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