Question

Choose the best word/ phrase to complete each sentence.
There’s no point _________ staying up all night if your exam is tomorrow.
a) On
b) With
c) Of
d) In

Answer 1

Hint: The blank in the statement has to be filled with a preposition; the preposition to be used here is the one which shows involvement in an activity.

Complete answer:
A preposition is a word that comes before a noun or a pronoun and establishes a relationship between the elements of a clause or words. Examples of prepositions are – in, of, at, into, etc.
The preposition given in the options can be understood.
Option (a) ‘On’ – indicates that something is already in position or something is on the surface instead of inside it.
Option (b) ‘With’ – is a preposition of time, it indicates the inclusion of something or the time at which something happens.
Option (c) ‘Of’ – is the most used preposition and is used to indicate possession of something by a person or to express the relation between a part of something to its whole.
Option (d) ‘In’ – this can be used to express involvement in an activity.
So, as the above sentence is talking about the activity ‘of not sleeping’ before the exam we can say that the most suitable solution would be option (d), i.e. the preposition ‘in’.
Therefore, the correct answer is an option (d).

Note:
In the above-given question, the option ‘of’ is totally irrelevant as it is usually used to show possession or relation between a whole and its part. Do not confuse it to show some activity.
