Canadians like to think that although they are the junior partner in their trade relations with the United States, the 174 billion barrels of proven reserves in the oil sands of Alberta provide a powerful ace up their sleeve in any dealings with their energy-hungry neighbor.

[单项选择]Although you may think that bottled water is an option than tap, two new reports show that the store-bought stuff is actually less regulated than the water you get out of your tap almost for free.
The Food and Drug Administration (FDA．has little authority to regulate bottled brands, according to a U.S. Congressional report released recently.
While municipal water utilities are required to provide public reports for test results, bottle-water makers are not. So although you may pay a pretty penny for bottled water, that doesn’t mean it’s any better than what’s coming out of your tap. In fact, it could be worse and you’d never know it.
The new research is backed by a report from the Environmental Working Group (EWG). The nonprofit organization surveyed the labels and Web sites of nearly 200 popular bottle-water brands and found that less than 2 percent disclosed three facts that can affect safety: the water’s source, purification (净化) methods, and chemical pollutant (污染物质)
A. Most brands of bottled water are regularly tested.
B. Purification methods are reliable and adequate.
C. Bottled brands provide test results publicly.
D. Bottled water might contain more pollutants.
