You are walking along, holding an umbrella for your wife. You approach a gate with an obstruction above. It is made of steel. Choose one:
a. You should lower the umbrella, close the umbrella, pass the umbrella through the gate and open it on the other side.
b. You should leave the umbrella open, pass it over the top of the obstruction and continue on the other side.
c. You should continue to hold the umbrella in the same position because a metal solid will pass through another metal solid unobstructed. It is a law of physics.
d. You should give the small umbrella to a Secret Service body guard and get a larger umbrella on the other side of the gate because the small one you are holding is woefully insufficient to cover your wife.
e. You should resign because you are too dumb to hold a public office.
