Have yall watched Megan is missing? bc it traumatized me... so if your thinking of watching it pleas please please don't. Its not scary scary, but that fact that its based on true events not to mention the last 25 minutes are scaring. So if your thinking of watching it just don't. ALOS DONT TALK AND MEET UP WITH PEOPLE YOU HVAE NEVER MET UNLESS YOU WANT TO END UP LIKE MEGAN AND AMY

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."
