Shortly after the Persian Gulf War, investigators reported that the area, which had been subjected to hundreds of smoky oil fires and deliberate oil spills when regular oil production slowed down during the war displayed less oil contamination than they had witnessed in prewar surveys of the same area.They also reported that the levels of polycyclic aromatic hydrocarbons (PAHs)-used as a marker of combustion products spewed from oil wells ignited during the war-were also relatively low, comparable to those recorded in the temperate oil-producing areas of the Baltic Sea.

Which one of the following, if true, does most to resolve the apparent discrepancy in the information above?
A Oil contaminants have greater environmental effects in temperate regions than in desert regions.
B Oil contamination and PAH pollution disspiate more rapidly in temperate regions than in desert regions.
C Oil contamination and PAH pollution disspiate more rapidly in desert regions than in temperate regions.
D Peacetime oil production and transport in the Persian Gulf result in high levels of PAHs and massive oil dumping.
E The Persian Gulf War ended before the oil fires and spills caused as much damage as originally expected.

答案 D

我是这样理解的：

文中说某场战争结束后不久，调查人员发现在那些战争期间遭受过石油着火和人为的石油泄漏事故地区的石油污染情况要比战前情况好，这些地区在战争期间石油产量下降。同时该地区在战争期间PAHs水平也同时期这个海上其他石油生产地区的水平要低。

D说和平时期的石油生产会造成the Persian Gulf地区PAHs维持高水平，同时会造成大量石油泄漏

我先表个态:
同意头上的意见
两个矛盾:油井起火泄漏 1. 污染却少了 2.PAH相对下降
D的解释比起其他几个更好,Peacetime这个词很是具有诱惑力
