Difficulty: Medium
Correct Answer: 3, 9, 4, 2, 10, 6, 8, 7, 5, 1
Explanation:
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:
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:
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
