Statements: No goats are bears. Some rabbits are bears. Which of the given conclusions follow?

1.Some rabbits are not goats

2.All rabbits are goats

3.Some goats are not rabbits

4.All goats are rabbits

AOnly 1 follows

BOnly 3 follows

CEither 1 or 2 follows

DEither 3 or 4, and 1, follow ✓ Correct

Correct answer: (D) Either 3 or 4, and 1, follow

Explanation

Conclusion 1 follows, and of 3 and 4 exactly one must, so either 3 or 4 follows.

'Some rabbits are bears' and 'no goats are bears' give 'some rabbits are not goats', which is 1.

For goats and rabbits the premises fix no definite link.

So neither 'some goats are not rabbits' nor 'all goats are rabbits' can be settled alone.

Being contradictories, those two form an either-or pair where one must hold.
