Question

Fill in the blanks with the most suitable preposition:
We always review _______________ taking an exam.
a. Before
b. Since
c. With
d. To

Answer 1

Hint: Preposition are words placed before nouns to join/relate it to the remaining sentence or verb present in the sentence. Preposition comes with two words, ‘pre’ meaning before and ‘position’ meaning place.

Complete answer:
Option a: Before – Before is used to denote time in which an activity is done.
Example: I want your homework submitted before four o clock.

Option b: Since - It is used to state the time when the activity started itself without any precise time information.
Example: He has been living here since he was a child.

Option c: With – This is used to state the togetherness of the noun/pronoun with something or someone.
Example: He came to the party with his brother.

Option d: To – It is used to point out the noun toward an action or occurrence.
Example: He travelled to Kolkata.

Option ‘a’ is the most suitable preposition for the blank given in the sentence.
We always review before taking an exam.

Note: Here ‘before’ tells us that review which is an activity is done prior to the activity of taking the exam. Hence before is the most suitable preposition as it tells us the activity which is to be done before some other specific activity.
