Final answer:
The passage of meatpacking standards due to the novel The Jungle is an example of a law passed due to the work of muckrakers.
Step-by-step explanation:
The example of a law passed due to the work of muckrakers is the passage of meatpacking standards due to the novel The Jungle.
The book, written by Upton Sinclair, exposed the unsanitary working conditions and business practices in the meatpacking industry.
This led to the passage of the Pure Food and Drug Act of 1906, which aimed to improve food safety and regulate the industry.
The muckraker's work helped create government agencies like the U.S. Food and Drug Administration (FDA) to ensure consumer protection.
