Question 1

Entering a room: Arrange the following actions in a logical order from access to switching on the light. 1. Key 2. Door 3. Lock 4. Room 5. Switch on

Accepted Answer

Introduction / Context:This sequencing problem captures a simple, everyday action: entering a room and turning on the light. Correct ordering relies on cause-and-effect and the physical constraints of locks and doors.Given Data / Assumptions:You possess a Key.There is a Lock on the Door.You want to enter the Room and then Switch on the light.Concept / Approach:Access requires unlocking before opening. You cannot interact with the room interior or switch until you have entered. Therefore, unlocking precedes opening; entry precedes switching on.Step-by-Step Solution:Use Key (1) to operate the Lock (3).Open the Door (2) after it is unlocked.Enter the Room (4).Switch on (5) the light inside the room.Verification / Alternative check:Consider impossibility checks: you cannot open a locked door, and you cannot switch on the light before entering if the switch is inside.Why Other Options Are Wrong:1, 2, 3, 5, 4: Opens the door before unlocking; then tries to switch before entering.4, 2, 1, 5, 3: Begins inside the room; illogical.5, 1, 2, 4, 3: Switching on before entry; also leaves the door locked at the end.Common Pitfalls:Overlooking the lock–door dependency or assuming external switches. The safest generic assumption is the switch is accessible after entry.Final Answer:1, 3, 2, 4, 5

Question 2

Logical ordering – administrative geography hierarchy Arrange the following administrative/geographical units from the smallest/local to the largest/broader level:  District 2. Village 3. State 4. Town 5. City

Accepted Answer

Introduction / Context:This is a sequencing question about Indian administrative and settlement hierarchy. To order items correctly, think from the smallest day-to-day habitation up to the broadest political unit that governs many smaller units.Given Data / Assumptions:Units to arrange: Village, Town, City, District, State.Interpret “meaningful sequence” as increasing scale from local to larger jurisdiction.City and Town are urban settlements; District is an administrative unit comprising many settlements; State is the largest among the given choices.Concept / Approach:Begin with the smallest settlement type and move outward to containers that include it. Villages and towns/cities are contained within districts; districts are contained within states.Step-by-Step Solution:Village is the smallest everyday settlement: choose 2 earliest.Between Town and City, a Town is typically smaller than a City: place 4 before 5.A District is an administrative area that includes multiple towns and cities: place 1 after 5.A State is the broader political unit comprising many districts: place 3 last.Final order: 2, 4, 5, 1, 3.Verification / Alternative check:Check containment: villages Why Other Options Are Wrong:2, 1, 4, 5, 3: Puts District before Town/City, breaking the nesting.5, 3, 2, 1, 4 and 2, 5, 3, 4, 1: Mix unrelated scales; State cannot precede District when moving from small to large.2, 4, 1, 5, 3: Places District before City; a city lies within a district.Common Pitfalls:Confusing administrative units (District, State) with settlement types (Village, Town, City) and forgetting the containment rule.Final Answer:2, 4, 5, 1, 3

Question 3

Logical ordering – cause to effect for a rainbow Arrange the following to represent a realistic cause-effect chain leading to a child’s happiness on seeing a rainbow:  Rainbow 2. Rain 3. Sun 4. Happy 5. Child

Accepted Answer

Introduction / Context:This sequencing problem asks you to align natural causes and human reactions. A rainbow needs specific weather and light conditions, and then a child reacts emotionally after seeing it.Given Data / Assumptions:A rainbow forms when sunlight and raindrops interact.“Child” is the observer; “Happy” is the emotional effect.We must go from physical causes to human outcome.Concept / Approach:The physics: sunlight enters raindrops, refracts, reflects internally, and disperses, creating a rainbow visible to an observer. The psychology: the child sees it and feels happy.Step-by-Step Solution:Begin with Rain (2), a prerequisite medium.Add Sun (3), whose light is needed to form the rainbow.These produce Rainbow (1) via optical effects.The Child (5) observes the rainbow.The observation leads to the feeling Happy (4).Verification / Alternative check:Ask: can a rainbow exist without rain or sun? No. Does happiness precede the sighting? No. The order is therefore consistent with real-world causality.Why Other Options Are Wrong:2, 1, 4, 3, 5: Places happiness and rainbow before sunlight.4, 2, 3, 5, 1 or 4, 5, 1, 2, 3: Start with emotions, not causes.Common Pitfalls:Mixing observer and emotion before the natural event forms; forgetting the sun is essential even during rain.Final Answer:2, 3, 1, 5, 4

