Question 1
Statements:
No fish is a wild.
All wild are warm-blooded.
Conclusions:
I. No fish is a warm-blooded.
II. Some warm-blooded are not fish.
Venn Diagram Method:
Step 1: "No fish is a wild" → Circles of fish and wild don't overlap
Step 2: "All wild are warm-blooded" → Circle of wild completely inside warm-blooded
Step 3: fish is separate from wild, but warm-blooded may overlap with fish
Analytical Method (E + A = O*):
No fish is a wild (E) + All wild are warm-blooded (A) = Some warm-blooded are not fish (O*)
Verification:
✗ Conclusion I: "No fish is a warm-blooded" - DOES NOT FOLLOW (warm-blooded circle is larger and can overlap with fish)
✓ Conclusion II: "Some warm-blooded are not fish" - FOLLOWS (the part of warm-blooded containing wild doesn't contain fish)
Answer: Only conclusion II follows
