Complete Question Explanation
(See the complete passage discussion here: lsat/viewtopic.php?t=10866)

The correct answer choice is (A)

The author refers to Zanotto’s study in order to support the main conclusion of the passage, that the windows of some medieval churches are of uneven thickness not because of glass flow, but because of the glassmaking processes of the time.

Answer choice (A): This is the correct answer choice. In lines 39-43, the author remarks that Zanotto’s study “demonstrates dramatically what many scientists had reasoned earlier...” Clearly, then, the results of Zanotto’s study support a view that was already held by scientists.

Answer choice (B): The study is consistent with what many scientists had already suspected; it did not stimulate new research.

Answer choice (C): The study helps refute a common misconception, not explain that misconception.

Answer choice (D): The study does not help to reconcile two scientific views that had been thought incompatible. Rather, it introduces one scientific view that is incompatible with a popular belief.

Answer choice (E): Zanotto’s study helps to support the author’s conclusion; there is no suggestion that a puzzling phenomenon has not been adequately explained. On the contrary, the study provides a plausible explanation for the phenomenon discussed in the passage.
