Difficulty: HardEvaluating Whole-Essay Goals and Purpose

In 1856, eighteen-year-old chemist William Henry Perkin was attempting to synthesize quinine, a treatment for malaria, in his home laboratory in London. Instead of obtaining a clear drug, Perkin ended up with a dark, sludge-like residue. When he attempted to clean the flask with alcohol, the mixture turned a brilliant purple. Recognizing the potential of the vibrant hue, Perkin realized he had accidentally created the first synthetic organic dye, which he eventually named mauveine.

Prior to Perkin’s discovery, dyes were derived exclusively from natural sources like plants, insects, and minerals. Purple, historically harvested from the glands of Mediterranean sea snails, was so rare and expensive that it was reserved almost entirely for royalty. Mauveine transformed this landscape. Because it could be mass-produced in a laboratory at a fraction of the cost, purple fabric suddenly became accessible to the general public. Perkin quickly patented his process, secured financial backing, and built a factory to manufacture the dye, sparking a fashion craze across Europe.

Perkin’s success did more than just revolutionize fashion; it laid the foundation for the modern chemical industry. The methods used to synthesize mauveine demonstrated that valuable organic compounds could be engineered systematically from coal tar, a waste product of coal gas production. This breakthrough prompted researchers to develop synthetic colors, artificial pharmaceuticals, and new plastics. By transforming chemistry from a descriptive science to a creative, industrial enterprise, Perkin’s accidental residue reshaped the modern world.

Suppose the writer’s goal had been to write an essay demonstrating how an accidental laboratory discovery influenced both nineteenth-century European fashion and the trajectory of industrial chemistry. The essay successfully achieves this goal.

Answer: Answer

Answer

The statement is true because the essay successfully describes the accidental discovery of mauveine, its impact on European fashion, and its role in launching the modern chemical industry.
The statement is correct because the essay systematically addresses all components of the specified goal: the accidental nature of the discovery, the resulting European fashion craze, and the foundation it laid for the modern chemical industry.

Step-by-Step Solution

1
Analyze the proposed writing goal to identify the key elements required: (1) explaining how an accidental discovery was made, (2) showing its impact on nineteenth-century European fashion, and (3) showing its impact on industrial chemistry.
Three distinct criteria are established to evaluate the essay.
To evaluate the success of the essay, we must first break down the hypothetical goal into verifiable components.
2
Examine the passage to see if each identified element is addressed.
Paragraph 1 explains the accidental discovery of mauveine during an attempt to synthesize quinine. Paragraph 2 details the rise of mauveine in Europe, making purple fabric affordable and sparking a fashion craze. Paragraph 3 details how it laid the foundation for the industrial chemical industry, leading to synthetic pharmaceuticals and plastics.
Checking the text ensures that every part of the prompt's hypothetical goal is supported by the content.
3
Determine if the essay as a whole successfully achieves this goal based on the findings.
The essay successfully integrates and highlights all three elements, meaning the statement is true.
Since all components of the goal are thoroughly addressed and form the core narrative of the essay, the essay successfully achieves the goal.
