Question

Complete the sentence-
We will not begin the work until they _______ to our conditions. (Agree)
a) Have agreed
b) Will agree
c) Will have agreed
d) None of the above

Answer 1

Hint: Read the given sentence carefully. Try to make out the core meaning of it. Find out the subject, predicate, and object of the given sentence.

Complete answer:
We have to fill in the given blank with the most suitable form of the verb ‘agree'. There are different tense forms given in the options, we have to choose the best one of all. The sentence conveys that some people will not begin the work until and unless the other people accept their conditions.
Now, let us examine all the given options to find out the correct answer-
Option ‘a’ is Have agreed. ‘Have' is a verb which means to possess, hold, or own something. It cannot be the correct answer as we cannot use ‘have’ with ‘will’ in a sentence.
Option ‘b’ is Will agree. It cannot be the correct answer as the blank wouldn’t be filled with a future tense of any verb.
Option ‘c’ is Will have agreed. It cannot be the correct answer as well because it is in the future perfect tense, which is not required here.
Option ‘d’ is None of the above. It has to be chosen if all the other three options are incorrect or not suitable for the given sentence. It is the correct option, as no other option is suitable for the blank. Hence, option ‘d’ is the correct option.

Note:
This sentence will have the present simple tense of the verb ‘agree', which is ‘agree’ itself. It is not present in the given options.
