题目选项分析

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?

【选项】Other than the possibility of a leak, there is no realistic pollution threat posed to the lake by the pipeline's construction.

选项是否正确?

Assumption题,方法之一取反取非,找否定句取反
取反后能否定结论,答案正确。
B答案取反后说除了泄露的可能性,pipeline的建设也会引起污染的问题,所以是有fears,而不是不无根据的groundless。
