Question

Two statements followed by two conclusions are given. Taking the given statements to be true even if they seem to be at variance from commonly known facts, read all the conclusions and then decide which of the given conclusions logically follow from the statements. Statements: 1. Some animals are mammals.
2. All animals are not herbivorous.
Conclusions: I. Some animals are herbivorous.
II. All animals are mammals.

• A. only conclusion I follows
• B. only conclusion II follows
• C. neither conclusion I nor Conclusion II follow
• D. both conclusions I and II follow

Hint:

Remember: "Some" indicates a part of the whole, "All" indicates the entire set; be careful in interpreting negations like "All are not."

Answer 1

The Correct Option is A

Step 1: Understand Statement 1
"Some animals are mammals" means that a certain portion of animals belong to the mammal category, but it does not imply all animals are mammals.
Step 2: Understand Statement 2
"All animals are not herbivorous" means that not every animal is herbivorous; some animals may be herbivorous while others are not.
Step 3: Analyze Conclusion I
"Some animals are herbivorous" logically follows from Statement 2, because if all animals are not herbivorous, it means at least some animals are herbivorous.
Step 4: Analyze Conclusion II
"All animals are mammals" contradicts Statement 1, which says only some animals are mammals. Therefore, Conclusion II does not follow.
Step 5: Final decision
Only Conclusion I logically follows from the given statements.
