Members' motivation in the group is not usually affected by

A) Whether members have a friend in the group
B) What can be accomplished through the work of the group
C) The processes that occur in the group
D) The worker's role in the group

Having a friend in the group does not usually affect a member's motivation in relation to the group's goals, tasks, or outcomes. Motivation is more directly influenced by factors such as the group's objectives (B), the processes within the group (C), and the individual's role within the group (D), which directly relate to the group's functioning and the individual's engagement with the group's tasks.