Question 4

Logical ordering – human body parts from head to toe Arrange the following body parts in correct anatomical order from top (head) to bottom (feet):  Heel 2. Shoulder 3. Skull 4. Neck 5. Knee 6. Chest 7. Thigh 8. Stomach 9. Face 10. Hand

Accepted Answer

Introduction / Context:This arrangement problem relies on basic human anatomy. The task is to place listed parts in a strict vertical order from the head region down to the feet.Given Data / Assumptions:The sequence should follow a general top-to-bottom orientation for an upright human.Arms (hands) hang from shoulders and are generally above the abdomen and legs in vertical reference.List contains: skull, face, neck, shoulder, hand, chest, stomach, thigh, knee, heel.Concept / Approach:Start at the head and proceed downward, placing each item where it anatomically belongs along the vertical axis, allowing that hands attach at shoulder level and usually hang around torso height but are considered with the upper limb after shoulders.Step-by-Step Solution:Topmost structures: Skull (3) then Face (9).Below the face is the Neck (4).Next at the upper torso: Shoulder (2), then Hand (10) as an upper-limb part associated with the shoulder girdle.Torso order: Chest (6) above Stomach (8).Lower limb: Thigh (7) above Knee (5) above Heel (1) at the foot.Thus: 3, 9, 4, 2, 10, 6, 8, 7, 5, 1.Verification / Alternative check:Trace from head to foot; each subsequent item appears physically lower than the previous, satisfying the directional rule.Why Other Options Are Wrong:Lists that place heel or knee above torso parts violate anatomy.Sequences that position hand below abdomen or legs disrupt the upper-limb relationship to the shoulder.Common Pitfalls:Confusing the hand’s vertical placement relative to torso and legs; mixing facial parts before skull or after neck.Final Answer:3, 9, 4, 2, 10, 6, 8, 7, 5, 1

Question 5

Logical ordering – from procurement to prepared dish Arrange the following steps of making a dish in the most realistic order:  Cutting 2. Dish 3. Vegetable 4. Market 5. Cooking

Accepted Answer

Introduction / Context:This sequencing problem mirrors a real-life cooking workflow, from acquiring ingredients to serving the finished item.Given Data / Assumptions:“Market” implies procurement of raw vegetables.“Cutting” happens before heat is applied in “Cooking”.The final “Dish” is the outcome.Concept / Approach:Follow the culinary pipeline: source ingredients, process them, apply heat, then present the dish. Each step should logically enable the next.Step-by-Step Solution:Go to Market (4) to purchase raw vegetables.Obtain the Vegetable (3) as the input for preparation.Perform Cutting (1) to prepare for cooking.Do the Cooking (5) to transform ingredients.Result is the Dish (2) ready to serve.Verification / Alternative check:Check feasibility: you cannot cut or cook before acquiring ingredients; the sequence matches common kitchen practice.Why Other Options Are Wrong:Any order placing Dish before Cooking is impossible.Cutting after Cooking is atypical for vegetables.Common Pitfalls:Confusing procurement with processing or skipping cutting before cooking certain recipes.Final Answer:4, 3, 1, 5, 2

Question 6

Logical ordering – animals from smallest to largest (general body size) Arrange the following animals in increasing order of typical size:  Elephant 2. Cat 3. Mosquito 4. Tiger 5. Whale

