Problem - 4713
$\textbf{Mountain}$
Before Mt. Everest was discovered, what was the highest mountain on earth?
$\textbf{Answer}$
It is still Mt. Everest.
$\textbf{Note}$
Another way to look at this problem is that it is a riddle, not a knowledge test. Not many people know the name of the second highest mountain on earth. If the answer were the second highest mountain, then this problem would be a geographic contest question.
