Question

_ _ _ _ _ _ you stop talking? Choose the most appropriate word to fill the blank.
A. Will
B. Must
C. Should
D. Could

Answer 1

Hint: The sentences that we read and study in grammar are made up of a few, specific elements that help in forming the basic meaning of the sentence. We have read and studied about the subject which is used to describe the nouns, pronouns, and noun phrases that occur before the verb in a sentence. It is the agent who causes the action.
Then in line is the object which can be a noun, a noun phrase, or a pronoun. It is affected by the action of the verb. Then the ‘verbs’ come into play and show what is being done in the sentence. They are accompanied by auxiliary or helping verbs like ‘can’, ‘will’, ‘shall’, ‘should’, ‘must’, etc.

Complete answer:
1. In order to find the word which will be the appropriate option to fill in the blank, we have to check each option one by one so that we can detect the correct option.
2. Option A, ‘will’ is incorrect because it denotes certainty of an event, which means the person is telling him to stop talking, which doesn't denote a request being made, so it is incorrect. Moreover, this sentence indicates that a request is being made. Hence, this option is incorrect.
3. The word, ‘must’ is used when there is a compulsion on the completion of a certain task which definitely is not the case here. Hence, this option is incorrect.
4. The word, ‘should’ is a bit lenient version of ‘must’. Both words imply that certain things should be completed or followed. But the latter is accompanied with a compulsion whereas the former is not that much strict. Thus, this option is also wrong.
5. The fourth option, ‘could’ is a conditional verb that expresses possibility and it makes a statement of ability. It is also used to make polite requests as in this case.

Hence the correct answer is option ‘(D)’

Note: Sentences are formed by a few grammatical elements that bring out their basic meaning. These elements can be the subject, object, verb and helping verbs. In this question, we studied about the words that accompany verbs and add more specified meaning to the action as well as to the sentence.
