What is the community's stance on people asking homework questions on the site?
There was a recent question that got me thinking about the issue; this question seems like a blatant copy & paste from a homework assignment, complete with multiple choices. There was no mention of it being homework (in the question body or tags).
Stackoverflow has had issues with this, and that community has adopted a policy of allowing such questions, as long as the asker is honest and upfront about it (i.e. mentioning that it is homework in the question body or tagging it [homework]). Askers are encouraged to list what they have tried thus far, prior to getting stuck and asking for help. Answerers then will try to give hints, but not answer the question directly.
It seems like a similar policy would make sense here, at least to me.
Another question, which could have been a homework question, was tagged as being from the GRE. In my opinion, the fact that the asker was upfront about the quesiton's source, and what, exactly, he/she was confused about, made this a good question. The first question does not strike me as particularly good.