Accepted Answer

Introduction / Context:Ordering by size requires broad real-world knowledge of animal biology. We use typical adult sizes, not exceptional individuals.Given Data / Assumptions:Mosquito is a tiny insect; Cat is a small mammal.Tiger is a large feline; Elephant is a large terrestrial mammal.Whale (e.g., blue whale) is the largest animal on Earth.Concept / Approach:Move from the smallest organism to the largest by comparing typical body length/mass ranges for adults of each species group.Step-by-Step Solution:Start with Mosquito (3) as the smallest.Next is Cat (2), a small domestic mammal.Tiger (4) exceeds cats by orders of magnitude.Elephant (1) is larger than big cats, among the largest land animals.Whale (5) is the largest overall, topping the list.Verification / Alternative check:Compare average adult masses: milligrams (mosquito) Why Other Options Are Wrong:Any order placing elephant before tiger and after whale incorrectly treats sizes.Sequences with mosquito not first or whale not last contradict obvious size extremes.Common Pitfalls:Confusing individual extremes (e.g., small tigers vs. large cats) rather than typical adult sizes.Final Answer:3, 2, 4, 1, 5

Question 7

Logical ordering – steps in garment making and wearing Arrange the following actions in the correct workflow to get a garment ready to wear:  Cut 2. Put on 3. Mark 4. Measure 5. Tailor (stitch)

Accepted Answer

Introduction / Context:This sequence mirrors a tailoring pipeline. Think like a professional tailor: measure first, prepare marks, cut fabric, stitch, and then the customer wears the garment.Given Data / Assumptions:“Tailor” here represents the stitching/assembly step performed by a tailor.“Put on” is the final wearing of the finished garment.Marks guide accurate cutting after measurements.Concept / Approach:Each step should enable the next without rework: measuring defines dimensions, marking translates dimensions to fabric, cutting creates pieces, tailoring stitches them, and wearing comes last.Step-by-Step Solution:Measure (4): obtain body dimensions.Mark (3): transfer measurements to fabric layout.Cut (1): cut fabric along the marks.Tailor/Stitch (5): assemble the pieces.Put on (2): wear the finished garment.Verification / Alternative check:Try swapping any two adjacent steps: doing so breaks the workflow (e.g., cutting before marking risks errors).Why Other Options Are Wrong:Starting with Put on (2) is impossible without a stitched garment.Cutting before measuring/marking leads to wrong sizing.Common Pitfalls:Mistaking “Tailor” as the professional rather than the stitching step; ignoring the vital marking stage between measuring and cutting.Final Answer:4, 3, 1, 5, 2

Question 8

Logical ordering – cotton to finished saree (production process) Arrange the following in the correct order to show how cotton becomes a saree:  Yarn 2. Plant 3. Saree 4. Cotton 5. Cloth

Accepted Answer

Introduction / Context:Textile production follows a clear chain from agriculture to finished garment. Recognizing each transformation step is a common reasoning skill in manufacturing-process questions.Given Data / Assumptions:Cotton originates from a Plant.Raw cotton is spun into Yarn.Yarn is woven/knitted into Cloth.Cloth is tailored into a Saree (finished apparel).Concept / Approach:Express the pathway as a series of value-added conversions: biological source → raw fiber → intermediate thread → fabric → apparel.Step-by-Step Solution:Start with Plant (2) that produces cotton bolls.Harvest Cotton (4) as raw fiber.Spin into Yarn (1) through ginning and spinning processes.Weave/knit into Cloth (5) on looms.Cut/stitch or drape to form the final Saree (3).Verification / Alternative check:Each step depends on the previous output; reversing any step makes production infeasible.Why Other Options Are Wrong:Any sequence putting Saree before Cloth, or Yarn after Cloth, contradicts standard textile manufacture.Common Pitfalls:Confusing Cloth and Yarn order; forgetting that all fabric begins as yarn made from fibers.Final Answer:2, 4, 1, 5, 3

Question 9

Logical ordering – criminal justice pathway Arrange the following in a realistic order representing how society responds to crime:  Police 2. Punishment 3. Crime 4. Justice 5. Judgement

