Problem: 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: "What is the flood plain area of land good for if it floods often?"

Answer: "Nile River"

Question:
Earth processes have not changed over time. The way things happen now is the same way things happened in the past. Mountains grow and mountains slowly wear away. The same process is at work the same as it was billions of years ago. As the environment changes, living creatures adapt. They change over time. Some organisms may not be able to adapt. They become extinct. Becoming extinct means they die out completely. Some geologists study the history of the Earth. They want to learn about Earths past. They use clues from rocks and fossils. They use these clues to make sense of events. The goal is to place things in the order they happened. They also want to know how long it took for those events to happen. After reading the above, is "Water" the correct answer to the question "Besides rocks, what else do geologists study to find clues to make sense of past events?"? OPTIONS:
- no
- yes

Answer:
no

Input: For thousands of years, people have found fossils. The fossils caused curiosity about Earths past. How did these organisms live? What type of world did they live in? Fossils can tell us a lot about Earths history. In ancient times, fossils inspired myths and stories. These stories included tales of monsters and other incredible creatures. What type of creature do you know that could inspire such stories? Of course, dinosaur fossils were once mistaken for dragons bones. Two thousand years ago, people discovered fossils in China. At the time, they were thought to be dragon bones. We know now that these were not bones, but fossils. So what is the difference?
"What were some fossils originally thought to be?" is "Incredible Creatues"?

OPTIONS:
- no
- yes
Output: yes

Input: Enter the Shoguns: Japan's austere, ruthless, but statesmanlike new ruler, Yoritomo Minamoto, set up his government in Kamakura (just south of modern Tokyo), well away from the "softening" influence of court life that had been the undoing of his predecessor, Kiyomori. First of the national rulers to take the title of sei-i tai-shogun ("barbarian-subduing great general"), Minamoto expanded and consolidated his power by confiscating lands from some of the defeated Taira and redistributing them to his samurai vassals. Minamoto died in 1199, and the feudal structure passed intact to the tutelage of his widow's family, the Hojo, who were content to play regent to a figurehead shogun, in much the same way as the Fujiwara had done with the emperor. The fiction of Japanese imperial power had become infinitely extendable. The emperor at Kyotostill seconded by a Fujiwara regent at courtlegitimized a Minamoto who was himself a military dictator controlled by a Hojo regent. In a country where form and substance were inextricably interrelated, two things counted in politics: symbolic authority and real power. Neither could exist without the other. A thwarted Mongol invasion in 1274 weakened the Kamakura regime. The fighting brought none of the usual spoils of war that provincial warlords and samurai had come to expect as payment. And the treasury was empty after earthquake, famine, and plague had crippled the economy. Buddhist monasteries were using their private armies to support imperial ambitions to bring power back to Kyoto. Worst of all, the Kamakura warriors, resenting the way the Kyoto court referred to them as "Eastern barbarians," sought refinement in a ruinous taste for luxury: extravagant feasts, rich costumes, and opulent homes. Kamakura was falling apart.

Does the response "By setting up set up a government in Kamakura" correctly answer the question "How did Minamoto expand his power?"?

OPTIONS:
- no
- yes

Output: no

Input: We waited for half an hour, watching the smoke curling over the house, and then, judging that the Indians had made off for fear of being ambushed, we crossed the clearing. It took but a glance to read the story. The women had been washing by the little brook before the cabin, with the children playing about them, when the Indians had come up and with a single volley killed them all except the child we had heard crying. They had swooped down upon their victims, torn the scalps from their heads, looted the house, and set fire to it. We dragged out the body of the woman which had been thrown within, in the hope that a spark of life might yet remain, but she was quite dead. Beneath the warrior Spiltdorph had shot we found the child. It was a boy of some six or seven years, and so covered with blood that it seemed it must be dead. But we stripped it and washed it in the brook, and found no wounds upon it except in the head, where it had been struck with a hatchet before its scalp had been stripped off. The cold water brought it back to life and it began to cry again, whereat Spiltdorph took off his coat and wrapped it tenderly about it.
"Who died in the attack?" is "Everyone"?

OPTIONS:
- no
- yes
Output:
no
