Although all six state governments faced budget problems after the economic downturn of 2007, the problems were
worse in California because much of it revenue came from a large number of high-tech industries.
(A) worse
(B) worst
(C) more
(D) great
(E) worsening
OFFICIAL EXPLANATION:
B. This example has only one underlined word, which is nice because you know just what to focus on. If you simply go by what sounds right, you may think this example is fine the way it is. You probably hear English speakers use worse like this in everyday conversations. But the GMAT doesn’t test common spoken English; it tests standard written English.
You use worse to compare two entities and worst to compare three or more.
The sentence talks about a situation among several state governments. Worse would be appropriate for a comparison between two states. But this sentence compares budget problems in six states, so instead use the superlative form worst to single out poor California. That’s the answer you find in Choice (B).
You can double-check your answer by reading through the other choices. You’ve found an error, so Choice (A) can’t be right. Choices (C) and (D) aren’t superlatives, and Choice (E) uses the progressive form were worsening, which changes the meaning of the sentence.
