There are many types of sugar molecules. What you buy in the grocery store is mostly one type of molecule. Its purity is regulated by the FDA (in the USA). As such, there are certain quantities of impurities that are allowed. That being the case, you have to interpret the question. Yes, it is pure to a degree, since it meets FDA requirements. To say that the sugar is absolutely pure--that's another story. What is between the sugar crystals? Air, right? Is air pure? No, it is a mixture of several different gases. Practically nothing is absolutely pure.
If you feel that you can argue that point then say "No, sugar is not pure." otherwise accept that the question probably is asking if sugar fairly pure or pure to a standard and answer "Yes, sugar is pure. It says 'Pure Cane Sugar' right on the side of the bag."
