Describe how islam began and discuss the similarities and differences between islam, judaism, and christianity.

All these religions believe in one God. Islam and Christianity are similar because they've got important prophets like Jesus and Muhammad. Judaism shares some related beliefs with Christianity like praising one God, the only thing different is that they do not believe that Jesus is the son of God. Christians believe that Jesus is the way to heaven, other religions, like Islam, believe that you have to live a life with out sin. Christianity says that everyone is a sinner, while Islam believes that by following rituals, they are clean from sin.

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."
