Verified By Collegedunia
The Correct Option is A
Solution and Explanation
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.
"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.
