Mistake in REA for Hummanities?

[elizabethadavis]

I was just wondering if any one else has noticed the mistake in the Rea. I just took the third practice test. Question 30 asks which is the best book about WW1 and there answer is "For Whom the Bell Tolls"(which is about the spanish civil war) but it should be "A Farewell to arms". I know and caught this because I just took American literature. But I probally wouldn't catch something in art or artitecture. Does any one know if they're other mistakes as well? Thanks, Elizabeth
