Syllogism — Books, novels, poems (do not force overlap): Statements: 1. All books are novels. 2. Some novels are poems. Conclusions: I. Some books are poems. II. Some poems are novels.

Difficulty: Medium

Correct Answer: Only Conclusion II follows

Explanation:


Introduction / Context:
The trap here is to assume that because Books lie inside Novels and “Some Novels are Poems,” the Book subset must meet the Poems subset. That is not forced by the premises.


Given Data / Assumptions:

  • Book ⊆ Novel.
  • ∃ (Novel ∩ Poem).


Concept / Approach:
Conclusion II is a direct restatement of statement 2 (intersection is non-empty). Conclusion I would require that the novel-poems include at least one Book; nothing guarantees that. The novels that are poems could be those outside the Book subset.


Verification:
Venn: draw Novel as a big set containing Book as a proper subset. Place the Poem overlap entirely outside Book; the premises remain true while I fails.


Final Answer:
Only Conclusion II follows.
