Read this excerpt from Fever 1793.
I hadn't heard about that. They were burying fever victims every day?
"How many have died, Mr. Carris?" I asked.
The first-person narration is meant to help readers understand that
Mattie trusts Mr. Carris.
Mattie is unaware of the extent of the problem.
Mr. Carris is responsible for burying the dead.
Mr. Carris reads the newspaper.

The correct answer is Mattie is unaware of the extent of the problem.

Explanation:

In this excerpt we can observe a conversation between Mattie and Mr. Carris.

As we can see, Mattie had no idea that they buried victims and neither did he know how many were the dead.

In fact, Mr Carris is the one who tells him that the almhouse is closed and that they want to protect residents from the disease, and that victims are removed from the flat once a day to burial.

With this information, we can say that the correct answer is: Mattie is unaware of the extent of the problem.