Accepted Answer

Introduction / Context:This sequencing question models the typical criminal-justice pipeline from an unlawful act through institutional response to societal justice. Understanding the order helps in civics, law basics, and reasoning tests.Given Data / Assumptions:Crime happens first, prompting state action.Police respond with investigation and charge.Court issues Judgement; if guilty, Punishment follows.Justice is the broader social outcome achieved by due process.Concept / Approach:We must respect due process: act → investigation → adjudication → sentencing → social justice. “Justice” is not a procedural step but the end state resulting from correct judgement and proportionate punishment.Step-by-Step Solution:Crime (3) occurs.Police (1) investigate and frame charges.Judgement (5) is delivered by the court after trial.Punishment (2) is imposed based on the judgement when applicable.Justice (4) is thereby served as an outcome of the lawful process.Verification / Alternative check:Swap any two consecutive steps to test plausibility: punishment cannot precede judgement; police cannot act before a crime is alleged; justice cannot meaningfully precede adjudication.Why Other Options Are Wrong:1, 2, 3, 4, 5: Begins with Police before any crime—illogical.3, 1, 2, 4, 5: Moves to punishment before judgement.5, 4, 3, 2, 1: Entirely reversed and mixes abstract “justice” with procedures.Common Pitfalls:Confusing “justice” (an outcome) with “judgement” (a court decision); assuming punishment can occur without a verdict.Final Answer:3, 1, 5, 2, 4

Question 10

Logical ordering – patient journey in healthcare Arrange the following stages as they typically occur for a patient seeking medical care:  Patient 2. Diagnosis 3. Bill 4. Doctor 5. Treatment

Accepted Answer

Introduction / Context:Healthcare reasoning problems ask you to reconstruct the typical flow from patient arrival to final billing. This mirrors real-world clinic or hospital processes.Given Data / Assumptions:The patient seeks medical help.The doctor examines and orders tests to reach a diagnosis.Treatment is given after diagnosis.Billing is usually prepared after treatment is decided or delivered.Concept / Approach:Follow clinical logic rather than administrative anomalies. Diagnosis precedes treatment; billing is the administrative end step.Step-by-Step Solution:Patient (1) arrives seeking care.Doctor (4) conducts examination and investigations.Diagnosis (2) is established from findings.Treatment (5) is planned and administered based on diagnosis.Bill (3) is generated for services rendered.Verification / Alternative check:In almost all clinical settings, treatment is not started before a working diagnosis. Administrative billing trails medical management.Why Other Options Are Wrong:Placing Bill before Diagnosis/Treatment ignores normal hospital workflow.Starting with Doctor instead of Patient reverses the first contact.Common Pitfalls:Confusing triage/admin registration steps with the core medical pathway; thinking that billing can precede clinical decision-making.Final Answer:1, 4, 2, 5, 3

Question 11

Logical ordering – place hierarchy from local to cosmic scale Arrange the following locations from the most specific to the most expansive:  Andhra Pradesh 2. Universe 3. Tirupati 4. World 5. India

Accepted Answer

Introduction / Context:This hierarchy question spans geography from a specific city to the entire Universe. The goal is to nest each location within its next larger container.Given Data / Assumptions:Tirupati is a city in Andhra Pradesh (a state of India).India is a nation within the World (Earth).The Universe is the broadest scale, containing everything.Concept / Approach:Apply strict containment: city → state → country → world → universe.Step-by-Step Solution:Start with Tirupati (3), the city.Place Andhra Pradesh (1), the containing state, next.Then India (5), the country containing that state.Next is the World (4), i.e., planet Earth.Finally, the Universe (2), which encompasses all space and matter.Verification / Alternative check:Each item is geographically or cosmologically contained by the next, with no violations in the nesting logic.Why Other Options Are Wrong:Any choice placing World or Universe before India breaks containment.Sequences that do not move from local to broader scales are inconsistent with geography.Common Pitfalls:Starting from a large scale (Universe) and moving down without consistent nesting; misplacing state vs. country.Final Answer:3, 1, 5, 4, 2

Question 12

Logical ordering — Career path progression Arrange the following stages in a realistic, meaningful sequence for a typical job-seeking journey:  Study  Job  Examination  Earn (salary/income)  Apply (for positions)

