This is fast food nation by Eric Schlosser. I will put the essay from lesson 2 in the comments below. Ignore the part about you writing an essay.

"facing the rising sun of our new day begun

let us march on till victory is won.",

because the rising sun is a symbol of hope.

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.
