Ex 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. <sep>What makes the floodplains good for growing plants?<sep>Very rich soil

Tokugawa Takes All: When Hideyoshi died in 1598, he hoped to have his five-year-old son continue his "dynasty," initially under the tutelage of five regents. But one of the regents was Ieyasu Tokugawa, who had been biding his time at Edo for 12 years, nurturing dynastic ambitions of his own. Of the cunning, ruthless triumvirate that came out on top at the end of the country's century of civil war, Tokugawa was without doubt the most patient, the most prudent — and most treacherous. He moved quickly to eliminate his strongest rivals, crushing them in 1600 at the great Battle of Sekigahara (near modern Nagoya). During its subsequent two and a half centuries of rule from the new capital established at Edo, the Tokugawa organized a tightly controlled coalition of some 260 daimyo in strategic strongholds throughout the country. The allegiance of this highly privileged and prestigious group was ensured by cementing their ethical principles in the code of bushido, "The way of the warrior": loyalty to one's master, defense of one's status and honor, and fulfillment of all obligations. Loyalty was further enforced by holding the vassals' wives and children hostage in Edo. All roads into Edo, the most famous being the Tokaido Highway, had checkpoints for guns coming in and for wives going out. One of the most effective ways of keeping a tight rein on the country was to cut it off from the outside world, to keep Japan Japanese. At first, Ieyasu Tokugawa was eager to promote foreign trade. He wanted silk and encouraged the Dutch and British as good, nonproselytizing Protestants just interested in trade. But he didn't like the Portuguese and Spanish Catholic missionaries, who he felt were undermining traditional Japanese values. He banned their activities in 1612 and two years later ordered the expulsion of all missionaries and unrepentant Japanese converts. Executions and torture followed. Converts were forced to renounce their faith by trampling crucifixes and effigies of Jesus and Mary. The Catholic Church has counted 3,125 martyrs in Japan from 1597 (beginning under Hideyoshi) to 1660. In 1635 the Japanese were forbidden, on pain of death, to attempt to travel abroad, and Japanese citizens already overseas were prevented from returning, in case they brought back subversive Christian doctrines. Western books were banned, as were Chinese books that mentioned Christianity. <sep>What was one cruel way in which the Bushido Code was enforced?<sep>A vassal's wife and children were held hostage in Edo to force loyalty

Yes

(CNN) -- A federal court jury in Florida convicted seven people of participating in a global child pornography trafficking enterprise, according to the Department of Justice. Jurors convicted the seven Wednesday of multiple counts of child exploitation, pornography and obstruction of justice. Members of the organization used Internet news groups to swap and share "illegal images and videos depicting prepubescent children, including toddlers, engaged in various sexual and sadistic acts," prosecutors said. An indictment filed in the case detailed interactions between group members as they swapped and commented on images. "My thanks to you and all the others that together make this the greatest group of pedos to ever gather in one place," Freeman wrote in response to one posting, according to the indictment. And a posting from Castleman, cited in the indictment, read, "Thanks to all for the wonderful material that has been posted." An Australian constable who infiltrated the group in August 2006 was among 50 witnesses testifying at trial. He told the jury that the group traded more than 400,000 images and videos of child sexual abuse before being dismantled by law enforcement, according to the Justice Department statement. Each defendant faces a sentence of 20 years to life in prison, fines and the possibility of supervised release for the rest of their lives, authorities said. The seven will be sentenced April 14. During the six-day trial, evidence showed the seven participated in what prosecutors called a "well-organized criminal enterprise whose purpose was to proliferate child sex abuse images to its membership during a two-year period." "This was a wide-scale, high-volume, international trafficking enterprise that used sophisticated computer encryption technology and file-sharing techniques," Matthew Friedrich, acting assistant attorney general, said in the statement. The seven defendants were James Freeman of Santa Rosa Beach, Florida; Gary Lakey of Anderson, Indiana; Marvin Lambert of Indianapolis, Indiana; Neville McGarity of Medina, Texas; Warren Mumpower of Spokane, Washington; Daniel Castleman of Lubbock, Texas; and Ronald White of Burlington, North Carolina, according to the Department of Justice. <sep>Who told the jury that the group traded more than 400,000 images and videos of child sexual abuse?<sep>The seven defendents
