Question 17

Growth and development sequence in plants: Arrange the following from the beginning to later stages—(a) Seed, (b) Plant (seedling/young plant), (c) Flower, (d) Fruit, (e) Tree (mature plant).

Accepted Answer

Introduction / Context:This question asks you to arrange biological stages of a typical flowering plant from the earliest point (seed) to later developments (mature tree, flower, fruit). Such ordering tests basic life-science knowledge and real-world reasoning about growth and reproduction in plants.Given Data / Assumptions:Items: Seed, Plant (seedling/young plant), Flower, Fruit, Tree (mature stage).“Plant” denotes the early vegetative stage; “Tree” denotes the mature plant capable of regular reproduction.Typical angiosperm cycle: vegetative growth precedes flowering, which precedes fruiting.Concept / Approach:Use the standard biological progression: a seed germinates into a young plant; with continued growth it becomes a mature plant (tree). Reproductive phases follow maturity: flowering first, then fruiting (as fruits develop from flowers/ovaries).Step-by-Step Solution:Start with Seed → (a).Germination/seedling as Plant → (b).Maturation to Tree → (e).Reproductive onset: Flower → (c).Post-flowering product: Fruit → (d).Order: a, b, e, c, d.Verification / Alternative check:Fruits develop from flowers; flowers appear on mature plants. Therefore any order placing fruit before flower or before maturity is biologically inconsistent.Why Other Options Are Wrong:a, b, c, d, e: Puts flowering and fruiting before the plant is mature.b, c, d, e, a and a, e, d, c, b: Misplace seed and/or fruit relative to flower.None of these: Not needed because a correct sequence exists.Common Pitfalls:Confusing “plant” (seedling) with a mature “tree”; assuming fruit can precede flowering.Final Answer:a, b, e, c, d

Question 18

Book structure (front matter to back matter): Arrange these in the order they typically appear— a. Index, b. Content (table of contents), c. Title, d. Chapter, e. Introduction.

Accepted Answer

Introduction / Context:Most books follow a conventional layout from front matter to core chapters and then back matter. Knowing this order helps in quickly locating information and reflects general publishing practice.Given Data / Assumptions:Title page appears first.Introduction (or Preface/Foreword) precedes the table of contents in many exam conventions for reasoning problems.Contents (table of contents) lists chapters; chapters form the main body.Index appears at the end (back matter).Concept / Approach:Sequence standard components as readers encounter them: title page → introductory material → contents → chapters → index.Step-by-Step Solution:Title → c.Introduction → e.Contents → b.Chapter → d.Index → a.Therefore: c, e, b, d, a.Verification / Alternative check:Check any standard text; back matter such as the index is always at the end.Why Other Options Are Wrong:They misplace index or mix front matter order.Common Pitfalls:Confusing introduction with a chapter; placing index before contents.Final Answer:c, e, b, d, a

Question 19

Medical process order (causal and temporal): Arrange— a. Cure, b. Doctor, c. Disease, d. Diagnosis, e. Medicine.

Accepted Answer

Introduction / Context:This sequence models a typical patient journey from illness to recovery. Correct causal order is essential: condition → professional→ investigation → treatment → outcome.Given Data / Assumptions:Disease occurs first.Doctor is consulted, who performs/requests a diagnosis.Medicine is prescribed based on diagnosis.Outcome is cure (or recovery).Concept / Approach:Map each token to its natural place in the clinical pathway and ensure no step is skipped.Step-by-Step Solution:Disease → c.Doctor → b.Diagnosis → d.Medicine → e.Cure → a.Hence: c, b, d, e, a.Verification / Alternative check:Compare with standard care flow; the order is consistent.Why Other Options Are Wrong:They place investigation/treatment before disease or swap diagnosis with cure.Common Pitfalls:Confusing diagnosis with doctor; assuming cure precedes medicines.Final Answer:c, b, d, e, a

Question 20

Tree components (structural/biological order, root upward to reproductive): Arrange— a. Fruits, b. Roots, c. Trunks, d. Leaves, e. Flowers, f. Branches.

Accepted Answer

Introduction / Context:Understanding tree structure helps in many reasoning problems. We move from underground support to trunk, to branching, to foliage, then to reproductive organs and products.Given Data / Assumptions:Roots are foundational.Trunk supports branches.Branches carry leaves and flowers; fruits arise post-flowering.Concept / Approach:Order by structural containment and typical developmental flow.Step-by-Step Solution:Roots (b) → Trunks (c) → Branches (f) → Leaves (d) → Flowers (e) → Fruits (a).Verification / Alternative check:Fruits develop from flowers borne on branches; leaves are vegetative organs preceding fruit.Why Other Options Are Wrong:They place fruits or flowers before supporting structures.Common Pitfalls:Treating “trunk” and “branch” interchangeably.Final Answer:b, c, f, d, e, a
