Input: Read this: In 1992, the university drafted a new Statement on Academic Freedom, specifying that limitations may be placed upon "expression with students or in public that: (1) contradicts or opposes, rather than analyzes or discusses, fundamental Church doctrine or policy; (2) deliberately attacks or derides the Church or its general leaders; or (3) violates the Honor Code because the expression is dishonest, illegal, unchaste, profane, or unduly disrespectful of others." These restrictions have caused some controversy as several professors have been disciplined according to the new rule. The American Association of University Professors has claimed that "infringements on academic freedom are distressingly common and that the climate for academic freedom is distressingly poor." The new rules have not affected BYU's accreditation, as the university's chosen accrediting body allows "religious colleges and universities to place limitations on academic freedom so long as they publish those limitations candidly", according to associate academic vice president Jim Gordon. The AAUP's concern was not with restrictions on the faculty member's religious expression but with a failure, as alleged by the faculty member and AAUP, that the restrictions had not been adequately specified in advance by BYU: "The AAUP requires that any doctrinal limitations on academic freedom be laid out clearly in writing. We [AAUP] concluded that BYU had failed to do so adequately."
Question: How many professors have been disciplined according to the new Statement on Academic Freedom?

Output: several

Input: Read this: Once inside the Rotunda for the Charters of Freedom, there are no lines to see the individual documents and visitors are allowed to walk from document to document as they wish. For over 30 years the National Archives have forbidden flash photography but the advent of cameras with automatic flashes have made the rules increasingly difficult to enforce. As a result, all filming, photographing, and videotaping by the public in the exhibition areas has been prohibited since February 25, 2010.
Question: For how long has the National Archives prohibited flash photography?

Output: over 30 years

Input: Read this: Mastic asphalt is a type of asphalt which differs from dense graded asphalt (asphalt concrete) in that it has a higher asphalt/bitumen (binder) content, usually around 710% of the whole aggregate mix, as opposed to rolled asphalt concrete, which has only around 5% added asphalt/bitumen. This thermoplastic substance is widely used in the building industry for waterproofing flat roofs and tanking underground. Mastic asphalt is heated to a temperature of 210 C (410 F) and is spread in layers to form an impervious barrier about 20 millimeters (0.79 inches) thick.
Question: What is the usual thickness of the mastic spread on roofs?

Output: 20 millimeters

Input: Read this: Formerly, men not wearing military uniform wore knee breeches of an 18th-century design. Women's evening dress included obligatory trains and tiaras or feathers in their hair (or both). The dress code governing formal court uniform and dress has progressively relaxed. After World War I, when Queen Mary wished to follow fashion by raising her skirts a few inches from the ground, she requested a lady-in-waiting to shorten her own skirt first to gauge the king's reaction. King George V was horrified, so the queen kept her hemline unfashionably low. Following their accession in 1936, King George VI and his consort, Queen Elizabeth, allowed the hemline of daytime skirts to rise. Today, there is no official dress code. Most men invited to Buckingham Palace in the daytime choose to wear service uniform or lounge suits; a minority wear morning coats, and in the evening, depending on the formality of the occasion, black tie or white tie.
Question: What century were men's knee breeches forbidden at Buckingham?

Output:
unanswerable
