All fathers are males. No male is a female. What conclusion follows about fathers and females?
Correct: C
From 'All F are M' and 'No M are Fm' (where Fm = female), we can chain the relationship. All fathers are males, and no male is a female, so no father can be a female. Therefore, 'No father is a female' follows validly. This is an E conclusion derived from an A and an E premise (AEE-1), which is a valid mood in the first figure.
