The battle at Fort Sumter is symbolic because it . A. saw the first shots of the U. S. Civil War
B. was a huge turning point in the war for the Confederates
C. was the bloodiest single day of battle
D. gave the Union control over the Mississippi River

A. saw the first shots of the U.S. Civil War

Explanation:

When an unarmed resupply mission to the fort was shot down by Confederate forces, it triggered the war.

d. i assume the underlined word is "role." reformat if it isn't.

explanation:

role is closest to part because when replacing words, "playing a vital decision," "playing a vital activity," and "playing a vital dollar" don't make logical sense. the only meaningful choice is "playing a vital part."

this fits one of merriam-webster's definitions of role: "a function or part performed especially in a particular operation or process."

well, i can't read it so i'll ask you questions about it : )

does it start with a question? if so, is it something you would want to read about?

and ask any friends or family for their opinion : )
