OK this title made me laugh a bunch -- I also have no clue!! The website looks like it has a little countdown and you can follow the link once your testing time starts??

For this one, you can try picturing two points in time: Let's imagine May 1, 2010, and May 1, 2020. On May 1, 2010, there were 600 billion barrels of oil in reserve. In the last 10 years, we've sucked 100 billion barrels of oil out of these reserves, so the level would be at 500 billion. But! Choice E says, actually we've found exactly 100 billion barrels of oil that weren't extractable 10 years ago. So our reserves are the exact same as they were 10 years ago. Does that help at all?
