A response paper (D) is what you would write after you read an essay, analyze it, and write about some aspect of it.

A response paper is a good place to write about your personal viewpoint or what you learned by reading a book, an essay, or an article. It allows you to question the ideas and values that you read about. In other words, it's your chance to respond to what you have read.

halibut, flounder, tuna, and trout are all fish. so your first answer is 1.) fish. and since fish is edible, your next answer would be 3). edible

to describe those fishes more thoroughly, some of those fishes live in fresh water, and some of the fishes live in salt water, and that is not a thing that they all have in common. the question is asking what is common with all of the fish, so answer choices 2). fresh water and 4). salt water are not right.
