Susan recognized the face of someone she often sees at work. She smiled when she saw the person despite not knowing who the person was. This is an example of a. mere exposure effect. b. physical attractiveness c personal space d. proximity

answer; i believe the correct answer is (117);

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."
