Answer 2

Answer:

A student at an all boys high school should be on  his   best behavior.

Explanation:

Pronouns are the words that you replace with other nouns when your reader or listener already knows which nouns you mean. For example, you could say, "I have a dog. It's brown and white. It goes without saying that you describe your dog in the second sentence, since you already mentioned it in the first sentence. But following "I have a dog" with "brown and white" is grammatically incorrect.. . So with the pronoun “he is” you turn the phrase “brown and  white” into a full sentence: it is brown and white.
