<p>"Obvious" homework?</p>

<ol>
<li>First, look at the questioner's SE network profile to see if the person is obviously a student or not.</li>
<li>If the person is not obviously a student, consider assuming good faith (as is <a href="https://en.wikipedia.org/wiki/Wikipedia:Assume_good_faith" rel="nofollow noreferrer">documented</a> on Wikipedia (and yes, I understand this is not Wikipedia)).</li>
<li>Consider just asking in a comment, "Is this for a course?"</li>
<li>Consider just ignoring the question for a while, because one thing is generally certain about homework:  It has a due date.  And after ignoring it for a while (a week?), and if nobody else has provided an answer, simply comment and ask, "Are you still looking for an answer?"  If the questioner doesn't respond within a few days, then perhaps it was homework, or in any case, the questioner must not care that much about an answer.</li>
