Covariation of cause and effect

Explanation:

According to my research on different causes of behavior, I can say that based on the information provided within the question the term that best exemplifies this is Covariation of cause and effect. This term refers to  the process of establishing that there is a cause and effect to relationship between the variables. In this situation the cause would be reading more newspapers, and the effect would be that the students display more knowledge of current events.

I hope this answered your question. If you have any more questions feel free to ask away at .

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."
