Difficulty: MediumMeeting Specific Rhetorical Goals

Passage Excerpt:
In 1856, while attempting to synthesize quinine to treat malaria, eighteen-year-old chemist William Henry Perkin accidentally created mauveine, the world’s first synthetic organic dye. At the time, purple clothing was a status symbol affordable only by the extremely wealthy because natural purple dyes were harvested from rare sea snails. [1]

The writer wants to add a sentence at point [1] that contrasts the traditional difficulty of obtaining purple dye with the ease and affordability introduced by Perkin's synthetic alternative. Which choice best accomplishes this goal?

  1. A
    Perkin patented his discovery, he quickly established a factory to mass-produce the new dye.
  2. Unlike the laborious extraction process from snails, Perkin's synthetic method produced a vibrant, inexpensive color that could be easily mass-manufactured.Answer
  3. C
    Perkin patented his discovery and quickly established a factory to mass-produce the new dye.
  4. D
    The color purple had long been associated with royalty and wealth in various empires across the globe.

Answer

Unlike the laborious extraction process from snails, Perkin's synthetic method produced a vibrant, inexpensive color that could be easily mass-manufactured.
The correct option successfully fulfills the rhetorical goal by contrasting the traditional difficulty of obtaining purple dye (the laborious extraction process from snails) with the ease and affordability of Perkin's synthetic alternative (an inexpensive color that could be easily mass-manufactured).

Step-by-Step Solution

1
Analyze the prompt's rhetorical goal.
The target sentence must contrast the traditional difficulty of obtaining purple dye (sea snails) with the ease and affordability of Perkin's synthetic alternative.
This establishes the exact criteria the correct option must meet.
2
Evaluate the choices for grammatical correctness.
The option containing a comma splice is eliminated due to its grammatical error.
ACT English questions require the correct choice to be both grammatically correct and rhetorically appropriate.
3
Evaluate the remaining choices against the rhetorical goal.
Only the option beginning with 'Unlike the laborious extraction...' provides both sides of the contrast requested.
Other grammatically correct options discuss unrelated historical context or subsequent business operations without contrasting the old and new methods.
