Writing>Identifying Sentence Errors

The following sentence contains either a single error or no error at all. If the sentence contains an error, select the one underlined part that must be changed to make the sentence correct.If the sentence contains no error, select choice E.

The results of the study indicate that the new drug is both safer and more effective than was previously assumed. No error

(A) indicate
(B) both safer and
(C) was
(D) assumed
(E) No error

答案和解析

答案:E

解析:

There is no error in this sentence. The plural present tense verb "indicate" agrees with the plural subject "the results." The phrase "both safer and" appropriately introduces the compound subject complement "both safer and more effective." And the verb phrase "was … assumed" appropriately indicates an action that occurred in the past: i.e. what scientists thought before the new studies.
