Kathy is most likely writing the discussion section. The discussion section is the part of the essay where you examine the significance of your findings and the importance of conducting the research. It is also the section in which you can explain your reasons for conducting the research, your future research ideas and the ways in which your research will connect to the existing literature. Therefore, this is usually considered the most important part of an essay.

would it be plagiarism to copy and paste off of here? ?

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."
