Zorluk: KolayComprehending Explicit Comparisons and Contrasts

Passage:
In eighteenth-century glassmaking, artisans relied primarily on two methods to produce flat window glass: the crown glass method and the cylinder glass method. The crown glass technique involved blowing a globe of molten glass, flattening it, and spinning it rapidly to form a large, thin disk with a thick central bullseye. In contrast, the cylinder glass method required blowing a long glass cylinder, cutting it lengthwise, and flattening it on a hot iron plate. While crown glass boasted a remarkably smooth and brilliant surface because it was never touched by flattening tools, cylinder glass allowed glassmakers to manufacture significantly larger rectangular panes despite having a slightly rougher surface texture.

According to the passage, how did crown glass explicitly differ from cylinder glass regarding its physical quality?

  1. Crown glass possessed a smoother and more brilliant surface finish.Cevap
  2. B
    Crown glass could be crafted into much larger rectangular window panes.
  3. C
    Crown glass was flattened directly on a hot iron plate during production.
  4. D
    Crown glass acquired a slightly rougher texture due to the spinning process.

Cevap

Crown glass possessed a smoother and more brilliant surface finish.
The passage explicitly notes that crown glass had a remarkably smooth and brilliant surface because it was spun and never came into contact with flattening tools, whereas cylinder glass had a slightly rougher surface texture.

Adım Adım Çözüm

1
Identify the target entities and contrast criteria in the prompt.
The prompt asks for the explicitly stated difference in physical quality between crown glass and cylinder glass.
Locating where both terms are compared in the passage isolates the relevant facts.
2
Locate the explicit comparison sentence in the passage.
The text states: 'While crown glass boasted a remarkably smooth and brilliant surface because it was never touched by flattening tools, cylinder glass allowed glassmakers to manufacture significantly larger rectangular panes despite having a slightly rougher surface texture.'
This directly compares the surface quality of crown glass against cylinder glass.
3
Match the explicit statement to the correct choice.
The choice highlighting the smoother and more brilliant surface finish directly matches the text.
Literal comprehension requires identifying stated details without altering their meaning.
