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.
(B) There is a strong statistical link between volcanic eruptions and the severity of the rainy season in India.
(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 South America during the late 19th century, sea surface
temperatures near the coast began to fall.
