QUESTION TEXT: The passage most helps to answer which one of…
DISCUSSION: On this type of question, the right answer will be something that you can literally point to in the passage. If you can’t do that, you’re guessing.
The wrong answers take terms from the passage, but terms that were just mentioned as asides. There is no information in the passage that will answer the questions in the wrong answers.
Familiar terms feel more “right” to the brain. This is a known psychological bias. Know that you should move through answers rapidly if you’re only considering them because a term feels familiar. Either find the term in the passage to prove the answer, or move on.
- Lines 46-49 show that the passage lumps all pre-19th century glass blowing into the same category. The author didn’t differentiate between 17th century and medieval techniques.
- CORRECT. The fourth paragraph covers this. One way that modern techniques differ is that modern window glass is made by floating liquid glass on molten tin (lines 55-56).
- The passage never mentions pre-medieval windows.
- The passage only mentions germanium oxide once, on lines 32-35. It’s given as an example of the fastest flowing glass. The author never says whether it’s used in churches.
The point of mentioning it was to show that even the fastest flowing glass is incredibly slow.
- Lines 35-36 say that there were impurities in medieval glass, but the passage doesn’t say how they got there.
