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. After reading the above, is "3" the correct answer to the question "How many people were stabbed on the flight?"?

Answer:
yes

Question:
Earths magnetic field helps protect Earth and its organisms. It protects us from harmful particles given off by the sun. Most of the particles are attracted to the north and south magnetic poles. This is where Earths magnetic field is strongest. This is also where relatively few organisms live. Another benefit of Earths magnetic field is its use for navigation. People use compasses to detect Earths magnetic north pole. Knowing this helps them tell direction. Many animals have natural 'compasses' that work just as well. Birds like the garden warbler in Figure 1.36 use Earths magnetic field. They use it to guide their annual migrations. Recent research suggests that warblers and other migrating birds have structures in their eyes. These structures let them see Earths magnetic field as a visual pattern. After reading the above, is "Use for Olympic Sports" the correct answer to the question "Name two benefits of Earths magnetic field."?

Answer:
no

Question:
For thousands of years, people have found fossils. The fossils caused curiosity about Earths past. How did these organisms live? What type of world did they live in? Fossils can tell us a lot about Earths history. In ancient times, fossils inspired myths and stories. These stories included tales of monsters and other incredible creatures. What type of creature do you know that could inspire such stories? Of course, dinosaur fossils were once mistaken for dragons bones. Two thousand years ago, people discovered fossils in China. At the time, they were thought to be dragon bones. We know now that these were not bones, but fossils. So what is the difference? After reading the above, is "Dragons" the correct answer to the question "What did these stories consist of?"?

Answer:
yes

Question:
On the previous evening,--March 12th,--the monotony of the camp had been unexpectedly disturbed by the arrival, from the direction of Salt Lake City, of a horseman completely exhausted by fatigue and cold, who proved to be no other than Mr. Kane, whose mission to the Mormons by way of California was at that time totally unknown to the army. The next morning he introduced himself to the Governor, was received as his guest, and remained in conference with him throughout the day. What was the character of their communication is unknown, except by inference from its results. When presented to Judge Eckels, on the following day, Mr. Kane exhibited to him the letters he bore from the President, and other letters, also, from Brigham Young, accrediting him as a negotiator in the existing difficulties. To General Johnston he showed nothing; nor did the Governor, to the knowledge of the camp, acquaint either that officer or any other person with the purport of his business. It was evident to everybody, however, that the Mormon leaders, conscious of their inability to resist the force by which they would be assailed so soon as the snow should melt upon the mountains, were engaged in an effort, of which Mr. Kane was the agent, to secure through the Governor, if possible, indemnity for their past offences, in consideration of acknowledgment of his authority. After reading the above, is "No" the correct answer to the question "Was the public explicitly made aware of the mission or business of Mr. Kane at any point?"?

Answer:
yes
