Which of the following revisions best corrects the shift in tone and maintains
a formal style throughout?

A. One of the main reasons the Great Depression began was that  after the stock market crashed and the banks started to fail,  people panicked and stopped spending money. When people stop  buying items, fewer items are produced and unemployment rises,  meaning even less consumption. This unfortunate spiral helped  plunge the nation into depression.

Explanation:

The above revision of the passage above maintains a formal style throughout. There is no fluctuation from informal to formal or vice versa. In the original passage, there was a switch from informal language to formal language. The use of the expression, "freaked out", is an informal language that should not be used in official and formal documents.

Also, the phrase, "buying less and less stuff" is also informal. The revision above maintains its formal tone throughout the text.

b because i dont see anything

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.
