961,121

Explanation:

According to the 2010 National Census, there are 961,121 immigrants registered with the government as living in Mexico, the majority of whom are US citizens. This is almost double the 492,617 foreign-born residents counted in the 2000 Census.

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."
