Amsterdam is at an elevation of -12 feet, and Orlando has an elevation of 89 feet. How many feet below sea level is Amsterdam?

Amsterdam is ​ (a)   feet below sea level.

• 12
• -12
• 89
• -89

Answer explanation

When discussing something that is below sea level, the word "below" already makes it negative. So 12 below sea level means -12 feet of elevation.

If you say -12 feet below sea level, it actually means 12 feet above sea level! Double negative!
