[EX Q]: 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 prudentand 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>Contrast Tokugawa's attitude toward the British and Dutch traders and the Portuguese and Spanish missionaries.<sep>He was accepting of the British and Dutch, but not of the Portugese & Spanish

[EX Q]: Plants also detect the daily cycle of light and darkness. Do you know how plants respond to these changes? Some plants open their leaves during the day. It is during these hours the plant can collect sunlight. At night, the plant closes its leaves to prevent water loss. Many plants respond to the change in the length of the day. As days grow shorter, some plants respond by going dormant. Dormant is when a plant suspends its growth. It does this in order to survive. Shorter days signal the coming of winter. Winter in most areas means extreme cold. It is also very dry in the winter months. As winter approaches, some plants respond by their leaves changing color. After the change in color, they fall off. This dormancy period helps trees. It allows them to survive the cold and dry winter. Plants only want to grow when conditions are right. <sep>Why do some plants go dormant in winter?<sep>Because it is dying
[EX A]: No

[EX Q]: The little party in the cabin, so disastrously begun, finished, under the mellowing influence of wine and woman, in excellent feeling and with some hilarity. Mamie, in a plush Gainsborough hat and a gown of wine-coloured silk, sat, an apparent queen, among her rude surroundings and companions. The dusky litter of the cabin set off her radiant trimness: tarry Johnson was a foil to her fair beauty; she glowed in that poor place, fair as a star; until even I, who was not usually of her admirers, caught a spark of admiration; and even the captain, who was in no courtly humour, proposed that the scene should be commemorated by my pencil. It was the last act of the evening. Hurriedly as I went about my task, the half-hour had lengthened out to more than three before it was completed: Mamie in full value, the rest of the party figuring in outline only, and the artist himself introduced in a back view, which was pronounced a likeness. But it was to Mamie that I devoted the best of my attention; and it was with her I made my chief success. <sep>What was the last act of the evening?<sep>The speaker drawing the festivities
