Question

Fill in the blank with a suitable option:
They refuse ________ out on trips if it's too hot.

• A. to going
• B. to go
• C. going
• D. go

Answer 1

The correct option is B to go

Answer : B

In the sentence, "they" is the Subject, "go" is the base form of the verb (as you can make out from the options) and "trips" is the object.

The structure of the sentence is that of Active Voice, i.e. Subject + Verb + Object. The subject is directly acting on the object.

And according to the grammar rules, the infinitive form of the verb is used in sentences with Active Voice.

The infinitive form can be made by adding "to" before the base form of the verb.

Here, the infinitive verb of "go", is "to go".

And thus, the correct complete sentence is:

They refuse TO GO out on trips if it's too hot.
