Africa, a continent.

 

I've checked your work and all of you have written or implied that Africa is a country. Africa is a continent, not a country. There are a lot of countries in Africa. 

Some countries in Africa are extremely rich so it is wrong to write that Africa is poor. Only some countries in Africa are in poverty, not all of them. If you write Africa is poor or people in Africa are poor, you are saying all of the people in Africa are poor. Please remember that.
