[Q]: Question: What are earthwork mounds made of? Passage:Indigenous peoples inhabited Missouri for thousands of years before European exploration and settlement. Archaeological excavations along the rivers have shown continuous habitation for more than 7,000 years. Beginning before 1000 CE, there arose the complex Mississippian culture, whose people created regional political centers at present-day St. Louis and across the Mississippi River at Cahokia, near present-day Collinsville, Illinois. Their large cities included thousands of individual residences, but they are known for their surviving massive earthwork mounds, built for religious, political and social reasons, in platform, ridgetop and conical shapes. Cahokia was the center of a regional trading network that reached from the Great Lakes to the Gulf of Mexico. The civilization declined by 1400 CE, and most descendants left the area long before the arrival of Europeans. St. Louis was at one time known as Mound City by the European Americans, because of the numerous surviving prehistoric mounds, since lost to urban development. The Mississippian culture left mounds throughout the middle Mississippi and Ohio river valleys, extending into the southeast as well as the upper river.

[Q]: Question: Do more people live in Fauntleroy's birth place than the town where he died? Passage:Archibald Magill Fauntleroy (b. in Warrenton, Virginia, 8 July 1837; d. in Staunton, Virginia, 19 June 1886) was a physician. He graduated in medicine at the University of Pennsylvania in 1856, and in 1857 entered the United States Army as assistant surgeon; but, upon the start of the Civil War, he and his brother, a lieutenant in the navy, resigned at the same time with their father, Thomas T. Fauntleroy. He became a surgeon in the Confederate army, and was president of the board for the admission of surgeons, and chief officer on the medical staff of Gen. Joseph E. Johnston, and served with him until the battle of Seven Pines. He was then ordered to build and organize the hospitals at Danville, Virginia, and afterward had charge of the military hospital at Staunton, Virginia, until the war ended. He remained and practised at Staunton after the war, and was for several years superintendent of the lunatic asylum at that place. His contributions to medical literature include papers on potassium bromide, chloral hydrate, the use of chloroform in obstetrical practice, and a “Report upon Advance in Therapeutics,” which was printed in the Transactions of the Virginia Medical Society.

[Q]: Question: Did Capra's former Mets manager who selected him to the NL All-Star team have a different given name than the one he commonly was known by? Passage:Over his next three games, Capra went 2-0, with a 1.00 ERA. He allowed just three walks, while striking out fifteen, and began a Braves-record streak of 26 innings pitched without allowing an earned run. Over the month of June, Capra went 6-0 with a 1.05 ERA, three shutouts, and another complete game, to set a team record with nine consecutive wins, on his way to earning NL Player of the Month honors, and selection to the NL All-Star team by his former manager with the Mets, Yogi Berra. (He did not make an appearance in the game.) Capra cooled off during July and August (3-5, 4.43 ERA), but reverted to form in September, to end the season with a major league-best 2.28 ERA, 0.10 better than teammate, Phil Niekro (who finished second in the NL), and .21 better than American League (AL) leader, Catfish Hunter of the Oakland A’s. He also held opposing batters to an NL-leading .208 batting average against (BAA).
