What did africans mainly provide in the trade between east africa and asia?
a. grains and produce
b. raw materials
c. manufactured goods
d. art works

the answer is b just took the test

the fact that could also be added to column b is that during world war ii, specifically between the years 1941 and 1945, japan expanded its territory towards the indonesian territory in what was known later as part of the "pacific war". in that time, japan could conquer the philipines, singapore,   borneo, central java, malang, cebu, sumatra and various other islands of the area, therefore expanding its territory for a brief period of time.
