[EX Q]: Passage: About 460, Roman diplomat and bishop Sidonius Apollinaris sent a letter to Riothamus asking his help to quell unrest among the Brettones, British colonists living in Armorica; this letter still survives. In the year 470, Western Emperor Anthemius began a campaign against Euric, king of the Visigoths who were campaigning outside their territory in Gaul. Anthemius requested help from Riothamus, and Jordanes writes that he crossed the ocean into Gaul with 12,000 soldiers. The location of Riothamus' army was betrayed to the Visigoths by Arvandus, the jealous praetorian prefect of Gaul, and Euric defeated him in the Battle of Déols after Riothamus army was driven from Avaricum (Bourges) where he had been welcomed by the Bituriges before the fight. Riothamus was last seen retreating northward to Burgundy when Euric besieged Arvernum (Clermont-Ferrand) just south of the Bituriges territory.
 Link Information: A letter of Sidonius's addressed to Riothamus, "King of the Brittones" (c. 470) is of particular interest, since it provides evidence that a king or military leader with ties to Britain lived around the time frame of King Arthur. The best edition is that in the Monumenta Germaniae Historica (Berlin, 1887), Answer: Berlin
[EX A]: Where is the letter that Sidonius Apollinaris sent to Riothamus currently being held?

[EX Q]: Passage: The highway begins at Highway 28 in western Scott County within the Ouachita Mountains. Highway 28 runs southeast to Waldron, where it has a junction with US Highway 71 (US 71) on the city's west side. After this intersection, Highway 80 continues due east as a section line road and major east–west route in the city. An intersection with US Highway 71 Business (US 71B) just south of downtown Waldron gives access to the primary commercial areas of Waldron. Continuing east, the highway serves as the western terminus for Highway 248 just south of the Poteau River near the eastern city limits of Waldron. Just east of this junction, Highway 80 passes the Poteau Work Center owned and operated by the United States Forest Service. East of Waldron, Highway 80 enters the Ouachita National Forest, a dense pine and cypress forest. The route winds through the forest, serving as the eastern terminus of Highway 250 before entering Yell County.
 Link Information: Waldron is a city in Scott County, Arkansas, United States. Its population was 3,618 Answer: 3,618 
[EX A]: What is the current population of the town where Highway 28 has a junction with US Highway 71?

[EX Q]: Passage: The source of the river is Lake Hendricks on the boundary of Lincoln County, Minnesota, and Brookings County, South Dakota. It issues from the lake in Hendricks, Minnesota, and flows northeastwardly through northwestern Lincoln County as an intermittent stream on the Coteau des Prairies, a morainic plateau dividing the Mississippi and Missouri River watersheds, into western Yellow Medicine County, where it flows off the Coteau, dropping 250 feet (76 m) in eight miles (13 km). Continuing northeastwardly through flat till plains with occasional willows and cottonwoods along its banks, the river flows into eastern Lac qui Parle County, passing to the east of Dawson. It flows into the Minnesota River just below Lac qui Parle Lake in Lac qui Parle State Park, approximately ten miles (15 km) northwest of Montevideo, after flowing through a wooded valley in which it drops 210 feet (64 m) in 18 miles (29 km). Lac qui Parle Lake was formed by a delta at the mouth of the Lac qui Parle River, and is maintained by a dam.
 Link Information: The population was 713 at the 2010 census Answer:  713
[EX A]:
What is the population of the city where the body of water that feeds the Lac qui Parle River is located?
