Question 1
Statements:
Some invertebrates are mammals.
All mammals are wild.
No wild is a vertebrates.
All vertebrates are carnivores.
Conclusions:
I. Some invertebrates are wild.
II. No mammals is a vertebrates.
III. Some carnivores are not wild.
Complex Multi-Statement Analysis:
Statement Chain:
1. Some invertebrates are mammals → Partial overlap
2. All mammals are wild → mammals inside wild
3. No wild is a vertebrates → wild and vertebrates separate
4. All vertebrates are carnivores → vertebrates inside carnivores
Checking Each Conclusion:
✓ Conclusion I: "Some invertebrates are wild"
Some A are B (I) + All B are C (A) = I + A = I - FOLLOWS
✓ Conclusion II: "No mammals is a vertebrates"
All B are C (A) + No C is D (E) = A + E = E - FOLLOWS
✓ Conclusion III: "Some carnivores are not wild"
All D are E (A) + No C is D (E, converted) = A + E = O* - FOLLOWS
Answer: All conclusions I, II and III follow
