Question

president roosevelt’s call to action upon reading upton sinclair’s the jungle is best described as
outrage toward the meat - packing industry, and imposing higher taxes on cattle farmers
disgust and anger toward meat - packing industry workers known as muckrakers
surprise at the public’s demand for healthy livestock, and continued disbelief of sinclair’s claims
movement to ensure sanitary conditions in meat - packing plants by signing new legislation

Explanation:

Upton Sinclair's The Jungle exposed unsanitary conditions in meat - packing plants. President Roosevelt, after reading it, took action to ensure sanitary conditions in these plants by signing new legislation (like the Meat Inspection Act and Pure Food and Drug Act). The first option is wrong as he didn't impose higher taxes on cattle farmers. The second is wrong as muckrakers were journalists exposing issues, not workers he was angry at. The third is wrong as he believed Sinclair's claims and acted on them.

Answer:

D. movement to ensure sanitary conditions in meat - packing plants by signing new legislation (assuming the last option is D, if the options were labeled A - D with the last one as D. If the original options had different labels, adjust accordingly, but based on the content, the correct description is the last option about signing new legislation for sanitary conditions in meat - packing plants)
