Why was harry afraid of being sorted into the slytherin house?

Because of the bad reputation the house has gotten, with most deatheaters, otherwise known as Voldemort supporters, hailing from the Slytherin house. He mostly doesn't want to be apart of the house because of Draco Malfoy. Draco Malfoy seems stuck up and rude, and Harry doesn't want to end up like him.

Hope this helped!

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.
