When genghis khan married his wife borte, his in-laws gave him a beautiful sable coat as a wedding present. why would genghis khan immediately give the coat away to the leader of a neighboring tribe?

he needed to form alliances with other tribes in order to his family survive.

he owed money to the other tribe's leader, and the coat was valuable to enough to pay his debt.

he had no use for a coat of this type, given mongolia's mild climate.

he did not want his wife to have the coat and he feared she might try to claim it.

-He needed to form alliances with other tribes in order to help his family survive.

Explanation:

GIven the fact that at that time in his life, his family was living a very precarious and meagre life,  the sable coat served as a simbolic gesture when he surrendered it to a neighbouring leader. By this gesture, Genghis Khan recognized him as an adoptive father, integrating him and his family into the tribe. The leader had been an old ally of Gengis' boiological father, and the gesture ensured that his family would have protection against other hostile tribes of the steppe, as they were taken in as members of their tribe.

warfare was the primary means of cultural transmission in both regions.

according to my calculation, the answer is d.
