題目:
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 if buried organism. Therefore, our reserves would be greater than most geologists believes.

Which of the following if true, gives the strongest support to the argument above about our oil serves.

A. Most geologists think optimistically about the Earth’s reserves of oil.
B. Most geologists have performed accurate chemical analysis 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 drills holes from surface contaminants.
E. Chemicals transformations reduce the volume of buried hydrocarbons derived from organisms by roughly the same proportion as bacterial action reduces the volume of other complex hydrocarbons.

The correct answer is E , I know that the first to the forth answer may not be correct, but I have no idea that why the answer E can support the conclusion.

那應該有form多少吧？就麻煩樓主改一下標題，以造福之後的人尋找 :smile

題目: chemical transformation產生的石油量 < bacteria作用產生的石油量
answer E: chemical transformation耗費的hydrocarbon = bacteria所耗費的hydrocarbon

A<B 則 A-C < B-C, 反之亦然 --> support

the geologist think that oil result from transfomation of hydrocarbon derived from organism ....

actually, the oil was derived from bacterial action on other complex hydrocarbons that are trapped within the earth....

So if you find the answer which can justify the bacterial action is more than organism

OR

the organism action is less than the bacterial action from the earth.....

you can support the argument

Oh, I think I know why the answer E is correct.
Thanks ;yes;
