Ignore all my last questions about Russia I geuss since I’m not getting any responses I’ll just geuss and fail.

What do you need to know about Russia?

Explanation:

I'll try to help if you ask me specific questions.

the answer is       political office  

hope this .

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."
