Rewrite the sentences correctly insert prepositions where required and remove the unnecessary one fi first this is the design I was looking.
plz help me my exam is there so I want to practice.

This is the design I was looking at.

Explanation:

Your question is a bit confusing because I'm not sure where the sentence I'm meant to rewrite starts from but I'll assume (I hope correctly) that the sentence is "this is the design I was looking"

In that case, when rewriting a sentence to include prepositions were required and removing the unnecessary ones, my best revision of the answer is in the "Answer" column.

A preposition is a word which precedes a noun or pronoun to show relationship between another word in the same sentence.

Some examples of preposition are: after, for, in, at, etc.
