Incomplete question. I assumed you are referring to the article found on the History website entitled, "The Battle of Shiloh"

A. There were heavy casualties at the Battle of Shiloh.

Explanation:

We can make this conclusion because throughout the text there were several mentions about the losses on both sides (on the Confederate side and the Union army side).

For example, the first paragraph of the article explicitly stated,

"Both sides suffered heavy losses, with more than 23,000 total casualties, and the level of violence shocked North and South alike."

Also after mentioning the wins and losses experienced by the opposing sides during the Civil war, the article concluded, "It was a sobering reminder to all in the Union and the Confederacy that the war would be long and costly." This continuous reference to this forms the main idea of the articles.

D.

The test has already been written, and teachers have reviewed the questions thoroughly, so it is too late to make changes now.
