1. Why did the people of Greek participate in sports?

It was a test of strength for the people.

Explanation:

Back in Greek times, people competed in the Olympics. That's where it all started. They would do games in honor of their gods. The main ones they celebrated were:

Nike, goddess of victory

Zeus, lord of the sky

Apollo, god of the sun and music

Hermes, god of thieves.

answer; reactive is your answer; good luck

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."
