Input: 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.
"What might cause a river to overflow its banks?" is "River valley"?

Input: Energy often changes from one form to another. For example, the drummer transfers motion to sound energy. When the moving drumstick strikes the drum head, the drum starts to vibrate. The motion of the vibrating drum head creates the sound you hear. Any form of energy can change into any other form. Frequently, one form of energy changes into two or more different forms. Have you ever sat in front of a campfire? What are two things you notice? The fire creates light. It is also warm by the fire, meaning it creates heat. The energy of the fire comes from the stored energy in the wood. The wood contains chemical energy. As it burns, the chemical energy is changed into light and heat. Not all chemical energy changes produce light and heat. Our cars use gasoline as a fuel. Gasoline contains chemical energy. When our cars burn gasoline in their engines, it is converted into motion and heat. When energy changes forms, energy is conserved.
"What do wood and gasoline have in common?" is "They contain chemical energy"?
Output: yes
Input: When 74-year-old Penny Sweat was evicted from the HUD-subsidized Glendale Senior Housing in Salt Lake City last month, she moved to a nonsubsidized apartment at five times her previous rent because she was unaware of her rights. It turns out the manager of the seniors complex, its attorneys and government overseers were unaware, too. Lee Kemp, a hearing-impaired World War II disabled vet, also was evicted, but he contacted Utah Legal Services and was told to stay put. Attorney Marty Blaustein then notified Utah Nonprofit Housing Corp., the building's owner, that Kemp's eviction was not legal and that he had a right to a hearing. That didn't stop Utah Nonprofit Housing's attorneys from then sending Kemp a summons to show cause why he had not moved out. Meanwhile, Sweat's granddaughter called Salt Lake City housing officials, federal housing officials, state officials and several agents of Utah Nonprofit Housing to find out about her grandmother's rights. Nobody knew. Blaustein then took Sweat's case along with Kemp's and demanded her ousting be rectified. Utah Nonprofit Housing President Marion Willey returned from an out-of-town trip and learned HUD procedures were not followed. The eviction was activated because of ongoing personality conflicts among seniors in the complex, he said, and the new building manager decided the problems were with Sweat and Kemp. Several tenants blame other neighbors as perpetrators of the rift, however. Willey said when his building manager called attorneys retained by the company, they erroneously told her she could go ahead and kick out the tenants. When she called HUD to make sure, the inquiry got bogged down in bureaucracy and nobody called her back. Willey says he has offered Sweat and Kemp apartments in another complex operated by his company at their old rates. He also is retaining new attorneys.
"Who called HUD to make sure she was allowed to kick out the tenants?" is "Building manager"?
Output:
yes
