GWD28-Q9

9. GWD28-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.

请问A怎么错了？

我觉得A属于无关选项

A为什么无关？求解释

题中关注的是这个pipeline，逻辑是technology可以阻止pipeline形成的污染，与其他new industrial development around the lake，无关

assumption的题目经常用not来补充条件

把老题顶出来 想问一下C为什么不对 GWD给的答案是B 但是我觉的C更贴近 C说没有其他原因会导致这个technology失效么
？？？？？？  求大侠解释一下

个人觉得C不是在assumption,更像在加强而且很主观的说
c翻译过来，是说没有理由去相信当在那个湖里安装管道的时候，防泄露的技术是不有效地。
不知道楼上能理解吗？

文章是说：只要防漏技术没问题 就没问题。'provided this technology is effective, those fears are groundless.'

C是在强调技术不会有问题，但可能会有其他因素让人fear，所以并不能支持 ‘只要防漏技术没问题，就保证不会出现其他问题‘

B应该是正确选项，防漏是唯一需要担心的问题

fears 的核心是pollution， 而非只有leak一种， 故B把其他可能性也排除了， 而C就算这技术木问题， 还有other pollution 的可能性

Therefore, provided this technology is effective, those fears are groundless. 题目都说了。只要是有效的。C说没有理由相信是无效的，不是就是原文结论的前提条件的重写么。所以不对。
B是正确的，因为取反说湖底还有其他的有毒的物质，如果建这条油管就会把以前的有毒物质露出来，还是会污染，这就削弱了。
而A取反除去这根油管，还有其他的工业会造成湖水污染。这个和题干无关啊，排除。
