标题: GWD-28-Q9

Early in the twentieth century, Lake
Konfa became very polluted. Recently fish populations have recovered as release of industrial pollutants has declined and the lake’s waters have become cleaner. Fears are now being voiced that the planned construction of an oil pipeline across the lake’s bottom might revive pollution and cause the fish population to decline again. However, a technology for preventing leaks is being installed. Therefore, provided this technology is effective, those fears are groundless.

The argument depends on assuming which of the following?

A: Apart from development related to the pipeline, there will be no new industrial development around the lake that will create renewed pollution in its waters.

B: Other than the possibility of a leak, there is no realistic pollution threat posed to the lake by the pipeline’s construction

C: There is no reason to believe that the leak-preventing technology would be ineffective when installed in the pipeline in Lake
Konfa.

D: Damage to the lake’s fish populations would be the only harm that a leak of oil from the pipeline would cause.

E: The species of fish that are present in Lake
Konfa now are the same as those that were in the lake before it was affected by pollution.

这道题到底是选A还是B呢。一个是小范围的一个是大范围的。我倾向于选B，因为A提到了原文未提到的范围啊~各位NN·

B吧~~A选项提到的是其他新的工业发展，与文中的conclusion是无关选型，文中的conclusion仅仅是就这个而论

A不对吧，原题目只是说the planned construction of an oil pipeline ，没有提到其他新工业的信息，所以A应该是irrelevant吧。
