The factory that you worked in for 25 years burned down, and five of your co-workers died in the fire. What can you do to hold the owners responsible for breaking the law?

What Started The Triangle Shirtwaist Factory Fire? On March 25, a Saturday afternoon, there were 600 workers at the factory when a fire began in a rag bin. The manager attempted to use the fire hose to extinguish it, but was unsuccessful, as the hose was rotted and its valve was rusted shut.

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."
