A large piece of broken bottle was found at the scene of a crime. part of a broken bottle was found with a suspect. Can the top be uniquely associated (individualized) with the bottom? Explain.

yes it could

Explanation:

you could do DNA testing on the part that was found with the suspect

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."
