[EX Q]: 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.
 Link Information:  earthworks are artificial changes in land level, typically made from piles of artificially placed or sculpted rocks and soil. Question: What are earthwork mounds made of?
[EX A]: Answer:  sculpted rocks and soil.

[EX Q]: Passage: He made his "Seals" debut in a 1–1 draw with Cambridge United in August 1972, and went on to bag 41 league goals in 199 appearances in one of the most successful periods in the club's history. A 15th-place finish in the Fourth Division in 1972–73 was followed by a seventh-place finish in 1973–74. Ken Roberts's side achieved promotion in 1974–75 by securing the fourth automatic promotion place with only a slender higher goal average than fifth place Lincoln City. More remarkably, Chester reached the semi-finals of the League Cup, beating Leeds United and Newcastle United along the way. Owen scored in the 2–2 first-leg draw with Aston Villa at Sealand Road, and played in the return game as Chester narrowly lost 3–2 at Villa Park to deny Owen an appearance at Wembley Stadium. Owen finished as the club's top league scorer during the campaign, with 14 goals to his name. He managed double-figures again in 1975–76, as Chester retained their Third Division status. Another mid-table finish was achieved in 1976–77 under player-manager Alan Oakes, and Owen also featured in the FA Cup Fifth Round defeat to Wolverhampton Wanderers at Molineux.
