From the words or group of words lettered A to D, choose the word or group of words that best completes each of the following sentences.

Mary shouldn't have disobeyed the teacher,_________?

Answer Details

The best word to complete the sentence is "should she." The sentence is in the negative form, stating that Mary should not have disobeyed the teacher. When using negative sentences, we usually use tag questions to confirm or emphasize the negative statement. Tag questions are short questions added to the end of a sentence. The tag question for negative sentences is usually the opposite of the statement, so we use positive tag questions for negative statements. Therefore, the correct tag question for this sentence would be "should she," making the complete sentence "Mary shouldn't have disobeyed the teacher, should she?" The other options do not fit the context of the sentence, making "should she" the correct answer.