Accepted Answer

Introduction / Context:This sequencing question tests everyday reasoning about how a person typically moves from learning to earning. Ordering life or career events demands clarity about dependencies (what must happen before something else) and the usual hiring pipeline.Given Data / Assumptions:Stages: Study, Examination, Apply, Job, Earn.We assume a standard scenario: formal study precedes qualifying examinations; applications precede a job offer; income starts after joining.We are arranging the list from first to last in a typical order.Concept / Approach:Use cause–effect and prerequisite logic. Skill/knowledge acquisition leads to evaluation, which enables candidacy. Only after applying and being selected does employment begin, followed by salary.Step-by-Step Solution:Study builds knowledge and eligibility → choose 1 first.Evaluation/qualifying test typically follows study → 3 next.With results/credentials in hand, candidates apply → 5 next.Successful application leads to a job offer/joining → 2 next.Once in the job, earnings begin → 4 last.Verification / Alternative check:Reverse-check dependencies: one cannot earn without a job; one cannot obtain most jobs without applying; one typically applies after meeting examination-based eligibility that follows study. The chain is therefore consistent.Why Other Options Are Wrong:1, 2, 3, 4, 5: Puts job before examination and application, which breaks prerequisites.1, 3, 5, 4, 2: Puts earning before job, which is illogical.1, 3, 2, 5, 4: Places job before application.1, 2, 5, 3, 4: Multiple prerequisite violations (job before apply/exam).Common Pitfalls:Forgetting that application typically follows exam/qualification, and that income begins only after the job starts, not at the offer stage.Final Answer:1, 3, 5, 2, 4

Question 13

Historical development — Human technology ages Arrange the following eras into a meaningful chronological sequence (from earliest to latest):  Atomic Age  Metallic Age  Stone Age  Alloy Age

Accepted Answer

Introduction / Context:The question assesses knowledge of broad technological phases in human history. While labels can vary in scope, there is a widely accepted sequence from primitive stone tools to advanced metallurgy and, finally, the nuclear/atomic era.Given Data / Assumptions:Stone Age denotes earliest extensive tool use with stone implements.Metallic Age indicates the historical move to metals (e.g., copper, bronze, iron).Alloy Age represents deliberate alloy-making maturity (beyond simple metals).Atomic Age follows the advent of nuclear science and technology in the 20th century.Concept / Approach:Place eras by technological capability: stone → metal → alloy specialization → atomic technology. The leap to nuclear science is the most recent.Step-by-Step Solution:Earliest is Stone Age → 3.Then societal mastery of metals → Metallic Age → 2.Refinement into alloy engineering → Alloy Age → 4.Modern nuclear era → Atomic Age → 1.Verification / Alternative check:Cross-check with common chronology: Paleolithic/Neolithic predate Bronze/Iron, which precede contemporary atomic developments. The ordered list matches this logic.Why Other Options Are Wrong:1, 3, 4, 2 and 2, 3, 1, 4: Place the Atomic Age before ancient periods, which is impossible.4, 3, 2, 1: Begins with alloys before stone, anachronistic.3, 2, 1, 4: Puts Atomic before Alloy, against technological progression.Common Pitfalls:Confusing ”metal” and ”alloy” stages, or assuming the Atomic Age refers to general electricity use. It specifically denotes nuclear-era advances.Final Answer:3, 2, 4, 1

Question 14

Production chain — From forest to book Arrange the following in a meaningful production sequence:  Book  Pulp  Timber  Jungle (forest)  Paper

Accepted Answer

Introduction / Context:This ordering problem follows the resource-to-product pipeline in publishing. Understanding how raw materials become finished goods is a common test of practical reasoning.Given Data / Assumptions:Forest (jungle) provides raw wood.Timber (processed wood) is converted to pulp.Pulp is processed into paper.Paper is used to produce books.Concept / Approach:Track the physical transformation from raw natural resource to final consumer product. Each stage depends on the output of the previous stage.Step-by-Step Solution:Start: Jungle (forest) → 4.Logs/wood become Timber → 3.Timber is chemically/mechanically processed to Pulp → 2.Pulp is made into Paper → 5.Paper becomes the Book → 1.Verification / Alternative check:Each step is a standard industrial stage; reversing any two adjacent steps would break the manufacturing logic.Why Other Options Are Wrong:Any sequence starting with Pulp or Timber ignores their raw source (forest).Placing Book before Paper or Pulp is impossible.Common Pitfalls:Confusing ”timber” and ”pulp” order, or thinking paper precedes pulp.Final Answer:4, 3, 2, 5, 1

