TASK DEFINITION: You need to read the given passage and construct a question about the information present in the passage. The question should be answerable from the passage. Most importantly, only those questions are allowed whose answers cannot be determined from a single sentence. Do not generate questions that require only a single sentence to answer. Instead, try to combine two sentences and create a question from that combination. Do not create open-ended questions, i.e., the answers to them cannot be found precisely from the information provided in the passage.
PROBLEM: Paragraph- Sent 1: About this time, Card, the lead Secret Service agent, the President's military aide, and the pilot were conferring on a possible destination for Air Force One.
Sent 2: The Secret Service agent felt strongly that the situation in Washington was too unstable for the President to return there, and Card agreed.
Sent 3: The President strongly wanted to return to Washington and only grudgingly agreed to go elsewhere.
Sent 4: The issue was still undecided when the President conferred with the Vice President at about the time Air Force One was taking off.
Sent 5: The Vice President recalled urging the President not to return to Washington.
Sent 6: Air Force One departed at about 9:54 without any fixed destination.
Sent 7: The objective was to get up in the air-as fast and as high as possible-and then decide where to go.
Sent 8: At 9:33, the tower supervisor at Reagan National Airport picked up a hotline to the Secret Service and told the Service's operations center that "an aircraft [is] coming at you and not talking with us."Sent 9: This was the first specific report to the Secret Service of a direct threat to the White House.
Sent 10: No move was made to evacuate the Vice President at this time.
Sent 11: As the officer who took the call explained, "[I was] about to push the alert button when the tower advised that the aircraft was turning south and approaching Reagan National Airport."Sent 12: American 77 began turning south, away from the White House, at 9:34.
Sent 13: It continued heading south for roughly a minute, before turning west and beginning to circle back.
Sent 14: This news prompted the Secret Service to order the immediate evacuation of the Vice President just before 9:36.
Sent 15: Agents propelled him out of his chair and told him he had to get to the bunker.
Sent 16: The Vice President entered the underground tunnel leading to the shelter at 9:37.
Sent 17: Once inside, Vice President Cheney and the agents paused in an area of the tunnel that had a secure phone, a bench, and television.
Sent 18: The Vice President asked to speak to the President, but it took time for the call to be connected.

SOLUTION: how much time elapsed between the time that the tower supervisor at reagan national airport contacted the secret service and the time that american 77 started turning south?

PROBLEM: Paragraph- Sent 1: According to the radar reconstruction, American 77 reemerged as a primary target on Indianapolis Center radar scopes at 9:05, east of its last known position.
Sent 2: The target remained in Indianapolis Center's airspace for another six minutes, then crossed into the western portion of Washington Center's airspace at 9:10.
Sent 3: As Indianapolis Center continued searching for the aircraft, two managers and the controller responsible for American 77 looked to the west and southwest along the flight's projected path, not east-where the aircraft was now heading.
Sent 4: Managers did not instruct other controllers at Indianapolis Center to turn on their primary radar coverage to join in the search for American 77.
Sent 5: In sum, Indianapolis Center never saw Flight 77 turn around.
Sent 6: By the time it reappeared in primary radar coverage, controllers had either stopped looking for the aircraft because they thought it had crashed or were looking toward the west.
Sent 7: Although the Command Center learned Flight 77 was missing, neither it nor FAA headquarters issued an all points bulletin to surrounding centers to search for primary radar targets.
Sent 8: American 77 traveled undetected for 36 minutes on a course heading due east for Washington, D.C. By 9:25, FAA's Herndon Command Center and FAA headquarters knew two aircraft had crashed into the World Trade Center.
Sent 9: They knew American 77 was lost.
Sent 10: At least some FAA officials in Boston Center and the New England Region knew that a hijacker on board American 11 had said "we have some planes."Sent 11: Concerns over the safety of other aircraft began to mount.
Sent 12: A manager at the Herndon Command Center asked FAA headquarters if they wanted to order a "nationwide ground stop."Sent 13: While this was being discussed by executives at FAA headquarters, the Command Center ordered one at 9:25.
Sent 14: The Command Center kept looking for American 77.
Sent 15: At 9:21, it advised the Dulles terminal control facility, and Dulles urged its controllers to look for primary targets.
Sent 16: At 9:32, they found one.
Sent 17: Several of the Dulles controllers "observed a primary radar target tracking eastbound at a high rate of speed" and notified Reagan National Airport.
Sent 18: FAA personnel at both Reagan National and Dulles airports notified the Secret Service.

SOLUTION: What was one of the mistakes besides the air traffic control search that lead to America 77 flying for 36 min. undetected?

PROBLEM: Paragraph- Sent 1: Appended to the last book, however, is a self-contained essay on aesthetics, which Durer worked on between 1512 and 1528, and it is here that we learn of his theories concerning 'ideal beauty'.
Sent 2: Durer rejected Alberti's concept of an objective beauty, proposing a relativist notion of beauty based on variety.
Sent 3: Nonetheless, Durer still believed that truth was hidden within nature, and that there were rules which ordered beauty, even though he found it difficult to define the criteria for such a code.
Sent 4: In 1512/13 his three criteria were function ('Nutz'), naive approval ('Wohlgefallen') and the happy medium ('Mittelmass').
Sent 5: However, unlike Alberti and Leonardo, Durer was most troubled by understanding not just the abstract notions of beauty but also as to how an artist can create beautiful images.
Sent 6: Between 1512 and the final draft in 1528, Durer's belief developed from an understanding of human creativity as spontaneous or inspired to a concept of 'selective inward synthesis'.
Sent 7: In other words, that an artist builds on a wealth of visual experiences in order to imagine beautiful things.
Sent 8: Durer's belief in the abilities of a single artist over inspiration prompted him to assert that "one man may sketch something with his pen on half a sheet of paper in one day, or may cut it into a tiny piece of wood with his little iron, and it turns out to be better and more artistic than another's work at which its author labours with the utmost diligence for a whole year.".

SOLUTION:
Which artist, in addition to Alberti, did Durer disagree with?
