The Phonautograph's Silent Legacy

[1]
__________________________________________________ Scott's device utilized a horn to focus sound waves onto a flexible diaphragm, which was connected to a stylus that etched visual waveforms onto soot-coated paper or glass. Crucially, the phonautograph lacked any mechanism to play back the recorded sound; Scott intended for these visual tracings, or "phonautograms," to be deciphered and read by eye. It was not until 2008 that researchers successfully used digital imaging technology to play back Scott's 1860 recording of the French folk song "Au Clair de la Lune," revealing the oldest recorded human voice in history.

Which of the following choices, if inserted into the blank at the beginning of the passage, would provide the most effective introduction to the passage as a whole?

  1. A
    Although French inventor Édouard-Léon Scott de Martinville patented the phonautograph in 1857 as the earliest known device for recording sound.
  2. B
    In 1857, the phonautograph was patented as the first sound recorder, Scott de Martinville did not intend for the machine to play music.
  3. In 1857, French inventor Édouard-Léon Scott de Martinville patented the phonautograph, the earliest known device for recording sound, though it was not designed for playback.Cevap
  4. D
    By the late nineteenth century, Thomas Edison had developed the phonograph, which transformed the music industry by allowing people to listen to commercial recordings in their homes.

Cevap

In 1857, French inventor Édouard-Léon Scott de Martinville patented the phonautograph, the earliest known device for recording sound, though it was not designed for playback.
The correct option is grammatically correct and introduces the historical significance of the phonautograph as well as its lack of playback capability. This establishes the thesis of the passage and leads directly into the details of the device's mechanism in the sentences that follow.

Adım Adım Çözüm

1
Analyze the passage to determine the primary topic and thematic development.
The passage discusses the invention, mechanics, and visual nature of Scott de Martinville's phonautograph, concluding with the recent digital retrieval of its audio.
Identifying the central theme is necessary to evaluate which introductory sentence aligns with the content.
2
Check the options for grammatical errors, specifically focusing on sentence structure.
The option beginning with 'Although' is a dependent clause fragment. The option beginning with 'In 1857, the phonautograph was patented...' contains a comma splice.
Eliminating grammatically incorrect choices helps narrow down candidates to those that are syntactically sound.
3
Compare the remaining grammatically correct choices for relevance to the passage's thesis.
The option discussing Thomas Edison introduces an off-topic comparison that disrupts the paragraph's focus. The option beginning with 'In 1857, French inventor...' correctly establishes the phonautograph as the subject and flows logically into the subsequent description of Scott's device.
An effective introduction must establish the thesis and transition smoothly into the body of the passage.
