Question

Fill in blank (68):

• A. Been
• B. Being
• C. Become
• D. To be

Answer 1

Answer: (A)

Been

A sentence is in active voice when the subject performs the action.

It is in passive voice when the subject receives the action.

The given sentence is in passive voice. The subject 'a change' cannot perform an action, but receive one.

Hence the verb form will be in passive voice.

Option A: 'Been' completes the verb phrase 'has been brought'. This phrase expresses the present perfect tense in passive voice. It agrees to the sentence: the action 'change' has just been completed.

Hence option A is correct.

Option B: 'Being' expresses a continuous tense. It forms a verb phrase with 'is' or 'are': is/are being brought about.

It does not form a phrase with 'has'. 'Has' expresses the perfect tense whereas 'being' expresses continuous tense.

Option C: 'Become' is a main verb and does not help the main verb in the sentence 'brought'.

When there's already a main verb, it requires other helping verbs like has, is, been, to form a tense.

Option D: 'To be' is the infinitive form and does not express any tense. It needs to be conjugated to express a tense.

Hence options B, C and D are incorrect.
