Quizplus · Accepted Answer

The research showing that group cohesion increases when resources or survival depend on group membership suggests that humans have a strong need to belong to a group for survival, which supports the idea that humans have a strong need to belong (option B). This idea is supported by numerous studies in social psychology, which have shown that people's need to belong is a fundamental human motive that shapes their thoughts, emotions, and behavior. Sexual selection (option A) refers to the evolution of traits that increase an individual's mating success, whereas survival selection (option C) refers to the evolution of traits that increase an individual's chances of survival and reproduction. Although group cohesion may be important for survival, it does not necessarily involve sexual selection. Option D (that humans have evolved universal emotions) is not directly supported by the given information about group cohesion and resources.
