Example Input: Paragraph- Sent 1: 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.
Sent 2: Ong speculated that they had "jammed their way" in.
Sent 3: 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.
Sent 4: Or the flight attendants may just have been in their way.
Sent 5: 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.
Sent 6: 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.
Sent 7: Lewin had served four years as an officer in the Israeli military.
Sent 8: He may have made an attempt to stop the hijackers in front of him, not realizing that another was sitting behind him.
Sent 9: 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.
Sent 10: They claimed they had a bomb.
Sent 11: 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.
Sent 12: 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.
Sent 13: 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.
Sent 14: 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."Sent 15: She then told of the stabbings of the two flight attendants.
Sent 16: 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.
Sent 17: Marquis soon realized this was an emergency and instructed the airline's dispatcher responsible for the flight to contact the cockpit.
Sent 18: At 8:23, the dispatcher tried unsuccessfully to contact the aircraft.

Example Input: Paragraph- Sent 1: She led the way into the cheerful schoolroom, where big girls and little girls were sitting about, amusing themselves in the quiet of a long Sunday afternoon.
Sent 2: Several of the younger children ran to her as she came in, and stood holding fast to the folds of her black habit, staring up at the strangers, while she explained the kind of instruction given, the system, and the order reigning in each department.
Sent 3: Finally, she persuaded a little girl, only six years old, to take her dusky face out of the long flowing veil of the nun, and show how quickly she could read a sentence that Sister Winifred wrote on the blackboard.
Sent 4: Then others were called on, and gave examples of their accomplishments in easy arithmetic and spelling.
Sent 5: The children must have been very much bored with themselves that stormy Sunday, for they entered into the examination with a quite unnatural zest.
Sent 6: Two of the elder girls recited, and some specimens of penmanship and composition were shown.

Sent 7: The FBI was struggling to build up its institutional capabilities to do more against terrorism, relying on a strategy called MAXCAP 05 that had been unveiled in the summer of 2000.
Sent 8: The FBI's assistant director for counterterrorism, Dale Watson, told us that he felt the new Justice Department leadership was not supportive of the strategy.
