Saftey from the ground up is a movement that gets managers out on the shop floor assessing the safety of employees?

False

Explanation:

This is not true as safety from the ground up doesn't not necessarily have to be a movement that will now get managers out on the floor to assess the safety of all employees.

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."
