Conclusion ;
Thus, it is evident that major eruptions cause the atmosphere to become cooler than it would be otherwise
option C gives an alternate reasoning and weakens the argument
A few months ago after El Chichón's large eruption in April 1982, air temperatures throughout the region remained higher than expected, given the long-term weather trends.
IMO C

C says "higher than expected". It doesn't mean that the temperature was high. What if the expectation was extremely low? The temperature can be low, but higher than expectation... no? Say, expectation was 10 degrees and it was actually 11 degrees; the temperature is low but higher than expected... Am I missing something?

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 European 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.
LV eruption created blue haze that covered Europe continent, which followed by severe winter. Conclusion: major eruption cause cooler atmosphere
Which of the following statements, if true, most seriously weakens the argument above? you need to attack the link "major eruption" -> "cooler atmosphere"
(A) The cooling effect triggered by volcanic eruptions in 1985 was counteracted by an unusual warming of Pacific waters. cooling effect is confirmed, so not weaken
(B) There is a strong statistical link between volcanic eruptions and the severity of the rainy seasons in India raining season is out of scope
(C) A few months after El Chichón's large eruption in April 1982, air temperatures throughout the region remained higher than expected, given the long-term weather trends. provide a couter example to break the link, large eruption actually caused temperature to go higher
(D) The climatic effects of major volcanic eruptions can temporarily mask the general warming trend resulting from an excess of carbon dioxide in the atmosphere. this kind of confirms that eruptions can cooler the atmopshere
(E) Three months after an early springtime eruption in South America during the late 19th century, sea surface temperatures near the coast began to fall. sea temperature is out of scope, and even it isn't this evidence coincides with "eruption drops temperature"
