Why can't I drink this chocolate?

• A. It's too cold.
• B. It's too hot.
• C. It tastes sour.
• D. It is spoiled.

Answer: (B)

Being too hot is the reason you can’t drink it right away. When a beverage is very hot, it can burn your mouth and throat, causing pain or injury, so it’s safer to let it cool first. The other problems—being too cold, tasting sour, or being spoiled—are undesirable, but they don’t pose the immediate safety risk that heat does. So the chocolate is too hot.
