The Robbers Cave Experiment showed that an effective way to reduce prejudice and tension between members of different groups was to:
A. create a situation in which members of different groups cooperate to achieve a common goal.
B. set up competitive situations in which members of different groups can demonstrate their expertise.
C. provide opportunities for members of different groups to socialize.
D. force members of different groups to have contact with one another in a stressful situation, in this case being trapped in a cave.
