Answer 2

Answer:

I saw a helicopter flying above a lake.

Explanation:

The term above means: higher than the level and is best-described preposition used in this sentence. Prepositions are words that are 'preceding a noun or a pronoun' and expressing a relationship to the other element which was present in the clause.

Prepositions are therefore words which are required to describe the location, time or place in a sentence or a phrase. Without prepositions, the sentence does not seem to make any sense and therefore their requirement in the English grammar is important.
