Difficulty: MediumFulfilling Specific Rhetorical and Writing Goals

The following passage is about the early history of color photography:

In the early 1900s, chemist and photographer Sergey Prokudin-Gorsky embarked on a monumental project to document the vast Russian Empire. Recognizing that traditional black-and-white photography failed to capture the vibrant cultures and diverse landscapes of the region, he developed a specialized camera. This camera rapidly exposed three black-and-white glass plates through red, green, and blue filters. By projecting these plates using three corresponding light sources, he reconstructed full-color images. [1] The Tsar, Nicholas II, was so impressed by a demonstration of these images that he provided Prokudin-Gorsky with a specially equipped railroad car darkroom and the necessary travel permits to document the empire.

The writer wants to add a sentence at Point [1] that highlights the groundbreaking nature of Prokudin-Gorsky’s technological achievement before explaining the Tsar's reaction. Which choice most effectively fulfills this goal?

  1. This ingenious process yielded remarkably vivid, full-color photographs decades before color film became commercially available.Answer
  2. B
    Although the glass plates were fragile, Prokudin-Gorsky traveled thousands of miles across the empire to capture these images.
  3. C
    His method was entirely unique, it combined chemical engineering with artistic vision to create a new medium.
  4. D
    Because he hoped that his photographs would educate Russian school children about their country's diverse regions.

Answer

This ingenious process yielded remarkably vivid, full-color photographs decades before color film became commercially available.
The correct option is grammatically correct and directly satisfies the writer's goal of highlighting the pioneering and groundbreaking nature of Prokudin-Gorsky's technology. By noting that this process achieved full-color photos decades before commercial color film, it emphasizes the advanced state of his technology.

Step-by-Step Solution

1
Analyze the prompt to identify the specific rhetorical goal.
The goal is to highlight the groundbreaking nature of the color photography technology at Point [1].
This establishes the criteria for the correct choice.
2
Evaluate the grammar of each option.
The option beginning with 'His method was entirely unique' is a comma splice, and the option starting with 'Because he hoped' is a fragment, eliminating both on grammatical grounds.
ACT English requires all correct choices to be grammatically correct.
3
Compare the remaining grammatically correct options against the rhetorical goal.
The option about the process yielding images decades before commercial color film highlights technological innovation. The option about traveling thousands of miles focuses on logistics and physical effort, not technology.
The correct choice must satisfy the specific prompt criteria rather than general relevance.
