We've had a question about a homework tag before and the consensus was to not have one. However I'm a little bothered that we're getting questions that have absolutely no effort to answer from common sources (not just this site but e.g. Wikipedia or a simple web search). Some questions also do sound like straight "do my homework for me" requests (although not indicated as such).
So I'm asking for opinions on whether we should make an absence of effort to do prior research to try and answer a question a reason to close.
For example I'd suggest that "I checked Wikipedia but I don't quite get why X implies Y, please explain." would be fine (minimal effort and needs help understanding a concept) but "Name three X type objects" would not (no effort and a trivial web search gets the answer).
One objection (playing devil's advocate) is that we may discourage people genuinely trying to learn. In some ways this question is also asking to what extent we view Astronomy SE as a teaching site, I suppose. I confess I'm ambivalent about this.
Opinions ? Alternative ideas ?
Note : not suggesting adding a homework tag, just looking for a community consensus on certain types of questions.
