Answer:
Intense social solidarity demands that some people be excluded. By asserting they were all related—that is, by excluding no one—Arembepeiros were actually weakening kinship's potential strength in creating and maintaining group solidarity.
Explanation:
Social solidarity is a sociological term, that is based on shared values and beliefs, which describes the interdependence relationship between individuals in a society, such that, individuals get to assume that they can improve the lives of other members in the group or society.
However, intense social solidarity demands that some people be excluded such that, the numbers of the members will not be too large to form the connections between them and will make the members to have the feeling of being among.
Hence, by asserting they were all related—that is, by excluding no one—Arembepeiros were actually weakening kinship's potential strength in creating and maintaining group solidarity.
