[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: Salvatore di Pietro was born in Palermo, Italy, on 15 June 1830. He entered the Society of Jesus (Jesuits) in October 1845 and was ordained a priest on 2 June 1859. He arrived in British Honduras (now known as "Belize") on 22 March 1869. On May 12 he suffered an attack of yellow fever. His superiors transferred him to Guatemala, where he preached missions to the Garifuna. He was appointed head of the missions in northern Guatemala, but along with 80 other Jesuits fled the country in September 1871 when the Liberals gained control and persecuted the Catholic Church. In 1872 president Jose Maria Medina invited him to Spanish Honduras to found a college in the capital Comayagua. He began by preaching missions in Omoa and San Pedro Sula. However, the Liberals took control of Spanish Honduras also and he returned to Belize.

[EX Q]: Passage: After the Second World War the Battery was re-formed in 1955 as 20 Medium Battery as part of 21 Med Regt based at Redford Barracks, Edinburgh but deployed in the Internal Security role to Cyprus in 1956 where the Regt lost several men to the EOKA terrorists. Re-numbered again and re-rolled (a change of equipment and role) as an Amphibious Operations (AO) Battery. They were posted to Hong Kong and renamed 20 Commando (AO) Battery as part of 29 Commando Regiment. Due to the fact that only 20 and 148 Commando (AO) Battery fulfilled the AO roll there was a lot of movement between the batteries most men serving in both. The battery had absorbed 3 (AO) Troop on their move to Hong Kong and was involved in a number of operations including the Korean War and a little known operation in the Caribbean during the Cuban missile crisis. The Battery was involved in clearing Russian, American and Cuban personnel off remote Caribbean islands in the region and arrested 60 men who later turned out to be CIA operatives, causing a minor political incident. The Battery was placed into suspended animation in 1969 following the downsizing of the British Army and the reduction to one Commando Artillery Regiment, having lost out to 148 Commando (AO) Battery. Many of 20 Commando (AO) Battery's personnel ended up in 148 Battery and so did much of the battery property.
 Link Information: none Question: In which country did 20 Battery Royal Artillery go to war?
[EX A]:
Answer: none
