7. A methanol powered car produces CO₂ when it runs. Does that mean it is contributing to global warming? (A) No, if the methanol was produced from recently living biomass (B) Yes, if the methanol was produced from recently living biomass (C) Yes, if the methanol was produced from solar power (D) No, if the methanol was produced from natural gas. 8. The density of compressed natural gas is 60 grams per liter. If a car were powered by an engine that burned natural gas (similar to a gasoline engine), how large a compressed natural gas tank would it need to have the same range as a standard gasoline car? (A) about 3 times bigger than a standard car's gasoline tank (B) about the same as a standard car's gasoline tank (C) about 20 times bigger than a standard car's gasoline tank (D) about 10 times bigger than a standard car's gasoline tank
