My main activity this summer has been LSAT review. So I thought I'd post a logic game (from a previous LSAT) for all the critical-reasoning masochists out there. For an accurate test simulation you should try to answer all the questions (excluding the extra credit question) in 8 minutes or less. Welcome to my twisted world; I'll post the answers in week or so.
Questions 6-12
A total of six books occupies three small shelves - one on the first shelf, two on the second shelf, and three on the third shelf. Two of the books are grammars - one of Farsi, the other of Hausa. Two others are linguistics monographs - one on phonology, the other on semantics. The remaining two books are novels - one by Vonnegut, the other by Woolf. The books' arrangement is consistent with the following:
There is at least one novel on the same shelf as the Farsi grammar.
The monographs are not both on the same shelf.
The Vonnegut novel is not on the same shelf as either monograph.

(A) first shelf: Hausa grammar
second shelf: semantics monograph, Vonnegut novel
third shelf: Farsi grammar, phonology monograph, Woolf novel

Solved it already? Put this in your pipe and smoke it for extra credit:

My brain hurts!
What does it say about me that I found the second puzzle exponentially easier than the first? (Of course we'll see the truth when the answers arrive . . . )
Most of Evans friends are young and smart. Most young and smart people read and understand blogs. I read this blog. Hmmmm this is not going well for me.
Man, I'm struggling.
Took me about 12 minutes and it was a brain-burner! I'd post my answers, but I'm not sure you want spoilers in here. I'll be checking back soon for the results!
I think they were trying to throw you with assigning phony labels to the books - look past the labels and stay out of trouble
