Question

read general hooker’s description of the battle of antietam. what does this quote imply about the weapons used in this first “modern” war? the new weapons were not powerful. the new weapons were too difficult to use. the new weapons were extremely deadly. every stalk of corn in the northern and greater part of the field was cut as closely as could have been done with a knife, and the confederates slain lay in rows precisely as they had stood in their ranks a few moments before. —maj. gen. joseph hooker

Explanation:

The quote describes how the new weapons (in the first "modern" war, likely the Civil War) were extremely deadly, as the Confederates were slain precisely and quickly. The first option says the weapons were not powerful (incorrect), the second says they were too difficult to use (the quote doesn't imply difficulty in use), and the third says they were extremely deadly (matches the description of precise and quick slaying).

Answer:

The new weapons were extremely deadly.
