Conversation Two
W: Hey, Tom! I heard that you are auditing at the history class. How do you like it?
M: Pretty good! Prof. Lincoln talked a lot about Africa yesterday. [23]Do you know which African country has the strongest economy?
W: [23]I would guess South Africa. It's probably got the most modern infrastructure of all the African countries.
M: [23]Exactly! And Prof. Lincoln said that it is one of the most stable democracies in that part of the world.
W: Sounds interesting. What else did Prof. Lincoln say?
M: As developed as it is now, that's not to say that there haven't been problems. I bet you can guess what I'm referring to.
W: Apartheid?
M: Yes, under apartheid, the government maintained a policy of separating the white minority and the black majority. [24]Early on, black people were barred from being members of parliament. It was a whites-only government.
W: Does everyone speak English in South Africa?
M: No, not necessarily. Most people do, but there are actually eleven official languages. English is one. The most commonly spoken language that's native to the area would be Zulu.
W: And... and how about the population there?
M: Interestingly, South Africa has the largest population of people of European descent in Africa, and the largest Indian population outside of Asia. Not only that, [25]it also has the largest mixed race community in Africa.
W: Oh, you really know a lot about that country now! I guess I want to audit at the history class next semester.
M: I bet you won't regret it.
