An unusually severe winter occured in Europe after the continent was blanketed by a blue haze resulting from the eruption of the Laki Vocanal in the European Republic of Iceland in the summerof 1984. Thus, it is evident that major eruption cause the atmosphere become cooler tham it would be otherwise.
Which of the following statement, if true, most seriously weaken the argumnet above?
D: The climatic effects of major volcano eruption can temporarily mask the general warming trend resulting from an excess of carbon dioxide in the atmosphere.
答案 不是这个,og 给的解释说这句话实际上是加强了。我觉得应该是削弱了。题目说火山喷发能让天气变冷。可是这句话说火山喷发能让天气变暖,而且还给出了原因。

mask the warming trend是掩饰了持续的增温趋势,说明覆盖层会使气温降低

偶也是D不懂。
1、temporarily这个词会不会对选项造成影响?如果没有这个词,这道题目就没得说了,肯定不选。如果有了,就觉得模模糊糊的……
mindfree说逻辑是没有模糊选项的,只有对和错。晕晕的……
2、D说the climatic effects of major eruptions can mask the warming trending resulting from an excess of carbon dioxide in the atmosphere。在这里climatic effects and warming trend都是火山爆发引起的吗?
如果是,那火山爆发从长远看会有warming trend,但是暂时temporarily会被climatic effect掩盖……越来越觉得可以waken
谢谢牛牛

Which of the following statements, if true, most seriously weakens the argument above?
(A) The cooling effect triggered by volcanic eruptions in 1985 was counteracted by an unusual warming of Pacific waters.
(B) There is a strong statistical link between volcanic eruptions and the severity of the rainy season in
(C) A few months after EI Chichon’s large eruption in April 1982, air temperatures throughout the region remained higher than expected, given the long-term weather trends.
(D) The climatic effects of major volcanic eruptions can temporality mask the general warming trend resulting from an excess of carbon dioxide in the atmosphere.
(E) Three months after an early springtime eruption in
想请教一下A,这种先承认是Cooler,然后再给出一个例外算什么?如果存在例外的话就不应该是说可以降温,但是又先把前提承认一下,不懂这是什么逻辑,谢谢大家!!!
A:由于火山喷发引起的气温下降被一股不寻常的暖流给抵消了。--说的是火山喷发后的事情,跟火山喷发会不会引起气温下降没有关系。而且一开始也说明了,火山喷发的确是引起了气温下降,至于这个下降会不会被其他因素中和,不是问题的key。
D:抛弃修饰成分,光看主干:火山喷发mask了暖流。说明火山喷发会引起气温下降,加强。

抛弃修饰成分,光看主干
多谢,这个可能是做逻辑时都可以采用的技巧。
跟原文的事件是没关系。但跟结论有关系呀:
Thus, it is evident that major eruptions cause the atmosphere to become cooler than it would be otherwise.
C提供了一个反例,火山爆发后反而升温的,所以是weaken.
我觉得D才是真正的Weaken, 火山喷发的气候效果暂时掩盖了由于二氧化碳增加造成的气候变暖,也就是说实际上火山喷发会造成气候的变暖的。
(D)掩盖了warming的效果,只可能是cool才会有掩盖变暖效果
所以D项事实上是加强了结论
个人觉得OG的解释还是值得好好推敲地
我觉得要weaken的话可以预判的结果是这种降温的效果不是由火山爆发造成的,C这样的weaken似乎不是很强,也使D成了很强的干扰项,但从意思上看D确实是加强,但如果是考试,赶时间不好好推敲的话,选D的可能性很大的。

“要weaken的话可以预判的结果是这种降温的效果不是由火山爆发造成的”,偶觉得C符合了这一点的,weaken作用挺强的阿,选项提供了另外一个火山喷发的证据,显示喷发后气温升高。原题+提干所提供的证据表现火山喷发的影响不稳定,就不能说是火山喷发造成降温,只是你的预判思路可能部分落空,因为确实可以否定原因,但没有提供具体其他原因。一点拙见。
C也是有问题的。他只说remained higher than expected。
例如,火山喷发前,该地区平均温度30°,喷发后,专家们expected温度会降到20°,但是实际上却维持在25°,也就是remained higher than expected。这样的话,也说明了火山喷发是降低了温度的。
所以觉得C也不太严谨。

Which of the following statements, if true, most seriously weakens the argument above?
(A) The cooling effect triggered by volcanic eruptions in 1985 was counteracted by an unusual warming of Pacific waters. (Support cooling effect)
(B) There is a strong statistical link between volcanic eruptions and the severity of the rainy season in
(C) A few months after EI Chichon’s large eruption in April 1982, air temperatures throughout the region remained higher than expected, given the long-term weather trends.
(D) The climatic effects of major volcanic eruptions can temporality mask the general warming trend resulting from an excess of carbon dioxide in the atmosphere.(support cooling effect)
(E) Three months after an early springtime eruption in
Exclude A B D E , then I choice C.

这个推理有偷换概念之嫌,狡辩
A:由于火山喷发引起的气温下降被一股不寻常的暖流给抵消了。--说的是火山喷发后的事情,跟火山喷发会不会引起气温下降没有关系。而且一开始也说明了,火山喷发的确是引起了气温下降,至于这个下降会不会被其他因素中和,不是问题的key。
D:抛弃修饰成分,光看主干:火山喷发mask了暖流。说明火山喷发会引起气温下降,加强。
我觉得题目明显的写着“become cooler”---也就是降温,比如由原来的50度降到20度
而且D: maske the general warming trend掩盖了变暖的趋势----也就是说没有变暖了(意思说变冷或者没变),但是也没有只说变冷啊become cooler,
我已开始也认为D没错误,但是仔细推敲原文“become cooler”和D 的“mask the general warming trend”不构成削弱, D有点加强的意思。
只是我个人的理解
