Difficulty: MediumMeeting Specific Rhetorical Goals

Passage Excerpt:

For decades, early audio recordings captured on wax cylinders remained silent, too fragile to be played by traditional styluses without being destroyed. In response, physicists developed the IRENE system, which uses non-contact optical scanning to create digital images of the grooves. The system then uses software to reconstruct the audio from these images, allowing listeners to hear long-lost voices.

Question:

Given that all the choices are true, which choice most effectively emphasizes the extreme precision of the optical scanning technology described in the passage?

  1. map the microscopic contours of the grooves with sub-micrometer accuracyAnswer
  2. B
    capture digital pictures of the grooves so that the data can be stored
  3. C
    record visual details of the grooves, these images are then processed
  4. D
    take photos of the grooves, which are eventually saved as files on a hard drive

Answer

map the microscopic contours of the grooves with sub-micrometer accuracy
The correct option most effectively emphasizes the extreme precision of the technology by using highly specific and detailed descriptors like 'microscopic contours' and 'sub-micrometer accuracy.'

Step-by-Step Solution

1
Analyze the prompt to identify the specific rhetorical goal.
The goal is to find the choice that most effectively emphasizes the 'extreme precision' of the optical scanning technology.
Understanding the precise criteria of the prompt is essential for evaluating the rhetorical suitability of each option.
2
Evaluate each option for grammatical correctness.
The option beginning with 'record visual details' contains a comma splice and is grammatically incorrect; all other options are grammatically sound.
Eliminating grammatically incorrect options narrows the choices to those that are syntactically valid.
3
Compare the remaining grammatically correct options against the specified rhetorical goal.
The option beginning with 'map the microscopic contours' uses the terms 'microscopic contours' and 'sub-micrometer accuracy,' which explicitly convey high-precision measurements. The other grammatically correct options ('capture digital pictures' and 'take photos of') use general descriptions that do not highlight precision.
Selecting the option that best fulfills the specified rhetorical goal ensures the correct answer is determined.
