Passage FourAt the 1893 Columbian Exposition, a World Fair held in Chicago, chocolate-making machinery made in Germany was displayed. It caught the eye of M.S. Hershey, who saw the potential for chocolate. He installed chocolate machinery in his factory in Lancaster, and produced his first chocolate bars in 1894.Other Americans began mixing in other materials to make up new candy bars throughout the end of the 1890's and the early 1900's. But it was World War Ⅰ that really brought attention to the candy bar.The U.S. Army Quartermaster Corps requested various American chocolate manufacturers to provide 20 to 40 pound blocks of chocolate to be shipped to quartermaster bases. The blocks were cut into smaller pieces and distributed to American soldiers in Europe. Eventually the task of making smaller pieces was turned back to the manufacturers. By the end of the war when the soldiers arrived home, the American candy bar business was assured. Why? Because the returning soldiers had grown fond of chocolate candy and wanted more of the same. As a result, from that time on and through the 1920's, candy bar manufacturers became established throughout the United States, and as many as 40,000 different candy bars appeared on the scene.The original candy bar industry had its start on the eastern coast in such cities as Philadelphia, Boston, and New York. The industry soon spread to the Midwest because shipping and raw materials such as sugar, corn syrup, and milk were easily available. Chicago became the seat of the candy bar industry and is even today an important base.Which event brought the booming of American candy bar business?

Passage FiveMark Twain is one of America's much-beloved authors, creating imaginative and humorous classics for children and adults alike, such as The Adventures of Tom Sawyer, The Prince and The Pauper, and Adventures of Huckleberry Finn. Twain passed away in 1910, leaving behind a treasure of great literature. But now, 100 years after his death, he'll have a brand-new book on the shelves: a three-volume autobiography.Twain hasn't been keeping busy in his tomb: it was his wish that publishers wait until 100 years after his death to publish his memoirs（自传）, which he spent the last decade of his life working on.The autobiography totals more than 5,000 pages, and likely won't be all sunshine and roses. It seems that Twain harbored some bitterness against former girlfriends and ex-friends. He also writes negatively about politicians of his day, such as Teddy Roosevelt. It's likely that he requested such a long lead time for the memoirs because he didn't want to hurt the feelings of anyone mentioned in this work.Although small sections of the memoirs have been previously published, the autobiography has never been available in full, and should provide great insights into the man behind the classic books. The first volume of the set will be available in November, and the trilogy is being published by the University of California, Berkeley."There are so many biographies of Twain, and many of them have used bits and pieces of the autobiography," editor Robert Hirst told The Independent. "But biographers pick and choose what bits to quote. By publishing Twain's book in full, we hope that people will be able to come to their own complete conclusions about what sort of a man he was.According to Paragraph 1, which of the following statements is TRUE of Mark Twain?
