S has 4 U and 3 A

F= 2 siblings

M= how many B?

1) F has to brothers

Since both of F's siblings are brothers, we now know that M has 5 siblings (2 B and 3 A)

Sufficient

2) M has 5 siblings

Insufficient. All we know is that there are 7 B/S altogether, which we knew from the prompt.


This looks exactly like a "C trap" to me. I'll go with A.
