Bad wording or trick question (spoiler?)

One of the questions from Hunch is:
A generous friend offers you one of two envelopes. Which one do you choose?
Envelope A: Definitely contains a $1,000 bill
Envelope B: Has a 75% chance of containing $250, and a 25% chance of containing $2,500
Mathematically, A is the better choice BUT there are no $1000 bills in circulation so it would have to be a counterfeit, making B the better choice.
Was the "$1000 bill" wording intentional or did Hunch just mean "$1000"?

Yeah, we probably didn't mean to have bill in the question when we wrote it.
But, the question now becomes how much the loss of that one word would change the question and all the training we have already. It eliminates the very quandary colin is highlighting, which may have been the focus for many people when answering this question.
I guess my comment was expressing my support for keeping the question about this very quandary.

Good catch colinfoster. I personally always interpreted this question as a gauge of how risky you are. It's not perfect in that matter since the expected value of option B is $812.50 and not $1,000... but then again I've seen people do crazier things on Deal or No Deal.

Hmmm... I know I'm a bit new around here (minutes old, really) but if the Hunch engine is matching the similar opinions of people then this question should be mucking up the works.
It would be matching those that picked B because they are (bad) gamblers with those that picked B because they are *good* gamblers/mathematically-literate, but thought this was a trick question about the existence of $1000 bills.
I *think* (and again, I know I'm new here so I don't mean to barge in and tell you good folks how to run things, but) the question needs to be removed from the pool of data and re-posted as a new question without the "bill" portion. Otherwise the engine can't be sure the respondents were answering the same question. For Hunch to work, I think it's probably important that questions only have one reasonable interpretation.
