Introduction / Context:
The statement links a sensory attribute (taste) to nutritional intake and, ultimately, survival. It implies a mechanism: palatable taste encourages sufficient intake.
Given Data / Assumptions:
- Claim: Taste contributes to nourishment intake.
- Assumption I: People eat for the enjoyment of taste.
- Assumption II: People are capable of perceiving taste (taste sensation occurs).
Concept / Approach:
- To claim taste contributes to intake, it must be perceived by eaters; otherwise taste could not influence behavior.
- However, saying taste contributes does not require that enjoyment is the primary reason for eating; survival, culture, or habit may be primary motives.
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
