196.An unusually severe winter occurred in Europe after the continent was blanketed by a blue haze resulting from the eruption of the Laki Volcano in the Europeans republic of Iceland in the summer of 1984. Thus, it is evident that major eruptions cause the atmosphere to become cooler than it would be otherwise.
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.
(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.
有問題的是a/c兩個選項
og說:Choice a announces that certain eruption did have a cooling effect, so although an indenpendent warming effect counteracted the effect, the argument is support.
我選a;我想eruption都被抵銷了....
所以無法造成cooling effect
關於正確答案c;
題目中舉出1982的eruption來說明eruption會造成一種熱效應,可是...
題目中說明的是1985阿,就算1982會導致熱效應,也不代表1985的eruption會造成熱效應.....
我好像是awa中argument中毒太深,直覺的反射出"他例無法說明此例"
不懂中.....
請幫忙
