Input: When American 11 struck the World Trade Center at 8:46, no one in the White House or traveling with the President knew that it had been hijacked. While that information circulated within the FAA, we found no evidence that the hijacking was reported to any other agency in Washington before 8:46. Most federal agencies learned about the crash in New York from CNN. Within the FAA, the administrator, Jane Garvey, and her acting deputy, Monte Belger, had not been told of a confirmed hijacking before they learned from television that a plane had crashed. Others in the agency were aware of it, as we explained earlier in this chapter. Inside the National Military Command Center, the deputy director of operations and his assistant began notifying senior Pentagon officials of the incident. At about 9:00, the senior NMCC operations officer reached out to the FAA operations center for information. Although the NMCC was advised of the hijacking of American 11, the scrambling of jets was not discussed. In Sarasota, Florida, the presidential motorcade was arriving at the Emma E. Booker Elementary School, where President Bush was to read to a class and talk about education. White House Chief of Staff Andrew Card told us he was standing with the President outside the classroom when Senior Advisor to the President Karl Rove first informed them that a small, twin-engine plane had crashed into the World Trade Center. The President's reaction was that the incident must have been caused by pilot error. At 8:55, before entering the classroom, the President spoke to National Security Advisor Condoleezza Rice, who was at the White House. She recalled first telling the President it was a twin-engine aircraft-and then a commercial aircraft-that had struck the World Trade Center, adding "that's all we know right now, Mr. President." At the White House, Vice President Dick Cheney had just sat down for a meeting when his assistant told him to turn on his television because a plane had struck the NorthTower of the World Trade Center. The Vice President was wondering "How the hell could a plane hit the World Trade Center" when he saw the second aircraft strike the South Tower. Elsewhere in the White House, a series of 9:00 meetings was about to begin. In the absence of information that the crash was anything other than an accident, the White House staff monitored the news as they went ahead with their regular schedules.

Does the response "National Military Center of Command" correctly answer the question "What was the Vice president doing when he saw a second plane strike the South Tower and what did the rest of the White House staff do?"?

The little party in the cabin, so disastrously begun, finished, under the mellowing influence of wine and woman, in excellent feeling and with some hilarity. Mamie, in a plush Gainsborough hat and a gown of wine-coloured silk, sat, an apparent queen, among her rude surroundings and companions. The dusky litter of the cabin set off her radiant trimness: tarry Johnson was a foil to her fair beauty; she glowed in that poor place, fair as a star; until even I, who was not usually of her admirers, caught a spark of admiration; and even the captain, who was in no courtly humour, proposed that the scene should be commemorated by my pencil. It was the last act of the evening. Hurriedly as I went about my task, the half-hour had lengthened out to more than three before it was completed: Mamie in full value, the rest of the party figuring in outline only, and the artist himself introduced in a back view, which was pronounced a likeness. But it was to Mamie that I devoted the best of my attention; and it was with her I made my chief success.

Question: "What was the last act of the evening?"

Answer: "Drawing a picture of the people at the party"

You may wonder if there are other examples of static discharge. The answer is yes. Lightning is a form of static discharge. It is much more dramatic than what happens between you and the door knocker, but it is the same principle. You can see how it occurs in the following diagram and animation. You have no doubt seen lightning in a rainstorm. What does lighting have to do with static electricity? As it turns out, everything! During a rainstorm, clouds develop regions of different charges. This happens due to the movement of air molecules, water drops, and ice particles. The negative charges are concentrated at the base of the clouds. The positive charges are concentrated at the top. The negative charges repel electrons on the ground below. The ground then becomes positively charged. Over time the differences increase. Eventually the electrons are discharged. This is what we see as lightning. You can watch an awesome slow-motion lightning strike below.

Question: "Is lightning a form of static discharge?"

Response: "Agree"

Problem: Ratners Group PLC, a fast-growing, acquisition-minded London-based jeweler, raised its price for Seattle-based specialty jeweler Weisfield's Inc. to $57.50 a share, or $62.1 million, from $50 a share, or $55 million, after another concern said it would be prepared to outbid Ratners's initial offer. The other concern wasn't identified. Ratners's chairman, Gerald Ratner, said the deal remains of "substantial benefit to Ratners." In London at mid-afternoon yesterday, Ratners's shares were up 2 pence (1.26 cents), at 260 pence ($1.64). The sweetened offer has acceptances from more than 50% of Weisfield's shareholders, and it is scheduled for completion by Dec. 10. The acquisition of 87-store Weisfield's raises Ratners's U.S. presence to 450 stores. About 30% of Ratners's profit already is derived from the U.S.

Question: "Who caused Ratners to raise its price?"

Answer: "Another concern said it would be prepared to outbid Ratner's initial offer"

Question:
Magnets are able to place a force on certain materials. This force is called a magnetic force. The force a magnet exerts is a little different from the forces you may normally think about. You exert a force on a book when you lift it. You also exert a force on the pedals of your bicycle. In both those cases, those forces cause a change. The change you see in both these cases is called motion. Magnets, too, can produce change. They can produce motion just like you do. Unlike you, magnets do not have to touch something to exert a force. A magnetic force is exerted over a distance. Thats right, a magnet can push or pull certain items without ever touching them. Thats how the maglev train works. Do you know another type of force that does not require objects to touch? These forces are known as non-contact forces. Another type of non-contact force you may be familiar with is gravity. Gravity too can cause changes in motion. Gravity holds our moon in orbit without touching it. After reading the above, is "Non-Contact Force" the correct answer to the question "The force that holds our moon in place, is an example of what type of force?"? OPTIONS:
- no
- yes

Answer:
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: "Which gas is found in cleaning products?"

Response: "oxygen"
OPTIONS:
- no
- yes
