Points Earned: 1/1 Correct Answer: C
Your Response: C At current rates of use, and at prices not greatly higher than those of today: 6. Coal will run out in a century or so, and oil will run out in a century or so. A. Oil will run out in a century or so, and coal will run out in a few centuries. B. Oil will run out in a few centuries, and coal will run out in a few centuries. C. Coal will run out in a century or so, and oil will run out in a few centuries. D. Oil and coal will last much longer than a few centuries. E. There is lots more coal than oil; oil has this habit of floating on water, thus rising through rocks and escaping to the sea floor where the oil is “burned” for energy by bacteria or other creatures. The size of the resource, in coal, oil, or anything else, depends on the price, and how long the resource lasts depends on rate of use, which is increasing rapidly for fossil fuels. The idea that immense pools of oil are out there, undiscovered but easy to get, is pretty silly—oil companies are really smart, drilled the easy stuff early on, and are now running out of oil that can be drilled and produced at prices close to modern. Points Earned: 1/1 Correct Answer: B Your Response: B Among fossil fuels: 7. Oil is made by heating of woody plant material, and coal is made by heating of algae. A. Coal is made by heating of woody plant material, and oil is made by heating of different woody plant material. B. Oil is made by heating of algae, and coal is made by heating of different algae. C. Coal is made by heating of woody plant material, and oil is made by heating of algae. D. Oil is made by spraying WD-40 on duct tape, and coal is made by being bad so Santa delivers it to your stocking. E. Slimy algae gives slimy oil; chunky wood gives chunky coal. Works great. Duct tape and WD-40 are the quick-fix tool kit; if something moves but it shouldn’t, apply duct tape, and if something doesn’t move but it should, apply WD-40. None of you would be so bad as to merit coal in your stocking, but we presume Santa gets it from a mine somewhere. Points Earned: 1/1 Correct Answer: D Your Response: D You are the chief biodiversity officer for the National Park Service in the eastern US, responsible for maintaining as much diversity as possible, and your boss has told you to focus on maintaining biodiversity of things big enough to see with the naked eye (so you don’t need to worry about microorganisms). You have two parks, and enough money to buy some land. You may enlarge one park a good bit, enlarge both parks some, or buy a corridor connecting the two parks. All of the land for sale is now wilderness, but the land you do not buy is going to be paved for a super- mega-mall. You would be wise to: 8. Enlarge both parks some; each park has some diversity, and you want to enhance both. A.
