Step-by-step explanation:
The subject of this question is History and the grade level is High School. In Upton Sinclair's novel The Jungle, he exposed the unsanitary practices of the beef packing industry during the early 20th century. Sinclair aimed to highlight the exploitative conditions endured by both consumers and workers in this industry under the Capitalist system.
Sinclair had noted, "I aimed at the public's heart, and by accident, I hit it in the stomach." This statement poignantly expresses the contrast between Sinclair's intentions and the public outcome his work influenced. Notwithstanding, The Jungle remains an iconic literary work and a testament to the power of writing as a catalyst for social reform.
