Question

In the following sentence certain parts are underlined and marked P, Q, and R. One of the parts may contain certain error or may not be acceptable in standard written communication. Select the part containing an error. Choose D as your answer if there is no error. The student corrected all the errors (P) that the instructor marked (Q) on the answer book (R).

Correct answer (B) Q Solution Two past actions are described: the instructor marked the errors, and later the student corrected them. When one past action is completed before another, the earlier one takes the past perfect tense (had + past participle). So part Q should read "the instructor had marked". P, "all the errors", is correct. R, "answer book", is correct. Since Q contains an error, (D) "No Error" is wrong. Answer: (B) Q Turn this into a strength.
