Here is a way that they can be verified very, very simply.
The Canadian dollar and the American dollar are at rough parity, fortunately for my analysis.
Census data shows that roughly 20% of the US population makes over 55K a year.
The population of the US is 311,591,917. 20% of that is 60 million, more or less.
60 million is, roughly 1% of the world's population.
That means that, for this to be true, no one outside of the US
would have an income over 55K. This is clearly untrue.
Thus, we can discard the quiz as false. There we go: verified.
The point here is quite simple: we can verify most claims using basic math.
