问题     Of course, there is far more oil underground than can be recovered. It may be in a pool too small or too far from a potential market to justify the expense of drilling. Some oil lies under regions where drilling is forbidden, such as national parks or other public lands. Even given the best extraction techniques, only about 30 to 40 percent of the oil in a given pool can be brought to the surface. The rest is far too difficult to extract and has to remain underground. [br] According to paragraph 5, the decision to drill for oil depends on all of the following factors EXCEPT
选项 A、permission to access the area where oil has been found
B、the availability of sufficient quantities of oil in a pool
C、the location of the market in relation to the drilling site
D、the political situation in the region where drilling would occur
答案 D
解析
