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:

he gives his freedom of speach

explanation:

(i can't select because there is no options but, i will answer) using evidence effectively. most of the assignments you will do in university will ask you to make an argument, to take a stance, or to prove a hypothesis. the best way to do this is to research the topic, develop a thesis statement, hypothesis, or claim and then use evidence to support this claim.
