President roosevelt’s first reaction to upton sinclair’s the jungle is best described as outrage toward the meat-packing industry. disgust and anger toward meat-packing industry workers. surprise at the public’s demand for healthy livestock. disbelief and distrust of sinclair’s claims.

The correct answer is "Disbelief and distrust of Sinclair’s claims."

The jungle is a novel written in 1904 by American Journalist Upton Sinclair. It caused a lot of attention among the public at the time due to the fact that it exposed the harsh conditions that existed in the meat packing industry. However, President Theodore Roosevelt was highly skeptical of Sinclair's claims. He privately wrote to journalist William Allen White, expressing doubts about the accuracy of Sinclair's claims.
