-
BOnly Conclusion II follows
-
CBoth Conclusions I and II follow
-
DNeither Conclusion I nor II follows
Answer
Correct Answer: Neither Conclusion I nor II follows
Explanation
Given data
- Some cows ∩ crows ≠ ∅.
- Some crows ∩ elephants ≠ ∅.
- Conclusions to test: (I) Some cows ∩ elephants ≠ ∅; (II) All crows ⊆ elephants.
Concept/Approach "Some–Some" premises do not force an overlap between the first and third sets; the overlapping parts of crows could be disjoint (different crows in each statement).
Step-by-step evaluation Conclusion I: It is only a possibility, not a necessity. There exist valid diagrams where cows and elephants do not overlap, so it does not follow. Conclusion II: "All crows are elephants" is far stronger than the premises and does not follow.
Final Answer Neither Conclusion I nor II follows
