Which of the following techniques have actors of color used to assimilate into the dominant culture?
A. Passing for white
B. Playing stereotypical roles
C. Changing their names
D. All of the above

most cajuns resided in acadiana, where their descendants are still predominant

c. reserves power to the states and people

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."
