Input: Consider 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

Output: No


Input: Consider Input: There have been many organisms that have lived in Earths past. Only a tiny number of them became fossils. Still, scientists learn a lot from fossils. Fossils are our best clues about the history of life on Earth. Fossils provide evidence about life on Earth. They tell us that life on Earth has changed over time. Fossils in younger rocks look like animals and plants that are living today. Fossils in older rocks are less like living organisms. Fossils can tell us about where the organism lived. Was it land or marine? Fossils can even tell us if the water was shallow or deep. Fossils can even provide clues to ancient climates. <sep>Name two things fossils can tell us about the enviroment?<sep>Tell us if the water was shallow or deep

Output: Yes


Input: Consider Input: We do not know exactly how the hijackers gained access to the cockpit; FAA rules required that the doors remain closed and locked during flight. Ong speculated that they had "jammed their way" in. Perhaps the terrorists stabbed the flight attendants to get a cockpit key, to force one of them to open the cockpit door, or to lure the captain or first officer out of the cockpit. Or the flight attendants may just have been in their way. At the same time or shortly thereafter, Atta-the only terrorist on board trained to fly a jet-would have moved to the cockpit from his business-class seat, possibly accompanied by Omari. As this was happening, passenger Daniel Lewin, who was seated in the row just behind Atta and Omari, was stabbed by one of the hijackers-probably Satam al Suqami, who was seated directly behind Lewin. Lewin had served four years as an officer in the Israeli military. He may have made an attempt to stop the hijackers in front of him, not realizing that another was sitting behind him. The hijackers quickly gained control and sprayed Mace, pepper spray, or some other irritant in the first-class cabin, in order to force the passengers and flight attendants toward the rear of the plane. They claimed they had a bomb. About five minutes after the hijacking began, Betty Ong contacted the American Airlines Southeastern Reservations Office in Cary, North Carolina, via an AT&T airphone to report an emergency aboard the flight. This was the first of several occasions on 9/11 when flight attendants took action outside the scope of their training, which emphasized that in a hijacking, they were to communicate with the cockpit crew. The emergency call lasted approximately 25 minutes, as Ong calmly and professionally relayed information about events taking place aboard the airplane to authorities on the ground. At 8:19, Ong reported:"The cockpit is not answering, somebody's stabbed in business class-and I think there's Mace-that we can't breathe-I don't know, I think we're getting hijacked." She then told of the stabbings of the two flight attendants. At 8:21, one of the American employees receiving Ong's call in North Carolina, Nydia Gonzalez, alerted the American Airlines operations center in Fort Worth, Texas, reaching Craig Marquis, the manager on duty. Marquis soon realized this was an emergency and instructed the airline's dispatcher responsible for the flight to contact the cockpit. At 8:23, the dispatcher tried unsuccessfully to contact the aircraft. <sep>How does Ong suspect the hijackers gained access to the cockpit?<sep>They used a key


Output: No
