我觉得C超级对啊 为什么不选呢

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.
C为什么不对！！？？

我觉得题目是要我们寻找他因，并排除。应该是B。 C重复了题目最后一句，并不是他因，所以不是最合适的，属于迷惑选项。

bc觉得都可以...不过b好像更直接? 直接说了除了leak之外的possibility

要是lz不错c是错的...我也杯具了 呵呵...

难道是c说了believe?

nn继续讲解下哈~ 帮顶~

恩，楼上美女正解。believe是个主观词。

比如：我相信我女友爱上我了。。。这只是我个人感觉。但，也许我女友已经劈腿了。

即使这个believe不算，C也说不过去。题干已经说了provided this technology is effective。 C直接反对结论了。 这不是削弱，是推翻。

嘿嘿~ 第1回得到"正解"的评价~ 呵呵 谢谢jbc啦~ 貌似咱俩用户名...

jbc同学的这个例子....好吧 意思理解了....

不过要是推翻不就更削弱了? 只是强力强力的削弱?

哪位高手给个  一锤定音   的答案

CB二者比，B好一些
C选项：即使排除楼上几位同学说的主观成分，实际C只能说明这种防漏措施很有效，能防漏。那么如果有其他原因呢，比如建设过程中造成的污染？明显，C无法支持，而B支持了。

补充一点，文章最后说了：provided this technology is effective, those fears are groundless.

也就是，原文已经说了这个防漏措施是有效的，C只是重复了原文的意思，没有能够排除他因

很想知道下，A 为什么不对呢？
A说除了管道建设造成的污染之外，没有其他新的污染源，这岂不是更符合题意吗？
