Is it okay to put a website address in my quiz, like in the Interesting Information, as long as knowing that website isn't necessary to get the question correct? For example, can I direct the quiz taker to a website to see a picture of what I'm talking about?
Also, for the quiz I'm writing, some quiz takers may end up thinking "How do you know that?" In this case, should I put the website down, to show where I got my information, even if that web page may be no longer there in, say, a year from now?
