Example Input: Clarifying the Record The defense of U.S. airspace on 9/11 was not conducted in accord with preexisting training and protocols. It was improvised by civilians who had never handled a hijacked aircraft that attempted to disappear, and by a military unprepared for the transformation of commercial aircraft into weapons of mass destruction. As it turned out, the NEADS air defenders had nine minutes' notice on the first hijacked plane, no advance notice on the second, no advance notice on the third, and no advance notice on the fourth. We do not believe that the true picture of that morning reflects discredit on the operational personnel at NEADS or FAA facilities. NEADS commanders and officers actively sought out information, and made the best judgments they could on the basis of what they knew. Individual FAA controllers, facility managers, and Command Center managers thought outside the box in recommending a nationwide alert, in ground-stopping local traffic, and, ultimately, in deciding to land all aircraft and executing that unprecedented order flawlessly. More than the actual events, inaccurate government accounts of those events made it appear that the military was notified in time to respond to two of the hijackings, raising questions about the adequacy of the response. Those accounts had the effect of deflecting questions about the military's capacity to obtain timely and accurate information from its own sources. In addition, they overstated the FAA's ability to provide the military with timely and useful information that morning. In public testimony before this Commission in May 2003, NORAD officials stated that at 9:16, NEADS received hijack notification of United 93 from the FAA. This statement was incorrect. There was no hijack to report at 9:16. United 93 was proceeding normally at that time. In this same public testimony, NORAD officials stated that at 9:24, NEADS received notification of the hijacking of American 77. This statement was also incorrect. The notice NEADS received at 9:24 was that American 11 had not hit the World Trade Center and was heading for Washington, D.C. In their testimony and in other public accounts, NORAD officials also stated that the Langley fighters were scrambled to respond to the notifications about American 77,178 United 93, or both. These statements were incorrect as well. The fighters were scrambled because of the report that American 11 was heading south, as is clear not just from taped conversations at NEADS but also from taped conversations at FAA centers; contemporaneous logs compiled at NEADS, Continental Region headquarters, and NORAD; and other records. <sep>Who handled the U.S. air defense on 9/11?<sep>9
Example Output: No

Example Input: Tom plays pool in a deserted pool hall , pocketing two balls by lowdown means and then wakes Jerry up by shooting the 10-ball into the pocket where he is sleeping . Jerry awakes just in time to avoid the 10-ball and is carried out to the ball return , where the 10 and the 13 smash the mouse between each other . Jerry is mad and walks up through the pocket , first sees nothing , but after a few steps back to the pocket , he spots Tom perched behind it . Jerry tries to jump into another corner pocket , but Tom aims a cue ball with so much force that it roll's into the pocket , and spins back out of it and it rolls Jerry backwards to Tom , who has made a ramp with his cue stick for the mouse to slide up . Jerry stops at the top of the stick and is then blown down by Tom , who then shoots a stream of balls to make the mouse flat . The whole train rebounds back towards the cat and the balls stack up at Tom's end of the table . Tom shoots all the balls in succession with his cue , and then tries to shoot Jerry , but the mouse hangs onto the cue tip . The cat , as if he were saying '' Have it your way '' , chalks up and shoots the 8-ball using Jerry . The mouse drops off the cue tip and then is upended by the 8-ball rolling in circles , and Tom forces Jerry to jump through the ball rack as if he were a circus performer . Tom then sets it on fire to add an additional level of torment , and when Jerry accomplishes this with poise , Tom discards the flaming rack and shoots the 8-ball across the table and back . <sep>Why did the mouse drop off the cue tip?<sep>Anything else
Example Output: No

Example Input: Mr. Andrews pointed to one of the oak chairs. "You sit there," he commanded, "it's reserved for members of the bar, but it's all right. You're with ME." Distinctly annoyed, slightly bewildered, the banker sank between the arms of a chair. He felt he had lost his individuality. Andrews had become his sponsor. Because of Andrews he was tolerated. Because Andrews had a pull he was permitted to sit as an equal among police-court lawyers. No longer was he Arnold Thorndike. He was merely the man "with Mr. Andrews." Then even Andrews abandoned him. "The judge'll be here in a minute, now," said the assistant district attorney, and went inside a railed enclosure in front of the judge's bench. There he greeted another assistant district attorney whose years were those of even greater indiscretion than the years of Mr. Andrews. Seated on the rail, with their hands in their pockets and their backs turned to Mr. Thorndike, they laughed and talked together. The subject of their discourse was one Mike Donlin, as he appeared in vaudeville. To Mr. Thorndike it was evident that young Andrews had entirely forgotten him. He arose, and touched his sleeve. With infinite sarcasm Mr. Thorndike began: "My engagements are not pressing, but" A court attendant beat with his palm upon the rail. "Sit down!" whispered Andrews. "The judge is coming." Mr. Thorndike sat down. The court attendant droned loudly words Mr. Thorndike could not distinguish. There was a rustle of silk, and from a door behind him the judge stalked past. <sep>Why was Arnold tolerated among the police-court lawyers?<sep>He was a banker
