Quizzes: GMAT Sentence Corrections 1

Each of the following questions presents a sentence, all or part of which is underlined. Beneath the sentence you will find five ways of phrasing the underlined part.

Choose the answer that produces the most effective sentence; this answer should be clear and exact, without awkwardness, ambiguity, redundancy, or grammatical error.
