Dear Dave,
I am having trouble understanding how did you see the assumption now vs. always? I correctly identified type, conclusion, type of flaw but the assumption - not.
Best,

There are two ways of identifying the error: by recognition (Ascriptive Error!), or by analysis: the President makes a claim about what is happening now (they're not leaving at that rate), based on evidence about all of history (if they'd always been leaving at that rate, they'd be gone by now).
And, as always, if you find that you cannot reach the answer by either of the above methods, use your correctness test!

hey MajorGeneral. I chose D, but struggled in r/o B. It seems to be a rate of change issue overall, No?

So, for (B) to be correct, we'd need the author to discuss a claim about rate of change (which she does!), then somehow confuse that with the size of the system. To do that, you'd probably need to have a comparison between two towns, and then say Town X is losing citizens at a much faster rate than Town Y, so Town X must be smaller than Town Y.
Here, the author didn't confuse the rate with the size; she said that the rate of change would affect the size.
Clearer?
