Final answer:
Individuals with open-minded perspectives are most likely to have cross-ethnic friendships due to their willingness to engage with diverse viewpoints and backgrounds, unlike those with cultural biases, limited exposure to diversity, or exclusive social circles.
Step-by-step explanation:
Considering homophily and its limitation on exposure to diversity, the individual most likely to have cross-ethnic friendships would be someone with open-minded perspectives. This contrasts with individuals who have strong cultural biases, limited exposure to diverse communities, or exclusive social circles, as these factors contribute to homogeneity within a social group and limit the different viewpoints one is exposed to. Therefore, those with open-minded perspectives are more inclined to form relationships with people from various ethnic backgrounds, contributing to a more diverse social experience.
