All poets are sensitive. Some sensitive people are artists. Which conclusion is valid?
Correct: B
The middle term 'sensitive people' is distributed in the first premise (All P are S) but undistributed in the second premise (Some S are A). This is the fallacy of the undistributed middle. We cannot conclude that some poets are artists because the artists who are sensitive may not overlap with poets. The syllogism is invalid. None of the given conclusions follows necessarily.
