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