4. What was the name of the solution that led to Missouri becoming a state and what agreements were made in the solution?

Hey there! I'm happy to help!

The solution that led to Missouri becoming a state is conveniently known as the Missouri Compromise. Missouri would join the country as a slave state, but they agreed that no new slave states could be created above the Missouri Compromise line and that Maine had to be admitted as a free state to hold the balance between slave and free states.

I hope that this helps! Have a wonderful day! :D

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."
