Final answer:
People combat prejudice by promoting collaboration, inclusive education, and taking action against discriminatory behavior.
Step-by-step explanation:
People have tried to combat prejudice in various ways. One way is by promoting collaboration and working towards common goals. For example, the Robbers Cave experiment showed that when two opposing groups at a camp worked together, prejudicial attitudes decreased. Another approach is through inclusive education, such as the jigsaw classroom technique, where students from different backgrounds work together on assignments. Additionally, individuals can take action against prejudice by speaking up and challenging discriminatory behavior, as exemplified by the pleasant woman in the story who intervened when the store employee ignored a customer of color.
