Q: Passage: He was a founder of the St. Louis Art Museum and the State Historical Society of Missouri, president of the St. Louis Public Library, and a director of the St. Louis World's Fair (Louisiana Purchase Exposition) of 1904, in which he was host of the Universal Congress of Jurists and Lawyers. He was a bibliophile and he collected rare first editions of Charles Dickens, Robert Burns and others, and artworks of Aubrey Beardsley, George Cruikshank and Thomas Rowlandson. He and industrialist William K. Bixby started the Burns Society; he was twice president of the University Club of St. Louis. He had a remarkable (possibly eidetic) memory—when writer Henry James visited his house, Lehmann could recite whole works that James himself had written but forgotten. For most his life Lehmann was in demand as a public speaker, which he thoroughly enjoyed. His published works included: John Marshall (1901); The Lawyer in American History (1906); Abraham Lincoln (1908); Conservatism in Legal Procedure (1909); Prohibition (1910); and The Law and the Newspaper (1917).

Q: Passage: The town was built on the mouth of a small tributary of the Severn Estuary near the mouth of the River Avon. The old pill or jetty provided protection for craft against the Bristol Channel's large tidal range, and iron rings can be seen in the high street at which fishing boats used to moor. Its position meant Portishead was used to guard the "King Road", as the waters around the headland are called. In 1497 it was the departure point for John Cabot on the Matthew. A fort was built on Battery Point, and was used during the English Civil War when the town supported the Royalists, but surrendered to Fairfax in 1645. Guns were also placed at Battery Point during World War II. The King Road was the site of a naval action in 1758 when HMS Antelope captured HMS Belliqueux, one of a French squadron returning from Quebec.

Q: Passage: The Lookout Mountain Incline Railway is a inclined plane funicular railway leading to the top of Lookout Mountain from the historic St. Elmo neighborhood of Chattanooga, Tennessee. Passengers are transported from St. Elmo's Station at the base, to Point Park at the mountain summit, which overlooks the city and the Tennessee River. It is just a short drive to three of Chattanooga's main tourist attractions, Ruby Falls, Cavern Castle, and Rock City. The railway is approximately in length (single-track except for a short two-track passing loop at the midway point, allowing operation of two cars at one time). It has a maximum grade of 72.7%, making it one of the world's steepest passenger railways. It obtained Historic Mechanical Engineering Landmark status in 1991. The cable system for the cars was made by the Otis Elevator Company.
