C) The description of those who come to Johannesburg shows that people viewed Johannesburg as a solution to every problem, conveying the desperation of the people while foreshadowing the idea that Johannesburg will be overwhelmed by the number of people coming to it.
The excerpt repeatedly holds the word "Johannesburg", to put the focus on it as a place where anyone can go to, and where anything can be done, especially if it is aimed to solve a problem (To pay taxes, to secretly deliver an unborn child, etc.). It certainly conveys the message that Johannesburg is seen as a solution to every problem, and therefore it leads the reader with a feeling that in the future it may be largely populated by people who want to solve their issues.
I don't have time to do the whole essay here's an idea I guess:
I think that the United States should adopt a digital currency due to recent events of the pandemic and it would be more efficient. Cons could be that the system they use could get infiltrated but I doubt that could happen.
