PROBLEM: Passage: As previously arranged by his father, Temüjin married Börte of the Onggirat tribe when he was around 16 in order to cement alliances between their respective tribes. Soon after Börte's marriage to Temüjin, she was kidnapped by the Merkits and reportedly given away as a wife. Temüjin rescued her with the help of his friend and future rival, Jamukha, and his protector, Toghrul Khan of the Keraite tribe. She gave birth to a son, Jochi (1185–1226), nine months later, clouding the issue of his parentage. Despite speculation over Jochi, Börte would be Temüjin's only empress, though he did follow tradition by taking several morganatic wives. Question: Who helped Temüjin rescue his wife from the Merkits?

SOLUTION: Jamukha, and his protector, Toghrul Khan

PROBLEM: Passage: Southern California consists of a heavily developed urban environment, home to some of the largest urban areas in the state, along with vast areas that have been left undeveloped. It is the third most populated megalopolis in the United States, after the Great Lakes Megalopolis and the Northeastern megalopolis. Much of southern California is famous for its large, spread-out, suburban communities and use of automobiles and highways. The dominant areas are Los Angeles, Orange County, San Diego, and Riverside-San Bernardino, each of which is the center of its respective metropolitan area, composed of numerous smaller cities and communities. The urban area is also host to an international metropolitan region in the form of San Diego–Tijuana, created by the urban area spilling over into Baja California. Question: What kind of region can be found inside the urban area of southern California?

SOLUTION: international metropolitan

PROBLEM: Passage: The first recorded settlement in what is now Newcastle was Pons Aelius, a Roman fort and bridge across the River Tyne. It was given the family name of the Roman Emperor Hadrian, who founded it in the 2nd century AD. This rare honour suggests that Hadrian may have visited the site and instituted the bridge on his tour of Britain. The population of Pons Aelius at this period was estimated at 2,000. Fragments of Hadrian's Wall are still visible in parts of Newcastle, particularly along the West Road. The course of the 'Roman Wall' can be traced eastwards to the Segedunum Roman fort in Wallsend—the 'wall's end'—and to the supply fort Arbeia in South Shields. The extent of Hadrian's Wall was 73 miles (117 km), spanning the width of Britain; the Wall incorporated the Vallum, a large rearward ditch with parallel mounds, and was constructed primarily for defence, to prevent unwanted immigration and the incursion of Pictish tribes from the north, not as a fighting line for a major invasion. Question: What river was there originally a bridge across in Roman times?

SOLUTION:
the River Tyne
