Difficulty: Medium
Correct Answer: Only (1) and (4)
Explanation:
Introduction / Context:
Syllogism questions test whether a conclusion must be true based strictly on the given statements. We cannot add outside facts, and we must avoid assuming overlaps unless they are logically compelled by the premises.
Given Data / Assumptions:
Concept / Approach:
Use classic set/venn reasoning. “All X are Y” means X is a subset of Y. “Some X are Y” indicates a definite non-empty intersection. Only conclusions that must hold for all diagrams consistent with the premises are valid.
Step-by-Step Solution:
Verification / Alternative check:
Draw Venn sets for Questions (Q), Answers (A), Writers (W), and Poets (P) with W entirely inside P. Place one element in A∩W (proves (1) and (4)). Place a separate element in Q∩A that is not in W. This diagram satisfies premises while falsifying (2) and (3).
Why Other Options Are Wrong:
Common Pitfalls:
Assuming that “some … are …” chains guarantee overlap across multiple “some” statements. They do not. Only a single “all” statement permits a definite subset relation.
Final Answer:
Only (1) and (4)
