The correct answer is - politics.

The cities of the likes of Geneva, Brussels, and Washington, are all cities that have global political influence, thus they are considered as global cities, even though when compared with the other big influential cities they are only a drop in the glass.

The political influence is the main asset of this cities, so that is why they have their power. Geneva is a city where big portion of the global politics are decided and discussed by the big powers. Brussels is the city in which the EU politics are decided, thus it has influence on pretty much all oft he continent, but also in the world. Washington is the capital of the USA, still the most powerful country in the world in pretty much every aspect, so what is decided there, has global impact for sure.

since there isn't any suggested answers i will give you the reason and hopefully you can figure it

south africa, or rather all of africa, has not been in the location in which it is nowadays throughout the geological past. after the super-continent pangaea started to break apart, gondwanaland, in which was africa, moved further south, and parts of it came to be very close to the south pole. because the climate in this part of the world is very cold due to the very dispersed sun rays in there, what is now south africa, started to freeze, and the conditions were right for the formation of glaciers. the glaciers existed up until the period when gondwanaland started to break apart and what is now africa started to move towards north, sp it warmed up and the glaciers melted.
