An explorer whose last voyage ended in mutiny

Henry Hudson was an English sea explorer. The last known voyage of Hudson was in June 1611 when his ship was stuck in James Bay. A conflict arose where the crew members wanted to turn back while Hudson was opposing this. It is said that on 22nd June 1611 the crew mutinied and Hudson along with his son and some crew members were left in a small boat whose fate is still known to no one.

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."
