Which following? dusjqkslsjss
Clothing in Africa is worn long and loose because it is too hot to wear tight clothing, but they still need coverage to protect themselves from bugs.
The one answer that I am missing among the options, but which is the correct one is: the geography of the region ( I assume that that's what was instead of the "7" in the first option).
It was very mountainous, with valleys and islands on which people lived -meaning there was a natural separation between the different settlements.
