[EX 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.

[EX Q]: Question: Did the American Hockey League have more teams than the Quebec Major Junior Hockey League the year Bergevin was drafted by the Blackhawks? Passage:Bergevin was drafted by the NHL's Chicago Blackhawks in the 1983 NHL Entry Draft, third round, 59th overall. After a junior career with the Chicoutimi Saguenéens of the Quebec Major Junior Hockey League (QMJHL), he made the Black Hawks in 1984 and played with Chicago for the next five seasons before being traded to the New York Islanders. His career with the Islanders was brief, and he spent much of that time with their American Hockey League (AHL) affiliate Springfield Indians, whom he helped lead to consecutive Calder Cup championships in 1990 and 1991. In the 1991 season he was traded to the Hartford Whalers and became a fan favorite for his skilled checking. The 1991–92 was his best season statistically, scoring 7 goals and 17 assists for 24 points.
