2. What do we mean wher/ we say we can study communication from a quantitative/communication science perspective (hint: what does it mean we can
say about human comm behavior-definition of comm science would suffice here
also?) What is a theory? What are 2 traits of science that you would need to

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."

if you were a reader and you read the introduction, would you want to read more?

does it start with a question? if so, is it something you would want to read about?

and ask any friends or family for their opinion : )