Question 15

Text structure hierarchy — Book to letter Arrange the following textual units from largest to smallest logical container:  Sentence  Chapter  Letter (character)  Book  Word  Paragraph

Accepted Answer

Introduction / Context:This sequence checks understanding of how written material is organized. A book is divided into chapters, paragraphs, sentences, words, and finally letters.Given Data / Assumptions:We arrange from largest container to smallest unit.Standard publishing structure is assumed.Concept / Approach:Consider nesting: each larger unit contains multiple instances of the smaller one. The hierarchy must preserve this containment property at every step.Step-by-Step Solution:Book is the largest container → 4 first.Books contain Chapters → 2 next.Chapters contain Paragraphs → 6 next.Paragraphs contain Sentences → 1 next.Sentences contain Words → 5 next.Words are made of Letters → 3 last.Verification / Alternative check:Try reversing any adjacent pair: doing so breaks the container relationship (e.g., words cannot contain sentences).Why Other Options Are Wrong:Any sequence where paragraph appears after sentence, or word before sentence, violates containment logic.Common Pitfalls:Mixing up paragraph and sentence positions or ignoring that letters are the smallest unit listed.Final Answer:4, 2, 6, 1, 5, 3

Question 16

Biology sequencing — Plant part development and position Arrange the following plant parts in a meaningful order reflecting growth/organ sequence:  Leaf  Fruit  Stem  Root  Flower

Accepted Answer

Introduction / Context:This question checks basic botanical reasoning—recognizing a sensible order of plant parts based on development and functional position.Given Data / Assumptions:Typical seedling/rooted plant organ progression is considered.Reproductive organs (flowers) precede fruits.Leaves arise from stems to support photosynthesis.Concept / Approach:Think from foundational support and nutrient uptake to vegetative growth and finally reproduction. Roots anchor and absorb; stems support and transport; leaves perform photosynthesis; flowers enable reproduction; fruits follow to protect and disperse seeds.Step-by-Step Solution:Root provides initial anchorage and absorption → 4 first.Stem emerges to support transport and structure → 3 next.Leaves develop on stems to photosynthesize → 1 next.Flower forms as the reproductive organ → 5 next.Fruit develops post-fertilization from the flower → 2 last.Verification / Alternative check:Any order placing fruit before flower violates plant reproductive biology. Likewise, leaves generally precede flowers in most growth cycles.Why Other Options Are Wrong:Options that put fruit before flower or stem before root ignore developmental dependencies.Common Pitfalls:Confusing spatial arrangement (root below ground) with temporal development; however, the chosen order satisfies both logic and common growth patterns.Final Answer:4, 3, 1, 5, 2

Question 17

Life and career progression — From child to salary Arrange the following stages in a realistic, meaningful order:  College  Child  Salary  School  Employment

Accepted Answer

Introduction / Context:Sequencing common life stages tests practical reasoning. Education typically precedes employment, and salary is a consequence of employment.Given Data / Assumptions:The sequence should reflect a common pathway: childhood → schooling → higher education → job → salary.We are not considering exceptional cases (e.g., entrepreneurship during school).Concept / Approach:Use precondition logic: later stages depend on completion of earlier ones. College admission follows schooling, and employment generally follows degrees or skills; salary follows employment.Step-by-Step Solution:Start with 'Child' → 2.Schooling follows → 4.Higher studies (College) → 1.Employment after college → 5.Salary is received upon employment → 3.Verification / Alternative check:Reversing any pair (e.g., salary before employment) fails commonsense constraints.Why Other Options Are Wrong:Any arrangement placing salary before employment, or college before school, breaks natural prerequisites.Common Pitfalls:Misreading salary as scholarship or allowance. In reasoning tests, salary implies income from employment.Final Answer:2, 4, 1, 5, 3

Question 18

Human life stages — Chronological order Arrange the following human life stages in a meaningful chronological sequence:  Puberty  Adulthood  Childhood  Infancy  Senescence (old age)  Adolescence

