I submit to you that there is no answer to the quiz. It is not possible for a human to know whether Bank of America made money or lost money last quarter.
.. A bank’s earnings are a quantum event; they are entirely probabilistic, and the answer you get depends on who’s doing the observing. You make some guesses with some degree of statistical likelihood, and then you apply one of a half-dozen accounting regimes to the guesses, and you get a number, and then you’re like, ooh, look at this number, it’s so numeric.
