A writer is editing an essay about early bridge engineering and has drafted the following paragraph:
James Finley, a judge in Pennsylvania, revolutionized transportation in by building the first modern suspension bridge. Finley utilized iron chains to support a level wooden deck, allowing heavy carriages to cross Jacob's Creek safely. Prior to Finley's design, suspension bridges were constructed from rope or vines, which dipped significantly in the center and were highly unstable in strong winds. Finley patented his design in , and he went on to write several influential pamphlets describing the structural engineering principles behind his bridge.
Should the writer keep or delete the underlined sentence?
- Keep it, because it establishes the historical context that highlights the significance of Finley's structural innovation.Cevap
- BKeep it, because it details the geographical regions where rope and vine bridges were traditionally built.
- CDelete it, because it shifts the focus from Finley's engineering contributions to ancient bridge-building materials.
- DDelete it, because it repeats information about transport safety that is mentioned earlier in the paragraph.
Cevap
Keep it, because it establishes the historical context that highlights the significance of Finley's structural innovation.
The correct option states that the sentence should be kept because it establishes the historical context that highlights the significance of Finley's structural innovation. The paragraph focuses on Finley's revolutionary bridge design, and contrasting it with the instability of prior designs helps the reader appreciate the importance of his invention.
