Incomplete question. I inferred you meant knowing which word (s) in the sentence has a preposition.

Explanation:

Remember,  a preposition is a word or group of words used in a sentence to show time, place, or location/position. It is usually placed before a noun, pronoun, or noun phrase. For example, words like "in," "on," "of," and "to," "last," are commonly used.

The preposition in the sentence is underlined and bolded, where there is no preposition (#NA ) is written:

it should be repealed cuase its not fair

first question's answer is   a. they felt bad for the kitten, and started feeling guilty for not it.

second question's answer is c. she was trying to prevent the kitten from further screaming.

third question's answer is a. the mother and aunt fran faced their fears of cats, from it.
