Answer 3

The correct preposition in the sentence "He is not very good…. doing sums." is at. The answer is D) at.

A preposition is a word that relates a noun or a pronoun to some other word in a sentence. For example, in the sentence "She is sitting on the chair.", the preposition on relates the noun chair to the verb phrase is sitting.

Some prepositions can also be used as adverbs, such as on, in, up, down, etc. For example, in the sentence "He turned on the light.", the word on is not a preposition, but an adverb that modifies the verb turned.

The preposition at is used to indicate a point or place, such as "She is waiting at the bus stop." or "He works at a bank."

The preposition on is used to indicate a surface or position, such as "The book is on the table." or "She is on the phone."

The preposition in is used to indicate a location or enclosure, such as "He lives in New York." or "She put the money in her pocket."

The preposition with is used to indicate an accompaniment or association, such as "She is with her friends." or "He is angry with me."

The preposition upon is used to indicate a position above or on top of something, such as "The cat jumped upon the roof." or "He put his hand upon her shoulder."

The phrase doing sums means performing arithmetic calculations, such as addition, subtraction, multiplication, or division. It is a gerund phrase that acts as a noun in the sentence. For example, "Doing sums is fun." or "He is good at doing sums."

To indicate one's skill or ability in doing something, the preposition at is usually used, such as "She is good at singing." or "He is bad at driving."

Therefore, the correct preposition to use in the sentence "He is not very good…. doing sums." is at. The complete sentence is "He is not very good at doing sums."
