Choose the meaningful life-stage order for a human being: (i) Infant, (ii) Old, (iii) Adult, (iv) Adolescent, (v) Child. Arrange from earliest to latest stage in everyday human development.

Introduction / Context:
This item checks your understanding of the natural sequence of human development. From earliest infancy through old age, we traverse recognizable phases. Logical sequence questions require mapping these phases to a coherent timeline and eliminating any order that contradicts universal growth patterns.

Given Data / Assumptions:

• Stages: Infant (i), Child (v), Adolescent (iv), Adult (iii), Old (ii).
• We use a standard social/biological progression.

Concept / Approach:
Life-stage order is widely accepted: infant → child → adolescent → adult → old. The transitions reflect physical, cognitive, and social milestones (e.g., puberty into adolescence, legal/biological maturity into adulthood). Any alternative that displaces these in a non-sensical way is rejected.

Step-by-Step Solution:
Step 1: Start at infancy: (i) Infant.Step 2: Next is (v) Child.Step 3: Adolescence (iv) follows childhood.Step 4: Adulthood (iii) follows adolescence.Step 5: Old age (ii) concludes the sequence.Therefore, (i), (v), (iv), (iii), (ii) is correct.

Verification / Alternative check:
Check against legal/educational markers: schooling aligns with childhood/adolescence; workforce independence aligns with adulthood; retirement and advanced age align with old age. The selected order is coherent with these societal anchors.

Why Other Options Are Wrong:

• Any sequence starting with adult or old contradicts human development.
• Placing adolescent before child ignores puberty as a post-childhood transition.
• Swapping adult and old defies the linear aging process.

Common Pitfalls:
Confusing the labels “child” and “adolescent,” or reading left-to-right without assessing biological plausibility.

Final Answer:
(i), (v), (iv), (iii), (ii)
