I'm normally decent at games, but this question has me stumped. It's question 18 in section 3.

I'll post the rules and the question.

"A total of 6 boooks occupies 3 shelves -- one of the first shelf, two on the second, tree on the third. Two books are grammars -- Farsi + Hausa. Two are linguistics monographs -- phonology + semantics. Two are novels -- Vonnegut + Woolf. The rules are:

There is at least one novel on the shelf with Farsi grammar

The monographs are not on the same shelf.

The Vonnegut in not on the same shelf as either monograph."

#18:

If the Hausa grammar and the phonology monograph are on the same shelf, which must be true?

a) the phonology monograph is on the third shelf

b) Vonnegut is on second

c) semantics is on second

d) semantics is on first

e) woolf is on third

It seems to be that both d + e must be true. If H + P are on the third shelf, then F + V must be on the second. S can't be with "P" so it must be on first with W on third. If H + P are on second, F + V are on third. S can't be on second bc there's no room. S can't be on third bc it can't be with V. So it must be on first with W on second. Right? Can S ever be anyweher but the first shelf here? A W anywhere but the 3rd?

Any insight...please.
