Difficulty: Easy
Correct Answer: if neither Conclusion I nor II follows
Explanation:
Introduction / Context:
The statement acknowledges the Sun as a source of light. It does not address other bodies or exclusivity. We test whether conclusions about the Moon or uniqueness of sources necessarily follow.
Given Data / Assumptions:
Concept / Approach:
From “A is a source,” we cannot infer “B is not a source,” nor “A is the only source.” Both conclusions import content not present in the premise.
Step-by-Step Solution:
1) I: The premise does not evaluate the Moon’s status; stating it is not a source is unjustified → does not follow.2) II: The premise does not claim uniqueness; other sources may exist → does not follow.
Verification / Alternative check:
Had the statement been “the Sun is the only source of light,” II would follow; it is not.
Why Other Options Are Wrong:
Admitting I or II moves beyond the text.
Common Pitfalls:
Illicitly converting a particular affirmative (“some A are B”) into a universal (“only A are B”).
Final Answer:
if neither Conclusion I nor II follows
