What do you think was the most important effect of the publication of the jungle

Based on historical perspective, the most important effect of the publication of The Jungle is that it "exposes the appalling working conditions in the meat-packing industry."

The Jungle was written by Upton Sinclair and released in 1906. The novel reveals the difficult situations and exploited lives of immigrants in Chicago and other industrialized areas in the U.S.

This publication led the US government to investigate the meatpacking industries and establish regulations.

Hence, in this case, it is concluded that the correct answer is "it exposes the appalling working conditions in the meat-packing industry."
