A person walks into a room and notices that a picture is hanging crooked. Which of the responses below indicates that the person is an engineer?

1. The person straightens the picture.
2. The person ignores the fact that the picture is crooked.
3. The person buys a CAD system and spends the next six months designing a solar-powered, self-adjusting picture frame while often stating aloud that the inventor of the nail was a total moron.

The correct answer is "C" but partial credit can be given to anybody who writes "It depends" in the margin of the test.
