A“how-to” manual for installing a refrigerator is most likely to follow which organizational structore
cause/effect
chronological
problem/solution
process

Chronological,

It is most likely to be a chronological order, because there is a specific order you must follow when installing a fridge.

To be sure, let us use the process of elimination.

There surely isn't a cause nor effect in installing your fridge so thats out.

Chronological is arranging things in process of time. Let us say you are lacing your shoe. You wouldn't tie the shoe then put it on. Things have to happen in a specific order. Better known as chronological order, which so far seems like our most appropriate option. Now lets take Problem solution. Well theres no problem in installing your fridge so thats out.

Now this is tricky... process, now let us not be fooled here, process is doing things, but unlike chronological, it does not follow an order. So for all we know we could put our food in the fridge then install it.

SO we know have our answer to be chronological!

Hope I helped.

Sincerely,

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.
