A recent survey of teenagers by the education advocacy group Common Core found that a quarter could not identify Adolf Hitler, a third did not know that the Bill of Rights guaranteed freedom of speech and religion, and fewer than half knew that the Civil War took place between 1850 and 1900. Roughly a third of all American high school students drop out.
