Question: The film is set in Igloolik in the Eastern Arctic wilderness at the dawn of the first millennium .  http://atanarjuat.com/legend/legend_film.php The wind is blowing over a bleak snowy landscape while a man tries to herd away some marauding dogs .  We hear the voice of an old man singing a childish song .  Inside a stone house a strange shaman by the name of Tungajuaq , who comes from up north , is singing playfully to the gathered community and camp leader Kumaglak .  But among the spectators there are some mistrustful faces .  Flash forward to another day .  Qulitalik is bidding goodbye to his sister Panikpak , wife of Kumaglak , promising to come if she calls for help in her heart .  She gives him her husband's rabbit's foot for spiritual power .  Qulitalik tells his sister , `` Tulimaq is the one they 'll go after now . ''  It seems that Qulitalik is leaving to escape a threat , and the hope is that one day he will return to help .  As Panikpak watches him leave , we hear a voice-over from a woman : `` We never knew what he was or why it happened .  Evil came to us like Death .  It just happened and we had to live with it . ''  Flash back to the original scene in the stone house .  The visitor and the camp leader Kumaglak are in a `` friendly '' spiritual duel involving binding in leather thongs .  But Panikpak is startled when the stone lamp in front of her breaks in half , and , to the horror of those present , Kumaglak falls over dead .  The visitor removes the leader's walrus-tooth necklace from Kumaglak's body , and , passing by Tulimaq , he puts the necklace around the neck of Sauri , the son of the murdered leader Kumaglak , saying , `` Be careful what you wish for '' . <sep>Did the visitor ever interact with Kumaglak?<sep>Friends

Question: You may be wondering, how can a glacier get so big? Why does it move? These are both good questions. In the winter months, precipitation falls as snow. This solid form of water builds up on the ground as long as the temperatures stay cold enough. As the temperature rises, the snow starts to melt. The frozen water changes state back into a liquid state. Nearer the poles, summer does not last very long. If the summer is long enough and warm enough, all the snow may melt. This is what typically happens now. The earth was a little cooler 12,000 years ago. As a result, during the summer months, that amount of snow did not melt. It may have only been an inch or so of snow that melted. The following winter, snow fell on top of this left-over snow. This next winters snowfall had a head start. Year after year, the snow that did not melt became thicker and thicker. Inch by inch the snow started to build up. Over many years, layer upon layer of snow compacted and turned to ice. <sep>How do glaciers form?<sep>Layer upon layer of snow compacted and turned to ice

Answer: Yes


Question: 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>What did Betty Ong report on her emergency call?<sep>Cockpit is not answering, someone is stabbed, and hijackers sprayed something

Yes
