Difficulty: Easy
Correct Answer: Only assumption II is implicit

Given Data / Assumptions:
Concept / Approach:
Step-by-Step Solution:
Assumption II is necessary: without sensory experience of taste, the proposed contribution to intake is impossible.Assumption I is not necessary: taste can still influence quantity or frequency of eating even when survival or nutrition is the main motivation.Verification / Alternative check:
Drop II: The mechanism collapses. Drop I: The statement remains valid; taste may be a secondary but real contributor.Why Other Options Are Wrong:
I / Either / Neither / Both either overstate the role of pleasure or ignore the sensory precondition.Common Pitfalls:
Equating “contributes” with “is the sole or primary reason.”Final Answer:
Only assumption II is implicit
