Which of the following does NOT explain the significance of Charles Vill's new style
of cannon?
France will become richer than Italy because
they can sell this new cannon
France can destroy virtually any fortifications
built against them with a cannon
Italy's old structures can't hold anti-cannon
weapons

good question. i'll be looking into that. (this is a joke sir)

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."
