What candle burns longer a red candle or a green candle?

Umm actually both candles are the same unless one is smaller or bigger than the other but the burn both the same amount of time.

No! Neither candles. They both burn shorter! This was a trick question told by my tour guide...There were two hints: It does not matter what color the candles are, and 2. There is a second meaning in one of the words.
