Rule #3

Stick to the Facts

Do not include trivial information - the only intention of which is to confuse the test taker. For instance: Bob and Ed left their office on K Street in Washington DC at 4:45 pm to travel to BWI airport for a 9:00 pm flight - how far is the airport from their office? The times given have nothing to do with the correct answer; in fact, Bob and Ed are irrelevant, too. 4

A better phrased question would be:

Using (a calculator, a map, an internet site) calculate the distance between K Street in downtown DC and the BWI airport.
