After a recent election, people who were not happy with the results began to change how they defined their public attitudes. They began to be more cohesive and think alike in order to enact change. Which theory would this follow?

Symbolic interactionism

Explanation:

Symbolic interactionism is a sociological theory that emerges as a result of practical situations/considerations, thereby allowing a person to think or behave in a certain way.

Symbolic interactionism is mostly important in the upbringing of a child as it helps the child to understand his social roles through his/her interaction with the environment.

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."
