An usually severe winter occurred in Europe after the [#permalink]

An usually 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 Which of the following statements, if true, most seriously weakens the argument above? The cooling effect triggered by volcanic eruptions in 1985 was counteracted by an unusual warming of Pacific waters. There is a strong statistical link between volcanic eruptions and the severity of the rainy seasons in India A few months ago after El Chicn's large eruption in April 1982, air temperatures throughout the region remained higher than expected, given the long-term wather trends. The climatic effects of major volcanic eruptions can temporarily mask the general warming trend resulting from an excess of carbon dioxide in the atmosphere. Three months after an early springtime eruption in South America during the late 19th century, sea surface temperatures near the coast began to fall.

D seems like a viable option. Wait for your response. Thanks

I actually vote for D as well. What is the OA?

Which of the following statements, if true, most seriously weakens the argument above?
The cooling effect triggered by volcanic eruptions in 1985 was counteracted by an unusual warming of Pacific waters.
There is a strong statistical link between volcanic eruptions and the severity of the rainy seasons in India
A few months ago after El Chicn's large eruption in April 1982, air temperatures throughout the region remained higher than expected, given the long-term wather trends.
The climatic effects of major volcanic eruptions can temporarily mask the general warming trend resulting from an excess of carbon dioxide in the atmosphere.
Three months after an early springtime eruption in South America during the late 19th century, sea surface temperatures near the coast began to fall. tricky question its between c and d but i ll chose D in this case because C sites a very specific example which took place before the event (1984) mentioned in the question stem what is the OA for this one

The conclusion in this passage is based on evidence that severe winter occured after eruption of the Laki Volcano. But from C we know that another large eruption didn't make climate cooler (the same type of evidence but with different result). From this we can assume that it is not eruption made atmosphere to become cooler. So answer is C

Between C and D. I choose D. C still remains possibility of correct generalization if El Chicn's large eruption is an exception from many other eruptions. D goes deeply, saying severe winter cannot be an evidence.

Hey,  The argument is weak because it makes a generalization on the basis of only one example. Any example of a volcanic eruption that was not followed by a cooling of the atmosphere weakens this argument. The example of the eruption of El Chichon in 1982, which resulted in higher than normal air temperatures, contradicts the generalization of cooler temperatures following volcanic eruptions C Correct. This statement properly identifies a weakness in the argument OG11

The statement says nothing about Pacific waters. Eliminate it
There is a strong statistical link between volcanic eruptions and the severity of the rainy seasons in India
Nothing about rainy seasons. Eliminate it
A few months ago after El Chicn's large eruption in April 1982, air temperatures throughout the region remained higher than expected, given the long-term wather trends.
Correct! It's a proof that volcanic eruptions have nothing to do with atmosphere climate, or at least no direct correlation with a lower temperature.
The climatic effects of major volcanic eruptions can temporarily mask the general warming trend resulting from an excess of carbon dioxide in the atmosphere.
In my opinion, it supports the statement, since it says that the eruption could indeed have a impact on the climate.
Three months after an early springtime eruption in South America during the late 19th century, sea surface temperatures near the coast began to fall.
Nothing about sea temperatures

no reasoning gap in the argument hence a defender answer option requiring a third party element here. C does the same,comparing with a situation which didn't follow the rhetoric mentioned in the argument. Thus C.
