If you could choose one famous person (living or not) to be the substitute teacher
for a day, who would choose? What would
yoy hope to learn from them?

Morgan Freeman. I would love to learn about how he started being a actor and inspired me to not give up on life.

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."
