Occam's razor

I often find an awkward sentence in a workbook or reference books for university entrance examinations in Japan. I'm saying it's just "awkward," not "wrong." See the sentence below:

1) What made him get angry with her?

It is grammatically correct, but you can cross out the word "get" to simplify the sentence.

2) What made him angry with her?

Why didn't the author choose Sentence 2) over Sentence 1)? Just because they wanted to teach the usage of a verb: "make + object + the base form of a verb"

By the way, why is 2) better than 1? Probably, most grammarian in Japan can't answer such a simple question: Native speakers of English prefer a simple form to a difficult one.
