I found this underground passage of shops , one of which was devoted to Communism . The window displays argued that Communism was the best thing that ever happened to China , North Korea , Russia , etc . , and that The United States should switch over . There was even a flyer in which you could join the " East Bay Revolutionary Club " and attempt to take over the government .
According to the above context, answer the following question.
What may happen after finding the underground passages ?


It was full of communist propaganda .
