[EX Q]: Question: How long had St Mary's Church been standing the year Hans Olufsson died? Passage:The Paus family (earlier spellings include Pauss and de Paus) () is a Norwegian family that first appeared as members of the elite of 16th-century Oslo. Two brothers from Oslo who both became priests, Hans (1587–1648) and Peder Povelsson Paus (1590–1653), have long been known as the family's earliest certain ancestors. In his book Slekten Paus ("The Paus family"), genealogist S.H. Finne-Grønn traced the family two further generations back, to Hans Olufsson (died 1570), a member of the royal clergy in Norway before and after the Reformation, who served as a canon at the royal chapel in Oslo, St Mary's Church, the seat of government of Norway at the time, and who belonged to the high nobility by virtue of his high ecclesiastical and governmental office. The name Paus is known in Oslo since the 14th century, notably as the name of the Lawspeaker of Oslo Nikolas Paus (mentioned 1329–1347) and as the name of one of medieval Oslo's "city farms" (mentioned 1324–1482) that was probably named after the lawspeaker or his family; while a relation between the older and the younger family of the name in Oslo is plausible, it has not been established. Regardless, the modern Paus family is likely the only surviving family to hail from the medieval city of Oslo which burned down in 1624 without being rebuilt, making it the family with the longest documented history in the Norwegian capital.

[EX Q]: Question: Which of the three reservoirs produced by the damming of the Hackensack River was built first? Passage:The damming of the Hackensack River and a tributary, the Pascack Brook, produced three reservoirs in the county, Woodcliff Lake Reservoir (which impounds one billion gallons of water), Lake Tappan (3.5 billion gallons), and Oradell Reservoir, which allows United Water to provide drinking water to 750,000 residents of northern New Jersey, mostly in Bergen and Hudson counties. The Hackensack River drains the eastern portion of the county through the New Jersey Meadowlands, a wetlands area in the southern portion of the county. The central portion is drained by the Saddle River and the western portion is drained by the Ramapo River. Both of these are tributaries of the Passaic River, which forms a section of the southwestern border of the county.
