In this question, the author clearly states they are asking because they don't know the answer and it's part of their homework for school. I love to answer questions when I can, but should there be any kind of "ethical" or "moral" standard to what should or shouldn't be answered? It seems kind of shady to help someone cheat. I'm sure it happens more often, but when the admission is in the body of the question, that's a different story.
I'm no high-ground holier-than-thou type, but it gave me pause and thought I'd ask what the community thought.
