I see no problem in folk asking for answers to questions whether it's two or ninety-two. I doubt may quiz-setters use only their own knowlede when setting a quiz and resort to the internet for questions or inspiration. Why then is it wrong for folk to use the internet to seek answers? There have been a fair few times when folk have come here to ask for answers and been given many different replies or none at all.
It is up to the person setting the quiz to use his or her skill in order to phrase the question in such a way as to make the search for the answer as easy or as difficult as they see fit.
