Difficulty: MediumSupporting Claims with Evidence and Details

The sentences below are from a draft of an essay about historical preservation. To ensure the paragraph logically builds its claim that optical scanning technologies safely retrieve sound from fragile wax cylinders, arrange the sentences in the most logical order.

  1. 1Historically, archivists struggled to preserve late nineteenth-century sound recordings on wax cylinders because playing them with a traditional stylus wears away the fragile grooves.
  2. 2In response to this preservation crisis, scientists developed a non-contact method using high-resolution optical scanners to image the delicate grooves.
  3. 3These detailed visual scans are then converted by computer algorithms into a three-dimensional digital model of the cylinder's surface.
  4. 4Ultimately, specialized software reads this digital model to recreate the audio, allowing listeners to hear the historic recordings without any physical contact.

Answer

The correct order of the sentences begins with the explanation of the fragile wax cylinders and traditional stylus wear, followed by the introduction of non-contact optical scanners, then the conversion of those visual scans into a three-dimensional digital model, and concludes with the software recreating the audio from the model.
The paragraph develops logically by first identifying the problem (stylus wear on fragile wax cylinders), introducing the technological solution (optical scanners), explaining the intermediate processing step (creating a three-dimensional model), and concluding with the final output (software recreating the audio).

Step-by-Step Solution

1
Identify the introductory sentence that sets up the context or claim.
The sentence describing the historical struggle to preserve wax cylinders due to physical stylus wear is the only logical start.
It introduces the topic and the central problem that the rest of the paragraph addresses.
2
Connect the problem to the proposed solution using cohesive transitions.
The sentence starting with 'In response to this preservation crisis' follows next, introducing the optical scanning method.
The phrase 'this preservation crisis' directly references the stylus damage described in the opening sentence.
3
Trace the step-by-step technological process.
The sentence about converting visual scans into a three-dimensional digital model follows the introduction of scanners.
The phrase 'These detailed visual scans' references the scans generated by the optical scanners in the second sentence.
4
Locate the concluding sentence that resolves the problem.
The sentence starting with 'Ultimately' comes last.
It uses the phrase 'this digital model' to refer to the model generated in the third step, and completes the explanation of how audio is safely retrieved.
