Aiden is on the debate team. When he arrives at practice, he is handed a piece of paper with a topic written on it, and allowed two minutes to come up with a speech. Aiden is being asked to deliver a(n) speech.

Impromptu.

Explanation:

As per the question, Aiden is asked to deliver an 'impromptu' speech as he got very little time i.e. two minutes for the preparation of the speech. 'Impromptu' speech is described as the speech that is delivered without any kind of preparation. Such speeches are delivered with little or no preparation time and requires advanced knowledge about the subject and follows a defined structure and clear ideas. Thus, 'impromptu' speech is the correct answer.

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.
