Difficulty: MediumMain Idea and Primary Purpose

Passage:
Historically, the acoustic design of performance halls relied almost exclusively on empirical rules of thumb and intuitive architectural imitation rather than rigorous physical principles. When Wallace Clement Sabine was tasked in the late 1890s with correcting the atrocious acoustics of Harvard University's Fogg Art Museum lecture hall, he instituted a systematic, quantitative methodology that transformed architectural acoustics from an imprecise craft into a formal branch of applied physics. By meticulously measuring the reverberation times of various rooms using a pipe organ stop and a stopwatch, Sabine derived an empirical equation relating a room's volume and total sound absorption to its reverberation time. While subsequent scholars have frequently portrayed Sabine’s work as a sudden, isolated breakthrough that instantly discredited traditional building methods, recent architectural historians argue that his acoustic equations actually formalized and quantified acoustic intuitions that master builders had successfully deployed for centuries. Thus, Sabine’s true contribution lay not in inventing acoustic awareness ex nihilo, but in providing a standardized mathematical framework that rendered traditional acoustic knowledge reproducible and scalable across modern architectural designs.

Which of the following best states the primary purpose of the passage?

  1. To reexamine a prevalent historical narrative regarding a scientific innovation by contextualizing it within a longer tradition of empirical practice.Answer
  2. B
    To detail the specific experimental apparatus and mathematical calculations Sabine used to determine reverberation times in the Fogg Art Museum.
  3. C
    To argue that master builders prior to the late nineteenth century possessed a formal mathematical understanding of reverberation time.
  4. D
    To demonstrate that nineteenth-century architectural acoustic design relied on flawed physical principles that Sabine’s equations entirely disproved.
  5. E
    To trace the chronological evolution of architectural acoustics from ancient performance spaces to modern concert hall engineering.

Answer

The primary purpose of the passage is to reexamine a prevalent historical narrative regarding a scientific innovation by contextualizing it within a longer tradition of empirical practice.
The passage centers on re-evaluating the traditional historical view of Wallace Clement Sabine's acoustic discoveries. Rather than framing his work as an isolated revolution that negated past methods, the author presents recent historiography demonstrating that Sabine formalized existing empirical practices into a scalable mathematical model.

Step-by-Step Solution

1
Analyze the passage structure and main thesis
The passage begins by contrasting early acoustic design (empirical rules of thumb) with Sabine's quantitative methodology. It then introduces a common scholarly view (Sabine as a sudden breakthrough) and presents the revised view of recent historians (Sabine formalized existing empirical intuitions).
Identifying the shift in argument reveals the author's primary objective.
2
Evaluate the author's conclusion
The concluding sentence emphasizes that Sabine's true contribution was providing a mathematical framework for traditional knowledge rather than inventing acoustic awareness from scratch.
The final sentence summarizes the core claim that unifies the passage's discussion.
3
Match the synthesized argument with the correct answer choice
The statement regarding reexamining a prevalent historical narrative by placing the innovation within a tradition of empirical practice aligns precisely with the author's main focus.
The primary purpose choice must reflect the overarching thesis rather than isolated details or extreme overstatements.
