The correct answer to this open question is the following.
Although there are no options attached we can say the following.
Newspapers frequently ran articles about anarchists and the threats posed by "radicals" in 1919 and 1920. The newspapers were interested in running these kinds of stories because these are sensationalists newspapers that love to create more drama and fear with their stories. The more drama the more people wanted to buy the newspaper to read the news. That has been one of the unofficial precepts of "Yellow Journalism," or sensationalistic news: caught people´s attention through drama.
How might this have influenced the Palmer Raids?
Heavily. That kind of news coverage generated fear in American citizens who were scared about the presence of anarchists and communists in the United States.
The main effect of the Palmer Raids was that they brought about the end of the red scare by clearing several supposed radicals. US President Woodrow Wilson ordered Attorney General Michael Palmer to execute the Palmer Raids to imprison anarchists and communists.
