African immigrants are mainly () A from Europe and Asia, B from America and Europe, C from Arabs and D from blacks.

Among the immigrants from Africa, the mainland (Europe) is the largest, mainly because (Africa was once a colony of several European countries), and there are more people from the Middle East, because (North Africa and the Middle East belong to Muslim countries).

I hope there is no word limit.

Is this ok?
