Name some advantages and disadvantages of being assigned a matching spouse in the giver?

answer:

disadvantage: in the community, there is no love.   the most significant disadvantage of the family unit is that people do not experience either romantic or familial love.

the advantage of this arrangement is that there are no broken families.   there is no divorce, and no unwanted children.   everything is carefully arranged to ensure that the adults are compatible, and capable of providing a supportive environment for the children while they are with them.   since there is no love, there is also none of the pain associated with losing it.

answer; proximity;

the factors that the economies of the muslim empires prosper were:

1- land trade routes-located between three continents  

2- sea trade routes

trade contributed to the spread of muslim empires, and with that islamic culture led to a growing feeling of internationalism resulted in the transfer of technology, science, and other cultural forms.
