The Framers feared that political parties would ___. * A. prevent people from voting
B. lead to too many impeachments
C. create divisions in the government
D. take over the job of congressional committees

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."

the correct answer is c.
