Read the passage below:
Paragraph 1:
For much of the nineteenth century, historians of science attributed the rapid advancement of optical instruments during the Enlightenment primarily to theoretical breakthroughs in wave optics. According to this traditional narrative, formal mathematical modeling of refraction and diffraction directly enabled instrument makers to eliminate chromatic aberration in telescope lenses. Consequently, scholars viewed practical crafting as a mere downstream application of elite academic physics, assuming that workshops passively absorbed discoveries published by formal scientific academies.
Paragraph 2:
However, recent archival investigations into eighteenth-century artisan guilds challenge this top-down model. Re-examinations of workshop ledgers and personal correspondence reveal that practical lens grinders had empirically developed compound achromats—combining crown and flint glass to cancel color distortion��nearly two decades before mathematicians formulated the requisite wave equations. Rather than waiting for theoretical validation, these craftspeople relied on iterative physical testing, tacit trade knowledge, and trial-and-error adjustments. Thus, empirical workshop innovation preceded and actively stimulated academic inquiry, forcing theorists to adjust their optical models to account for functional artifacts already in circulation.
Paragraph 3:
This historical reassessment does not render theoretical physics irrelevant to the history of technology; rather, it suggests a reciprocal, dialectical relationship between theory and practice. While artisan experimentation initially drove instrument refinement, subsequent mathematical formalization by academic physicists allowed for the systematic optimization of lens curvature, extending optical performance far beyond what trial-and-error alone could achieve. Recognizing this bi-directional exchange provides a more nuanced framework for analyzing technological progress in the early modern era.
Which of the following best describes the function of the second paragraph of the passage?
- It presents historical findings that challenge the theoretical model described in the first paragraph and illustrates an alternative mechanism of technological development.Answer
- BIt provides technical details explaining how eighteenth-century craftspeople combined crown and flint glass to eliminate chromatic aberration in telescope lenses.
- CIt completely dismisses the role of academic physicists in early modern science by proving that theoretical optics contributed nothing to practical instrument design.
- DIt reconciles the conflicting theoretical perspectives presented in the preceding paragraph by proposing a unified framework for eighteenth-century science.
- EIt outlines the mathematical formulas formulated by Enlightenment scholars to systematically optimize lens curvature in workshop settings.
