not sure i can make sense of it either, but here goes...
The answer is A but I'm unsure how and why LOL
i don't get how it could be A. wouldn't that be faulty distribution?
to me it looks like you can say that
1. all ZIFS are SIFS,
but
2. only some SIFS are RIFS,
therefore
3. some SIFS are not RIFS,
and consequently
4. some ZIFS are not RIFS
B could be correct,
1. all HIFS are PIFS
and
2. all PIFS are ZIFS,
therefore
3. some HIFS have to be ZIFS
but not C, because
if you substitute SIFS for men and RIFS for hairy people, you have
1. some men are hairy people,
but it doesn't follow that
2. all hairy people are men.
D same thing as C.
E could be correct too because
1. all PIFS are ZIFS
means that
2. some ZIFS are PIFS
as in "all stars are hot things,
means that
some hot things are stars.
