Very quickly, Dr. Murrow and Mr. Tirpak, there seems to be a contradiction in your presentations regarding the price of energy. Mr. Tirpak is saying China has it right by raising gasoline prices four times this year and a tax on gas guzzlers. Mr. Murrow, you seem to be talking about dropping prices of energy as you get efficiencies.
Maybe you can answer that through one of the other questions from one of the other people, because I'm out of time, I believe.
