The recession of 2007–2009 was: question 8 options: a) deeper than the recessions of 1990 and 2001. b) longer and more severe than the great depression. c) one of the shortest on record. d) dissimilar to the great depression in that the financial sector was not involved.

A) deeper than the recessions of 1990 and 2001.

Explanation:

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."