Accepted Answer

Introduction / Context:This item checks understanding of the natural progression of human development from birth to old age, including the physiological transition at puberty and the psychosocial phase of adolescence.Given Data / Assumptions:Infancy precedes childhood.Puberty is the biological transition that typically occurs within early adolescence.Adulthood follows adolescence; senescence comes last.We use a broadly accepted educational-psychology ordering.Concept / Approach:Order by age progression while acknowledging that puberty is the biological onset that is commonly nested within the broader social-developmental period called adolescence. Some syllabi list puberty first to emphasize biology, then adolescence as the wider phase.Step-by-Step Solution:Birth to toddler period → Infancy (4).Early schooling years → Childhood (3).Physiological change → Puberty (1).Broader teen development → Adolescence (6).Full maturity → Adulthood (2).Late-life decline → Senescence (5).Verification / Alternative check:Many curricula accept either [Infancy → Childhood → Adolescence → Puberty → Adulthood] or [Infancy → Childhood → Puberty → Adolescence → Adulthood] depending on whether puberty is treated as trigger or sub-phase. The provided correct choice matches one widely used exam convention.Why Other Options Are Wrong:Any option that places adulthood before adolescence or senescence before adulthood conflicts with standard developmental ordering.Common Pitfalls:Assuming puberty and adolescence are identical; the former is a biological milestone, the latter a broader period of change.Final Answer:4, 3, 1, 6, 2, 5

Question 19

Everyday causality — Mother and child sequence Arrange the following events in a realistic order after a baby becomes uncomfortable:  Mother  Child  Milk  Cry  Smile

Accepted Answer

Introduction / Context:This sequence models a common caregiving situation. Recognizing cause and effect in everyday interactions is a core logical skill tested in reasoning exams.Given Data / Assumptions:The child expresses a need (often hunger) by crying.The mother responds by offering milk.After feeding, the child is content and smiles.Concept / Approach:Track the trigger (discomfort) to response (caregiver action) to outcome (contentment). Order must reflect temporal causality.Step-by-Step Solution:Subject of the episode → Child (2).Signal of need → Cry (4).Caregiver intervenes → Mother (1).Provision of nourishment → Milk (3).Resolution/positive affect → Smile (5).Verification / Alternative check:Reverse-check: a smile is most plausible after feeding, and milk is most plausibly offered after crying is noticed.Why Other Options Are Wrong:Placing smile or milk before cry breaks causal order; placing mother after smile contradicts the intervention step.Common Pitfalls:Starting with the mother rather than the child’s signal; the child’s cry is the initiating event.Final Answer:2, 4, 1, 3, 5

Question 20

Process reasoning — Postal workflow from writing to delivery Arrange the following steps in a correct mailing sequence:  Post-box  Letter  Envelope  Delivery  Clearance (collection from post-box)

Accepted Answer

Introduction / Context:Understanding a real-world process end-to-end is a classic sequencing test. Here we track how a physical letter travels from the writer to the recipient through the postal system.Given Data / Assumptions:Letter content is written first.The letter is placed in an envelope before mailing.Posting is done via a public post-box.Clearance means the postal service collects mail from the post-box for sorting and routing.Delivery occurs after clearance and processing.Concept / Approach:The steps must satisfy temporal and operational constraints: create content → package → deposit → collect → deliver. Any sequence that places delivery before clearance contradicts postal operations.Step-by-Step Solution:Write the Letter → 2.Insert into Envelope → 3.Drop into Post-box → 1.Postal Clearance (collection from box) → 5.Final Delivery to addressee → 4.Verification / Alternative check:Ask whether each step depends on the previous: a letter must exist before it is enveloped; it must be enveloped before posting; the post must be collected before any delivery is possible.Why Other Options Are Wrong:Any option putting delivery before clearance misorders critical postal logistics.Sequences beginning with envelope before letter ignore content creation.Common Pitfalls:Confusing 'clearance' with 'customs clearance' or assuming it means final handover. Here, it specifically means collection from the post-box.Final Answer:2, 3, 1, 5, 4
