Passage One

Question 57 to 61 are based on the following passage.

Global warming may or may not be the great environmental crisis of the 21st century, but- regardless of whether it is or isn't - we won't do much about it. We will argue over it and may even, as a nation, make some fairly solemn-sounding commitments to avoid it. But the more dramatic and meaningful these commitments seem, the less likely they are to be observed. A1 Gore calls global warming an "inconvenient truth," as if merely recognizing it could put us on a path to a solution. But the real truth is that we don't know enough to relieve global warming, and - without major technological breakthroughs - we can't do much about it.
