Question

School begins .......... Monday preposition

Answer 1

School begins on Monday.

The correct use of prepositions

• In the English Language, prepositions play a vital role for the completion of sentence structure.
• In the above sentence, the word "on" is used to connect two parts of the sentence. Without it, the sentence will make no sense.
• We can also use these words to show time, location, and direction.
• Some common examples of prepositions are to, from, upon, by, etc.

So the correct answer will be on.
