question:
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.

question:
Question: How many people could Stamford Bridge seat the year York joined Aston Villa? Passage:York started his career with Handsworth Royal, Birchfield Rangers and the Royal Air Force, and also guested for Chelsea during World War I. In March 1915 he joined Aston Villa as an amateur, signing professional forms in August 1919. He scored one goal in 17 games in 1919–20, but did not feature in the 1920 FA Cup Final, which ended in a 1–0 victory over Huddersfield Town at Stamford Bridge. He appeared just 11 times in 1920–21, before going on to make 47 appearances in the 1921–22 campaign, as the "Villans" finished fifth in the First Division. He scored nine goals in 37 games in 1922–23 and five goals in 43 games in 1923–24. He also appeared at Wembley in the 1924 FA Cup Final, in a 2–0 defeat to Newcastle United. He scored seven goals in 34 matches in 1924–25, before hitting 20 goals in 44 appearances in 1925–26. He bagged 13 goals in 43 games in 1926–27, before being limited to just four goals in 30 appearances in 1927–28. He rediscovered his scoring form with 18 strikes in 48 matches in 1928–29, before hitting seven goals in 32 games in 1929–30. However he played just four times in the 1930–31 campaign, as Villa finished second in the league with an English record of 128 top-flight league goals scored.

question:
Question: How many years had WNOK been operating when WQXL switched to country music? Passage:The station became WQXL in 1962 after the station was sold to the Belk Broadcasting Company. The WOIC call sign resurfaced that same year on 1320 AM (now WISW). WQXL originally aired a Big Band format, which eventually gave way to a Top 40 format by the end of the decade. However it was handicapped with a daytime-only signal and was unsuccessful in competing against format rivals 1230 WNOK and 1400 WCOS, which each had full-time signals. Probably its most notable personality was Mackie "Cactus" Quave who had worked at 560 WIS (now WVOC) and had a successful kids TV show on NBC Network affiliate Channel 10 WIS-TV. WQXL switched to country music in the summer of 1966, but again was bested by rival 620 WCAY (now WGCV). In 1973, the station switched to religious programming and eventually adopted a Contemporary Christian format.
