I said before that I was going through Lepore's Meaning and Argument. I was checking my answers for exercise 4.3 when I get to solution #27 and read:

Ambiguous. It is not the case that (John beats his wife because he loves her); because he loves her, it is not the case that John beats his wife.

To which I reply, "Whoaaaa." To be clear, problem #27 reads:

I don't think John will arrive until Tuesday.

which appears to be related to solution #28, and there are 30 problems and 31 solutions. Looks like they removed the problem but not the solution.

Tighten up, Lepore. (And Lepore's editor.)
