[問題]考古題 CR Form37-Q19

[jim9619]

Most geologists believe oil results from chemical transformations of hydrocabons derived from organisms buried under ancient seas.Suppose,instead,that oil actually results from bacterial action on other complex hydrocabons that are trapped within the Earth. As is well known,the volume of these hydrocabons exceeds that of buried organisms.Terefore,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 chemical analyses on previously discovered oil reserves.
(C)Ancient seats 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 of buried hydrocabons derived from organisms by roughly the same proportion as bacterial action reduces the volume of complex hydrocabons.

正確答案是(E)

這題一開始我看不懂
完全不懂
後來查了單字才大概知道在說些什麼
最後用了消去法
消掉了前四個答案
終於得到正確答案
但是左看右看就是不懂最後這個選項再說什麼~~
可以麻煩哪位高手解釋一下嗎??
順便說明一下如何的支持原題!!
感激不盡~~~

E選項是說明化學轉換消耗hydrocabon的比例相同
這樣子可以更加支持題目的結論...
不然如果透過bacterial action產生oil的方式,其消耗complex hydrocabon比較多的話,那麼即使其存量比較多,也可能造成實際產出的oil比較少!!
