question: In what year was the clear and present danger test replaced?
short_answers: 1969
context: Following "Schenck v. United States", "clear and present danger" became both a public metaphor for First Amendment speech and a standard test in cases before the Court where a United States law limits a citizen's First Amendment rights; the law is deemed to be constitutional if it can be shown that the language it prohibits poses a "clear and present danger". However, the "clear and present danger" criterion of the "Schenck" decision was replaced in 1969 by "Brandenburg v. Ohio", and the test refined to determining whether the speech would provoke an "imminent lawless action".
