The First Amendment rights to freedom of speech and press are important because they - A. allow people to criticize the government without fear of being punished
B. prevent special interest groups from having influence on political elections
c. help to ensure that the news and other media remain free of bias
D. allow people to exercise their democratic rights on Election Day

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."
