Why was the mayflower compact important? it was the first document in which american colonists claimed a right to govern themselves. it gave the plymouth colonists a legal standing for their faith in english courts. it was the first document written in english that gave the right to vote to women as well as men. it was the first time a group was elected to make rules and laws in north america.

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."
