The healing power of insight and self-awareness is least likely to be emphasized by therapists.
a. cognitive
b. psychoanalytic
c. behavior
d. humanistic

The answer is: C. Behavior

Behavioral therapists believe that both positive and negative behaviors are heavily influenced by the environment around us.

Rather than offering insight / self-awareness in order to treat psychological problems, they will put more focus on identifying which cause the negative behaviors within the patients' environment and remove it.

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."

okay what's the question?
