Answer:
the first one is more than likley the west nile virus, or the zika virus.
Since how, m<span>any African nations are multiethnic, after they kept their
colonial borders. The answer would have to be option B "</span>Wide ethnic diversity." Now multiethnic is <span>relating to or constituting several ethnic groups so it won't be option A. It also shouldn't be option D because Africans tend to use: </span>Algeria, Angola, and <span>Benin and these languages are from different country's. It would have to be option B because diversity is a</span><span> range of different things. Which means there are different religions, cultures, languages, and customs in Africa. Now finally it wont be option C because import is transporting goods inside the country and Africa is known by it's low resources so they rely on trade and exports to them.
Hope this helps!
