"man is the rational animal"?

animals have no logically wired brains, and can only think simple thoughts that are more instinct than anything. However, humans can think in words and have will power, logic, along with the basic instincts animals are born with. Some animals are considered smarter than others, and this is because they are born with more complex instincts.

Explanation:

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.
