Which government action is most closely associated with efforts of murckrakers?

The government action most closely associated with the efforts of muckrakers is the implementation of regulatory reforms, particularly in the early 20th century during the Progressive Era. Muckrakers, through their investigative journalism, exposed corruption, unsafe working conditions, and the unsanitary practices of industries, prompting public outcry. This led to legislative actions such as the Meat Inspection Act and the Pure Food and Drug Act, which aimed to improve public health and safety standards. Their efforts significantly influenced public policy and government accountability.
