Question: Who was the other finalist in the 1930 Allan Cup other than the team Roche was on? Passage:Roche was born in Prescott, Ontario, but moved to Montreal where he played junior hockey for the Montreal Victorias and other teams. He moved up to senior hockey for the Montreal Hockey Club and played for their Allan Cup-winning squad of 1930. He signed with the Maroons of the NHL, playing for the Maroons and the Windsor Bulldogs until 1933. He was released by the Maroons and signed with the Bruins in January 1933 only to be traded to the Senators one month later. In his one full season with the Senators in 1933–34 he showed a scoring touch, scoring 13 goals and 16 assists in 45 games. The next season, the Senators relocated to St. Louis to become the Eagles. Roche was traded twice in 1934–35; from St. Louis to Buffalo, then to the Red Wings. That marked his last season in the NHL, as he subsequently played for various minor-league pro teams until 1942.

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: What role did the actor portraying the tenth doctor follow his run on the show with? Passage:The regeneration of the Ninth Doctor into the Tenth at the end of "The Parting of the Ways" (2005) used computer effects to morph Christopher Eccleston into David Tennant. In the episode of Doctor Who Confidential accompanying the episode "Utopia" (2007), where the same effect is used for the Master's regeneration, it is stated that the production team decided that this would be a common effect for all future Time Lord regenerations, rather than each regeneration being designed uniquely at the whim of the individual director. This style of transition is seen again in "The Stolen Earth"/"Journey's End" (2008) both when the Doctor undergoes an aborted regeneration, and when his hand spawns a clone in the second part; in The End of Time (2010) during which Matt Smith took over the role as the Eleventh Doctor; in "The Impossible Astronaut" when the Doctor is shot twice and seemingly killed; in "Day of the Moon" when a young girl regenerates; and in "Let's Kill Hitler" when Mels (Nina Toussaint-White) is shot and regenerates into River Song (Alex Kingston). "The Night of the Doctor" and "The Day of the Doctor" subsequently use the effect to show the Eighth Doctor and War Doctor's regenerations respectively. The Eighth Doctor's regeneration into the War Doctor uses steady beams of light as opposed to the flame effect used for other revived series regenerations. In the Series 10 episode "The Lie of the Land", the Twelfth Doctor fakes a regeneration as part of a plan to test if Bill still has free will. The effect used is consistent with the one used in the modern series, with the Doctor's hands glowing and emitting regeneration energy before he enters full regeneration. However, as the regeneration was not real, it did not use up a regeneration and the Doctor did not change bodies.
