Question

Which choice best supports the claim that Quilotoa was not responsible for the Little Ice Age?

• A. Line 54549 ("Identifying the volcano responsible has been tricky.")
• B. Lines 96005 - 59626 ("Such a sudden onset pointed to a huge volcanic eruption injecting sulfur into the stratosphere and starting the cooling.")
• C. Lines 72736 - 17025 ("The researchers then began to reconstruct the formation of the large, 800-meter-deep caldera [a basin-shaped volcanic crater] that now sits atop the volcano.")
• D. Lines 62895 - 31324 ("But when Lavigne's team examined shards of volcanic glass from this volcano, they found that they didn't match the chemical composition of the glass found in polar ice cores, whereas the Samalas glass is a much closer match.")

Answer 1

The correct option is D Lines 62895 - 31324 ("But when Lavigne's team examined shards of volcanic glass from this volcano, they found that they didn't match the chemical composition of the glass found in polar ice cores, whereas the Samalas glass is a much closer match.")

Option D is the correct answer. In paragraph 8, the author explains how Lavigne’s team proved that Quilotoa’s eruption did not cause the Little Ice Age: “But when Lavigne’s team examined shards of volcanic glass from this volcano, they found that they didn’t match the chemical composition of the glass found in polar ice cores, whereas the Samalas glass is a much closer match.” These findings show that Samalas, not Quilotoa, was responsible for the onset of the Little Ice Age. Option A, B and C are incorrect as they focus on aspects other than what the question asks.
