A) play
B) coalition formation
C) dominance hierarchies
D) food-sharing
E) grooming

Accepted Answer

Grooming has been observed as a central activity for reinforcing social relationships in many primate species, including chimpanzees, bonobos, and macaques. It has been observed to reduce tension and stress, create a sense of social bonding, and improve cooperation within groups. While play, coalition formation, dominance hierarchies, and food-sharing may also contribute to social relationships in primates, grooming appears to be the most significant factor.
