Question

Fill in the blank with most suitable option:
If you want to learn English, you ________ speak in your regional language during English lessons.
A) Should
B) Don’t have to
C) Must
D) shouldn’t

Answer 1

Hint: Verbs are the action words in a sentence that describe what the subject is doing. Along with nouns, verbs are the main part of a sentence or phrase, telling a story about what is taking place.

Complete step by step answer:
Option A) Should – is an incorrect answer because ‘should’ is used for expressing an opinion / advice / expectation / criticism about some past action or it can be used to ask for an advice. Thus, this is not applicable here in the sentence, hence, this is an incorrect answer.
Option B) Don’t have to – is an incorrect answer because ‘don’t have to’ is the negative form of 'have to'; it is used to remove necessity or external obligation. Thus, this is an incorrect answer.
Option C) Must – is an incorrect answer because ‘must’ is used to express a necessity (in the present or future); to make an assumption that something is true; to express an opinion about something that is logically very likely. Thus, this is an incorrect answer.
Option D) shouldn’t – is the correct answer because ‘shouldn’t’ is the contracted form of 'should not'; it is the negative form of the modal verb 'should'. Thus, this is the most appropriate answer.

Thus, the correct option is (D).

Note:
Here in the question, the speaker is expressing an advice that is not to speak in the regional language during English lessons but to try and speak in English so that they can learn better. Therefore, out of all the options, 'shouldn't' is the most suitable verb to complete the sentence, as it is used to express an advice in the negative form, that is an advice to not do something. "Should" is not suitable as it is used to express a positive advice that is to do something; if it is used here it would completely change the meaning of the sentence. Therefore it is not suitable. "Don’t have to" removes the necessity but does not express an advice and therefore it is also not suitable.
