Question

Fill in the blank with the most appropriate word:
 I wonder where Sue is. She promised not to ____ late.
A.got
B.happen
C.be
D. Go

Answer 1

Hint:The sentence is in present tense ,so the option should be chosen which is generally used with present tense more appropriately according to the question.
The sentence is about the concern for the person addressed. So, the option should relate to the word late.

Complete answer:
Option A-got- is not the correct answer because it is grammatically incorrect. Here, the option is in the past tense while the sentence needs an answer to be in present tense. So,this option is inappropriate and wrong.

Option B-happen- is an incorrect option because this option is totally inappropriate to be related to late. This option is not valid with the sentence and hence, grammatically wrong.

Option C- be- is the correct answer. This option is in present tense and generally used to address a sentence having opinion or impose order or request something or someone.

Option D- go- is an incorrect option because it is grammatically wrong. Go can also be a correct option here, but “She promised not to go late" indicates that the 2nd person is asking the 2st person not to reach late somewhere which sounds wrong as it seems the person is asking for Sue (2nd person) who is late. So,” she promised not to be late" is correct.

Hence the correct answer is option ‘C’.

Note:When sentences are in present tense, be is preferably used rather than any other infinitive.
The person is concerned about Sue being late, be goes perfect as the answer to the sentence.
Be is used as present tense while been is used as past participle and being as present participle.
Although, more than one option seems to be correct, we have to always choose the answer which is grammatically more appropriate and suitable.
