Question
The teacher asked us (1)/ if we have (2)/ completed the
assignment (3)/ before leaving the class. (4) The following sentence has been split into four segments. Identify the segment that contains a grammatical error and select the option which rectifies that error. If no error is present then mark option 5 i.e., 'no error' as your answer.Solution
The error is in part 2. The correct phrase should be "if we had" instead of "if we have." The past perfect tense ("had completed") is needed here because it refers to an action that should have been completed before another past action ("leaving the class"). Therefore, the sentence should read: "The teacher asked us if we had completed the assignment before leaving the class."
