Question

Fill in the blank with the most appropriate word-
A retired person ______ go to work.
a) Doesn’t have to
b) Has to
c) Have to
d) Don’t have to

Answer 1

Hint: Read the given phrase/sentence carefully. Try to make out the meaning of it and find the subject or the predicate or the main object of the sentence.

Complete answer:
The given sentence conveys that any retired person is not in need of going to work. We have to fill in the blank with the correct form of the verb.
Now let us examine all the options to find out the correct option -
Option ‘a' is Doesn’t have to. It is the correct option because it is used when speaking in the third person singular.
Option ‘b' is Has to. It cannot be the correct option because it suggests a requirement, meaning that absolutely no other option is acceptable.
Option ‘c' is Have to. It cannot be the correct option because it is used for saying that somebody must do something or that something must happen.
Option ‘d' is Don’t have to. It cannot be the correct option because it is used when speaking in the first and second person plural and singular and the third person plural, e. g. (“I,” “you,” “we,” “they”).
As we have analyzed all the given options, we can easily figure out the correct option. Here, the correct word to be filled in is - doesn't have to. Hence, option 'a' is the correct option.

Note:
All the other options are plausible distractions. You must know the usage of 'have' and 'has'. 'Has' is used for singular forms, and 'have' is used for plural.
