If i have 1 car for price=13900$ and i have 7 cars how many money must be payed?

the actual answers are a, b, and d.

answer; i believe that the correct answer is (d); // supercontinent

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."
