Input: 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. 

Does the response "Years" correctly answer the question "What types of animals did prairies contain?"?

In the period before World War II, the New York Times published a vignette in their "The Talk of the Town" feature saying that Einstein was so well known in America that he would be stopped on the street by people wanting him to explain "that theory". He finally figured out a way to handle the incessant inquiries. He told his inquirers "Pardon me, sorry! Always I am mistaken for Professor Einstein." Einstein has been the subject of or inspiration for many novels, films, plays, and works of music. He is a favorite model for depictions of mad scientists and absent-minded professors; his expressive face and distinctive hairstyle have been widely copied and exaggerated. Time magazine's Frederic Golden wrote that Einstein was "a cartoonist's dream come true". 

Question: "Why did Einstein pretend to be mistaken for Professor Einstein?"

OPTIONS:
- no
- yes

Problem: The CIA's senior management saw problems with the armed Predator as well, problems that Clarke and even Black and Allen were inclined to minimize. One (which also applied to reconnaissance flights) was money. A Predator cost about $3 million. If the CIA flew Predators for its own reconnaissance or covert action purposes, it might be able to borrow them from the Air Force, but it was not clear that the Air Force would bear the cost if a vehicle went down. Deputy Secretary of Defense Wolfowitz took the position that the CIA should have to pay for it; the CIA disagreed. Second, Tenet in particular questioned whether he, as Director of Central Intelligence, should operate an armed Predator." This was new ground,"he told us. Tenet ticked off key questions: What is the chain of command? Who takes the shot? Are America's leaders comfortable with the CIA doing this, going outside of normal military command and control? Charlie Allen told us that when these questions were discussed at the CIA, he and the Agency's executive director, A. B." Buzzy" Krongard, had said that either one of them would be happy to pull the trigger, but Tenet was appalled, telling them that they had no authority to do it, nor did he. Third, the Hellfire warhead carried by the Predator needed work. It had been built to hit tanks, not people. It needed to be designed to explode in a different way, and even then had to be targeted with extreme precision. In the configuration planned by the Air Force through mid-2001, the Predator's missile would not be able to hit a moving vehicle. White House officials had seen the Predator video of the "man in white." On July 11, Hadley tried to hurry along preparation of the armed system. He directed McLaughlin, Wolfowitz, and Joint Chiefs Vice Chairman Richard Myers to deploy Predators capable of being armed no later than September 1. 

Question: "Why did the CIA want the Airforce to pay if a Predator was downed?"

Answer: "Predator"

A flood occurs when a river overflows its banks. This might happen because of heavy rains. Floodplains In very flat regions, flood water may spread out on the surface of the land. It then slows down and drops its sediment. If a river floods often, a floodplain develops. A floodplain is an area where a thick layer of rich soil is left behind as the floodwater recedes. Thats why floodplains are usually good places for growing plants. They are very flat areas and they have very rich soils. The Nile River valley is a great example of a floodplain. Each year, the Nile River rises over its banks. This floodwater carries a lot of sediment. This sediment has been eroded off areas of land from upstream. This sediment is dropped as the water slows down after spreading across the land. What is left behind is a very rich soil. Thats why crops can be raised in the middle of a sandy desert. Natural Levees A flooding river often forms natural levees along its banks. A levee is a raised strip of sediments deposited close to the waters edge. 

Question: "Where does the sediment in a flooding river come from, and where does it eventually come to rest?"

Response: "Natural levees"
