[EX Q]: While the Base Ball writers of the cities which comprise the Southern Association have no organized membership similar to the Base Ball Writers' Association of the major leagues and the organizations which are best known as the class AA leagues, they are a clever, hard-working group of young men, who have labored in season and out of season, not only to build up Base Ball but to build it up on the right lines.  Experience of more than a quarter of a century has most abundantly proved that the standard of Base Ball has steadily been elevated.  It needs no compilation of fact nor any dogmatic assertion on the part of the Editor of the GUIDE to attest that fact.  It is a present condition which speaks for itself.  The general tone of the players is far higher than it was and there has come into evidence a marked improvement in the spirit of the men who own Base Ball clubs.  In the earlier history of the sport there was a tendency to win by any means that did not actually cross the line of dishonesty.  Later there came a season when the commercial end of the game tended to encroach upon the limits of the pastime.  This has been repressed in the last two seasons and to-day the morale of Base Ball is of a higher type than it ever has been in the history of the pastime. <sep>What characteristics of the pastime of baseball has been repressed?<sep>They are a clever and hard-working
[EX A]: No

[EX Q]: Static electricity is like a teeter-totter. What happens if a teeter-totter is balanced? Correct! It does not move. What about when its not balanced? Yes, it will now begin to move. Charges move when they are not balanced. Charges can build up by friction. Maybe you rub your feet on a wool mat or carpet. Rubber soled shoes readily gain charges. The wool carpet easily gives up charges. The two items become unbalanced. One item has a positive charge. The other has a negative charge. The difference in charge is called static electricity. Just like the teeter-totter, something is going to move. Positive charges build up on the mat. Negative charges build up on you. <sep>When static electricity is balanced like a teeter-totter, what happens?<sep>"It does not move."
[EX A]: Yes

[EX Q]: 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>Who jammed their way into the plane's cockpit?<sep>The airline workes
