuel consumption.(R) “All cars need petrol” states a universal claim.Concept / Approach:Evaluate truth values first, then explanatory link. A universal generalization fails if any counterexample exists.Step-by-Step Solution:1) (A): Larger displacement/weight often implies higher fuel usage → broadly true as a general tendency.2) (R): Not all cars run on petrol (diesel, CNG, electric, hybrid). So the universal “all” is false.3) Since (R) is false, it cannot be the correct explanation of (A).Verification / Alternative check:Even if we interpret “petrol” as “fuel,” (R) remains false due to EVs and diesel vehicles.Why Other Options Are Wrong:Options (a) and (b) require (R) to be true; it is not. (d) and (e) misjudge (A), which is generally acceptable as a tendency.Common Pitfalls:Confusing colloquial “petrol” with “fuel” and accepting a universal statement without checking counterexamples.Final Answer:Option C: (A) true, (R) false.

Question 18

Assertion–Reason (Evaluate Truth and Explanation): Assertion (A): Bread that develops mould on it has to be thrown away. Reason (R): All moulds are poisonous.

Accepted Answer

Introduction / Context:Food safety questions often hinge on conservative practice versus over-generalized reasons. We must assess both statements independently and the explanatory link.Given Data / Assumptions:(A) Advises discarding mouldy bread.(R) Claims all moulds are poisonous.Concept / Approach:Even if not every mould produces dangerous mycotoxins, porous foods like bread allow hyphae/mycelium to spread beyond visible patches, making discarding prudent.Step-by-Step Solution:1) (A) is sound: for soft/porous foods, safe practice is to discard when mould is present.2) (R) is false because “all moulds are poisonous” is an overstatement; toxicity varies by species/conditions.3) Therefore, (R) cannot be the correct explanation of (A).Verification / Alternative check:The reason to discard is risk of invisible spread and potential toxins, not that all moulds are poisonous.Why Other Options Are Wrong:(a) and (b) require (R) true; (d) flips truth values; (e) denies established food-safety advice.Common Pitfalls:Accepting universal claims without exceptions; assuming visible mould equals the entire contaminated region.Final Answer:Option C: (A) true, (R) false.

Question 19

Assertion–Reason (Evaluate Truth and Explanation): Assertion (A): People are scared of snakes and whenever they see any snake, they kill it. Reason (R): All snakes are poisonous and can kill a person by injecting poison through fangs.

Accepted Answer

Introduction / Context:The stem contains two sweeping generalizations—about human behavior and snake biology. We must test them for universality.Given Data / Assumptions:(A) claims everyone kills any snake on sight.(R) claims all snakes are deadly venomous with killing capability via fangs.Concept / Approach:Universal statements fail with counterexamples. Many humans do not kill snakes; many snakes are non-venomous.Step-by-Step Solution:1) (A) is false: people’s responses vary (avoidance, rescue calls, relocation), not universal killing.2) (R) is false: numerous species are non-venomous; even many venomous bites are not inevitably fatal.3) With both false, (R) cannot explain (A).Verification / Alternative check:Conservation and herpetology practice emphasize identification and non-lethal responses, contradicting (A); global snake diversity contradicts (R).Why Other Options Are Wrong:They presume truth of either (A) or (R), which is unjustified.Common Pitfalls:Accepting fear-based or media-based overgeneralizations.Final Answer:Option E: Both (A) and (R) are false.

Question 20

Assertion–Reason (Evaluate Truth and Explanation): Assertion (A): The average temperature of the Earth has been rising. Reason (R): The greenhouse effect traps the Sun’s heat within the Earth’s atmosphere.

Accepted Answer

Introduction / Context:This item links observed global warming to the greenhouse effect, a foundational climate concept.Given Data / Assumptions:(A) Multidecadal trend: rising global mean surface temperature.(R) Greenhouse gases absorb and re-emit infrared radiation, trapping heat.Concept / Approach:The enhanced greenhouse effect, due to increased greenhouse gas concentrations, explains observed warming.Step-by-Step Solution:1) (A) True: long-term upward trend in global average temperature is well-documented.2) (R) True: greenhouse effect is a real physical mechanism.3) (R) causally explains (A): enhanced greenhouse forcing raises equilibrium temperatures.Verification / Alternative check:Short-term variability (e.g., ENSO) does not negate the long-term trend or the forcing mechanism.Why Other Options Are Wrong:They deny either the observation, the mechanism, or their causal connection.Common Pitfalls:Confusing weather variability with climate trends; ignoring radiative forcing basics.Final Answer:Option A: Both true; (R) correctly explains (A).
