Most geologists believe oil results from chemical transformations of hydrocarbons derived from organisms buried under ancient seas. Suppose, instead, that oil actually results from bacterial action on other complex hydrocarbons that are trapped within the Earth. As is well known, the volume of these hydrocarbons exceeds that of buried organ- isms. Therefore, our oil reserves would be greater than most geologists believe.
Which of the following, if true, gives the strongest support to the argument above about our oil reserves?
(A) Most geologists think optimistically about the Earth’s reserves of oil.
(B) Most geologists have performed accurate chem- ical analyses on previously discovered oil reserves.
(C) Ancient seas are buried within the Earth at many places where fossils are abundant.
(D) The only bacteria yet found in oil reserves could have leaked down drill holes from surface contaminants.
(E) Chemical transformations reduce the volume
答案
题干:geologists 认为 oil来自 古海底organisms的化学转化作者反驳:如果 oil来组 其他hydrocarbons的转化,而H的量远比O的量要大因此OIL的量要比前者预计的多明显可以看出,文章的逻辑线如下:H>OH产生的oil>O产生的...
