[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.

[Q]: Question: How many of the judges of the season of the show Boyd won were also judges in that show's first season? Passage:In the first issue of Billboard of the year, Craig Wayne Boyd entered the Hot Country Songs chart at number one with "My Baby's Got a Smile on Her Face". Boyd, winner of season 7 of NBC's reality TV singing competition The Voice, was only the second artist in the chart's 57-year history to enter at number one. After holding the top spot for a single week, however, the song achieved the unusual feat of dropping off the chart entirely the following week. In addition to Boyd, one other artist was a first-time chart-topper on Hot Country Songs. Following a critically acclaimed performance at the 49th Country Music Association (CMA) Awards, Chris Stapleton's version of "Tennessee Whiskey", which had spent a single week at number 46 six months earlier, re-entered at number one, despite never having been officially released as a single or serviced to radio. Nine acts gained their first career country number ones by topping the airplay listing. Ashley Monroe made her first appearance at number one under her own name when she featured on Blake Shelton's hit "Lonely Tonight", although she had previously reached the top spot as part of the group Pistol Annies, who had been featured on another of Shelton's songs two years earlier. Between May and August, Tyler Farr, Kelsea Ballerini, Canaan Smith, Michael Ray, and the band A Thousand Horses were all first-time chart-toppers, as was Grace Potter, who was featured on veteran country star Kenny Chesney's song "Wild Child". Later in the year, the band Old Dominion and the duo Dan + Shay made their first appearances at number one.

Already in January 1986 her international career started and she debuted as Liù at the Royal Opera House, Covent Garden, and thereafter sung at the most prestigious opera houses of Europa and America.
