Difficulty: Easy
Correct Answer: Neither Conclusion I nor II follows
Explanation:
Given data
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
