Final answer:
Upton Sinclair's "The Jungle" was a muckraking novel that prompted the enactment of both the Meat Inspection Act and the Pure Food and Drug Act due to its exposure of the unsafe and unsanitary practices in the meatpacking industry.
Step-by-step explanation:
The Pure Food and Drug Act and the Meat Inspection Act were the direct result of Upton Sinclair's novel “The Jungle.” This muckraking work exposed the unsanitary conditions and corrupt practices in the meatpacking industry, prompting widespread public outrage. President Roosevelt, influenced by the book's revelations and subsequent public pressure, established a commission whose findings supported Sinclair's accounts. Roosevelt then urged Congress to enact the Meat Inspection Act, which established federal inspection of meat products and cleanliness standards for meatpackers. Following this, the Pure Food and Drug Act was passed, requiring clear labeling of ingredients in both food and drugs and prohibiting the sale of adulterated foods and medicines, eventually leading to the creation of the U.S. Food and Drug Administration (FDA).
