Why should you be aware of an interviewer’s “hidden agenda”? so you can find ways to address them in your answers so you don’t fall into the interviewer’s trap with the agenda so you don’t offend the interviewer by not knowing the agenda so you arrive at the right time during the hidden agenda

there are number of topics. you can pick any one of these topics:

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.
