The correct answer is "The government can limit speech that causes harm".
The outcome of United States vs The New York Times, where the Supreme Court ruled in favor of the The New York Times and let them publish classified Pentagon Papers, created a precedent that the government cannot restrict freedom of speech. However, during the outcome of United States vs Shenck, the Supreme Court ruled in favor of the government, as it considered that the words printed in the newspaper represented a "clear and present danger" to society.
