Question 9 of 25 Option A requires four years of higher education and $48,000, while option B
requires six years of higher education and $72,000. Option B requires
time and
money.

the money supply is the total amount of money available in the economy. how do changes in the money supply affect people and businesses?

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."
