The following paragraphs are from an essay about the history of the pencil. To make the essay flow most logically, in what order should the paragraphs be placed?
- 1In 1564, a massive deposit of solid graphite was discovered in Borrowdale, England. Initially, locals utilized the dark, crumbly mineral to mark their sheep, unaware that they had stumbled upon the purest deposit of graphite ever found.
- 2Despite its usefulness, this raw graphite posed significant practical challenges. The material was not only brittle and prone to breaking but also left dark stains on the hands of anyone who held it, prompting craftsmen to wrap the graphite sticks in string or insert them into hollowed-out wooden sleeves.
- 3These early wooden casings successfully solved the handling issue, but the pencils still suffered from a lack of standard hardness. This final hurdle was overcome in 1795 when Nicolas-Jacques Conté patented a process of mixing powdered graphite with clay and firing it in a kiln, creating the customizable 'lead' we use today.
Cevap
The paragraphs should be ordered: first the paragraph describing the discovery of graphite in 1564, followed by the paragraph addressing the practical challenges of raw graphite and the introduction of wooden casings, and finally the paragraph discussing the limitations of early casings and the 1795 clay-mixture solution.
The correct order follows a logical chronological and thematic progression. The paragraph detailing the 1564 discovery of graphite establishes the context. The paragraph beginning with 'Despite its usefulness, this raw graphite...' transitions by explaining the drawbacks of the raw mineral and introduces wooden casings. The paragraph beginning with 'These early wooden casings...' uses a clear transitional phrase to link back to the casings and explains the final refinement in 1795.
