Reading the passage
The mistake runs from structure to behavior: glass lacks a fixed crystal arrangement, so people assume it must keep acting like a thick, slow-moving liquid. The author explains why that inference fails. Solid and liquid glass can resemble each other in atomic arrangement while differing thermodynamically.
Working the answers
- A
This reverses the structural fact behind the confusion. Glass is described as amorphous rather than crystalline; the mistaken inference concerns what that amorphous structure makes it do.
- BCorrect
This is the unsupported bridge: because glass has an amorphous structure, it must behave like a very viscous liquid even when solid. The first paragraph says cooled glass keeps that structure but acquires solid physical properties. The shared structure therefore does not justify the assumed liquid behavior.
- C
Manufacturing methods are discussed as the probable real cause of uneven panes. A belief that old and modern methods were similar is not identified as the source of the downward-flow misconception.
- D
The author does not attribute the myth to a comparison of medieval and modern transition temperatures. That is a different proposed assumption from confusing atomic arrangement with physical behavior.
- E
Thermodynamic dissimilarity is the author's corrective fact. The mistaken reasoning overlooks that difference; it does not arise from assuming the difference exists.
