Which person is incorrectly matched with their field of work? a) margaret mitchell: author b) duke ellington: politician c) jesse owens: track athlete d) babe ruth: baseball player

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."
