Which of the following was an effect of Upton Sinclair’s novel The Jungle?

The Jungle exposed unsanitary conditions in the meatpacking industry and helped spur federal food-safety reforms. Congress passed the Pure Food and Drug Act and the Meat Inspection Act in 1906; the Food and Drug Administration was later established to oversee food and drug safety. The novel did not cause riots or lead to Roosevelt’s impeachment, and factory inspections did not decrease.
