Q: proper question: The three page Kalven Report was issued in which year?
disfluent question: The three page Beadle uh Kalven Report was issued in which year?
context: The university experienced its share of student unrest during the 1960s, beginning in 1962, when students occupied President George Beadle's office in a protest over the university's off-campus rental policies. After continued turmoil, a university committee in 1967 issued what became known as the Kalven Report. The report, a two-page statement of the university's policy in social and political action, declared that To perform its mission in the society, a university must sustain an extraordinary environment of freedom of inquiry and maintain an independence from political fashions, passions, and pressures. The report has since been used to justify decisions such as the university's refusal to divest from South Africa in the 1980s and Darfur in the late 2000s.
