Which is the Original?Logic puzzles require you to think. You will have to be logical in your reasoning.

HintThe copies and the original were exactly alike, the paper was the same color, and he made no markings to any of them.
AnswerThe new copies were warm as they had just been printed, while the original copy was room temperature.
