问题 The passage gives a general description of the benefits and potential problems of a hydrogen economy.
An oil spill can pose a big problem to the environment.
选项 A、Y
B、N
C、NG
答案A
解析 本句讲oil spill对environment的害处，因此定位在problems with the fossil fuel economy处。矿物燃料经济有四大问题，再查找与environment相关的内容．即environmental pollution处。根据An oil spill，...can create a huge mess，可知本句正确，a huge mess与a big problem为同义转述。针对细节题，考生需要找出题干中的关键词。然后通过关键词对原文中的相关内容进行定位，先定位到小标题，然后进一步查找有无答案出处。
