With Respect to Children's Friendships

With respect to children's friendships:

B) hostility between childhood friends predicts hostile romantic relationships in young adulthood, but this effect disappears when parent-child hostility is controlled.
C) without shared imaginative play, children are unlikely to develop empathy.
