Question 1
Statements:
Some vertebrates are carnivores.
Some carnivores are domestic.
Conclusions:
I. Some vertebrates are domestic.
II. No vertebrates is a domestic.
Venn Diagram Method:
Step 1: "Some vertebrates are carnivores" → vertebrates and carnivores overlap partially
Step 2: "Some carnivores are domestic" → carnivores and domestic overlap partially
Step 3: Multiple possibilities exist:
- vertebrates and domestic may overlap (some A are C)
- vertebrates and domestic may be separate (no A is C)
- vertebrates and domestic may partially overlap
Analytical Method:
I + I combination gives NO definite conclusion.
The overlapping portions may or may not be the same part of carnivores.
Verification:
✗ Conclusion I: "Some vertebrates are domestic" - NOT DEFINITE (possible but not certain)
✗ Conclusion II: "No vertebrates is a domestic" - NOT DEFINITE (possible but not certain)
Answer: Neither conclusion I nor II follows
