All of the following are reasons why friendships are more highly valued by older people in late adulthood than family relationships expect?

There are no choices but the reason why we tend to value friends as we grow older is because these are bonds that we create on our own.  These are people who have been there for us throughout our lives. They are our link with the outside world since they are not our family members.  The longer we are friends with others, the deeper that bond becomes.
