Many standardized tests, such as the SAT, include questions that require the student to determine if a sentence contains a grammatical error — and if so, to choose the answer that does the best job of fixing that error. Part of a sentence is underlined. If there’s a problem with the underlined section, answers B, C, D, and E offer possible corrections. If there’s no error, the answer is A, which duplicates the underlined part without suggesting a change.
This set contains 32 such questions, along with an answer key and explanations.
