1. What is each person’s role in the group? What do they do? What do other people expect from them? 2. Who in your opinion contributes most to the group's work? 3.

Explanation:

NOTE : Your question is not completely and well stated, but i will explain to you what group role is and the importance of communication in the group. I believe this will answer any question that you have in mind.

The group role is the role and responsibility of a leader and the individual members working within the group. It refers to the function that individual members of a group will perform within the group as a whole.

    racial conflict and discrimination has existed ever since man learned to kill with rocks and bones. these conflicts arose from disputes between territory, power, wealth, religion, or simple difference. some of the most infamous racial disputes include slavery, the holocaust, and the civil rights movement.

    these listed disputes often resulted in casualties from all sides. riots, wars, imprisonment, and lynching are all commonly associated with racial conflict on severe levels.

      however, racism is an improving issue in recent decades. people are being more accepting and welcoming of diverse populations. though, the world isn't perfect and it will take much more time, if ever, until the world is rid of racism.
