Gilberto had selected his topic and begun working on his specific speech purpose when he reread the assignment and realized that he was only going to have ten minutes to deliver his speech, not fifteen minutes as he had planned. What should he do?

answer: bvvvulhbjvuohu

explanation:

opoiokji

which sentences ? that question is incomplete

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."
