Statements:
1. Dogs do not bark on the arrival of friends of the family.
2. When A entered B's house, B's dog started barking.
Conclusion: A is B's enemy.
The conclusion drawn is:
Answer & explanation
Correct answer: option 3
The correct answer is Option (3) → Does not follow from the given statements.
A conclusion follows only if the statements leave no other possibility. Statement 1 says the dog stays quiet for friends of the family, so a dog that barks at A shows only that A is not a friend of the family.
A person who is not a friend need not be an enemy: A may be a stranger, a delivery person or a new visitor. The statements give nothing that makes A B’s enemy, so the conclusion does not follow.
