The hijackers attacked at 9:28. While traveling 35,000 feet above eastern Ohio, United 93 suddenly dropped 700 feet. Eleven seconds into the descent, the FAA's air traffic control center in Cleveland received the first of two radio transmissions from the aircraft. During the first broadcast, the captain or first officer could be heard declaring "Mayday" amid the sounds of a physical struggle in the cockpit. The second radio transmission, 35 seconds later, indicated that the fight was continuing. The captain or first officer could be heard shouting:" Hey get out of here-get out of here-get out of here." On the morning of 9/11, there were only 37 passengers on United 93-33 in addition to the 4 hijackers. This was below the norm for Tuesday mornings during the summer of 2001. But there is no evidence that the hijackers manipulated passenger levels or purchased additional seats to facilitate their operation. The terrorists who hijacked three other commercial flights on 9/11 operated in five-man teams. They initiated their cockpit takeover within 30 minutes of takeoff. On Flight 93, however, the takeover took place 46 minutes after takeoff and there were only four hijackers. The operative likely intended to round out the team for this flight, Mohamed al Kahtani, had been refused entry by a suspicious immigration inspector at Florida's Orlando International Airport in August. Because several passengers on United 93 described three hijackers on the plane, not four, some have wondered whether one of the hijackers had been able to use the cockpit jump seat from the outset of the flight. FAA rules allow use of this seat by documented and approved individuals, usually air carrier or FAA personnel. We have found no evidence indicating that one of the hijackers, or anyone else, sat there on this flight. All the hijackers had assigned seats in first class, and they seem to have used them. We believe it is more likely that Jarrah, the crucial pilot-trained member of their team, remained seated and inconspicuous until after the cockpit was seized; and once inside, he would not have been visible to the passengers.

Simply put, energy is the ability to a cause change. Energy can cause many types of change. Think about when you have a lot of energy. You are able to do a lot of things. When you dont have a lot of energy, you may sit around and do very little. A similar thing happens to particles of matter as energy is added. The more energy there is, the faster the particles of matter move. Energy is also the reason you are able to move around. In fact, matter is always in motion. It can even change from one form to another. For example, electrical energy can be converted into heat energy. You see this every time you use the toaster. Energy causes a change in matter when you lift your arm. Energy can be used to move matter. You use energy to take a step to move forward. Thanks to energy, your body moves. The energy of moving matter is called kinetic energy.

Question: "When you use energy to take a step forward, what is it called?"

OPTIONS:
- no
- yes

Answer: "Kinetic energy"

Response: yes

Physical properties include the state of matter. We know these states as solid, liquid, or gas. Properties can also include color and odor. For example, oxygen is a gas. It is a major part of the air we breathe. It is colorless and odorless. Chlorine is also a gas. In contrast to oxygen, chlorine is greenish in color. It has a strong, sharp odor. Have you ever smelled cleaning products used around your home? If so, you have probably smelled chlorine. Another place you might smell chlorine is at a public swimming pool. The chlorine is used to kill bacteria that may grow in the water. Other physical properties include hardness, freezing, and boiling points. Some substances have the ability to dissolve in other substances. Some substances cannot be dissolved. For example, salt easily dissolves in water. Oil does not dissolve in water.

Question: "What do physical properties include?"

OPTIONS:
- no
- yes

Answer: "boiling point"

Response: yes

Madame White Snake: East Asian Femme Fatale of Old The Chinese legend of Madame White Snake, the snake demon that takes human form and becomes the wife of a man, has exerted a lasting influence over East Asian folktales and fiction for centuries. Two quintessential novellas, "The Lust of the White Serpant" from Ugetsu Monogatari by the Japanese author Ueda Akinari and "Eternal Prisoner under Thunder Peak Pagoda" a traditional Chinese story, are both relatively complex and demonstrate not only the evolution of the White Snake figure to become a more believable human, but also what aspects may have given her enduring appeal. While both these stories are ostensibly morality tales about the dangerous beauty of this femme fatale, the true source of pleasure from these narratives is the femme fatale's transgressive behavior, not her eventual punishment for it. Early tales of Madame White Snake appeared in China as early as the Song Dynasty, and initially her portrayal was fairly direct, as a villainous demon who drains the life force out of her human husband. But over time, characterizations of her became more complex, and the persona of Madame White Snake became more sympathetic, and perhaps even a model of the ideal Confucian wife, particularly in "Pagoda". Whalen Lai notes, "She was a loving wife, a caring mother, rescuer of her family from the first flood, and, at that point, a general benefactor of man. She took on the virtues of a traditional Chinese female, particularly forbearance". But if she were really an ideal wife, why could she not live happily with her human mate? Her dangerous sexuality is the key. Femme fatale might seem an unusual term to apply to a character from pre-modern Chinese and Japanese literature who may exemplify the virtues of an ideal Confucian wife, since it is primarily associated with film characters, particularly those of the film noir genre. But this term, which is relatively speaking, a neologism (The earliest uses were around the beginning of the 20th century
