Problem: When land is cleared, habitats are lost. It may be cleared for agriculture. It may also be used for building new homes or businesses. Within the past 100 years, the amount of land used for agriculture has almost doubled. Land used for grazing cattle has more than doubled. Many wetlands have also been lost to agriculture. The U.S. has lost almost all the natural tall-grass prairies. Thee areas of tall thick grass have virtually disappeared. These areas of land had thick fertile soil. Their grasses had very deep root systems. These deep and thick roots reduced the amount of soil erosion. They also were home to many plants and animals. Prairies were wonderful places. They were home to colorful flowers, prairie dogs, and herds of bison.

Question: "Why do we clear land?"

Answer: "Space for prairie dogs"
Answer: no

Problem: 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.

Question: "How much longer was the United 93 takeover than their previous attemps?"

Answer: "16 minutes"
Answer: yes

Problem: Nathan read the package of words in silence, his only motions the steady progress of his eyes and occasional replacement of pages. Allan sat nervously across from him in a chair Nathan had probably upholstered himself, a patchwork design of fabric containing easily more stuffing than any other furniture item of the period. At long last, Nathan reached the end and set down his reading on the table between them. Allan leaned forward unconsciously. "It's the best story you've ever written." Allan exhaled and leaned back into the chair, his face relaxing in imitation of his thoughts. "So," he asked, "you don't think it's a waste of ink and paper, a futile expedition into morbidity or literary debauchery?" "Heavens, no," said Nathan, aghast. "This is one of the strongest works I've read in ages. It speaks to the deepest storyteller's instinct within us all, yet is entirely original. My dear friend, you have done it. Oh, they may rail against you at first; they may decry you as a heathen or a literary savage; but while those in power say such things, others will read your tales and see their true worth. Believe me when I say that you will be read a century from now." Allan, though dubious as to that possibility, felt some temptation from the compliment; mainly, it granted him the encouragement he still needed. Nathan promised to show the story to a printer he knew and Allan left it with him, then walked home under the spreading maples with a smile lingering on his face. He felt now that perhaps Nathan was right; although the man was somewhat peculiar, he had both an unimpeachable honesty and a certain propensity for insight. Certainly, it was undeniable that the stories had an originality to them. His mind's strangest fruit had ripened at last, and he found the taste less bitter than expected. These thoughts and others like them filled his head as he walked the long road home. It was evening, and the sky burned orange in the west when he neared home at last.

Question: "Who wrote the story?"

Answer: "Allan"
Answer:
yes
