Nubia provided each of the following items to the egyptians except

a. ivory

b. papyrus

c. animal skins

d. precious metals

B. Papyrus

Explanation:

Egypt and Nubia were bordering with each other, so naturally they traded between each other. The Nubians had their empire located in a position through which the trade between sub-Saharan Africa and North Africa was going on. Sub-Saharan Africa had lot of attractive goods to offer, the Nubians were able to acquire them, and since they were demanded by the Egyptians, they were selling those goods to them. Some of the things that the Nubians provided for the Egyptians were Ivory, ebony, animal skins, and exotic animals as pets, precious metals etc. The papyrus was not one of the things that the Nubians provided to the Egyptians though, as the Egyptians had it in abundance so they were cultivating it by themselves.
