Syllogism: Evaluate which conclusions logically follow from the given statements (possibility vs. necessity). Statements: Some cows are crows. Some crows are elephants. Conclusions: I. Some cows are elephants. II. All crows are elephants. Choose the correct option about which conclusion(s) follow.

Difficulty: Easy

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
