C. The public was outraged over food safety instead of worker conditions.
Many people believe that Upton Sinclair's primary intention with "The Jungle" was to highlight the poor working conditions and the exploitation of workers in the meatpacking industry. However, the public reaction focused more on the unsanitary conditions in food production rather than on the plight of the workers themselves. This shift in focus led to significant food safety reforms, such as the Meat Inspection Act and the Pure Food and Drug Act, which were not necessarily what Sinclair had aimed to achieve.
