Question: Question: Who founded the record label that signed the group in 1956? Passage:The group was signed to Mercury in 1956, and were also spotted by film producer Sam Katzman. He offered them a part in Rock Around the Clock, the first rock and roll movie, starring Bill Haley. The first single for their new label was shared with Jerry Wallace, who later hit with "How The Time Flies" on Challenge. This record, on the Mercury subsidiary Wing Records was "I Said It And I'm Glad" b/w Jerry Wallace, "Eyes Of Fire Lips Of Wine", which was released February 27, 1956. Their second single was released on the same date. The A-side "Ding Dong", was written by Bell and his friend Pep Lattanzi in 1953. Later known as "Giddy Up a Ding Dong", it was not a hit in the United States, but it was popular in Australia, France, and the UK, where it climbed to number four in the UK Singles Chart. The publicity for the single said, "If these sides don't move you, see a doctor you're dead." The lyrics to the song are about a horse ride, with a definite western flavor, with the music having a loping, horse like cadence. The group also appeared in the 1956 film, Rumble on the Docks. In 1957, they became one of the first American rock and roll acts to tour the UK in 1956 when they supported Tommy Steele.

Answer: The group was signed to Mercury in 1956, and were also spotted by film producer Sam Katzman

Question: Question: How long had the Canadian Pacific Railway been in operation for the year the Electro-Motive Diesel entered full production? Passage:In 1996, Electro-Motive Diesel entered full production on their , 16-cylinder H-engine, and all SD90MACs made from then on used that for its prime mover. Locomotives fitted with this engine are sometimes referred to as SD90MAC-H locomotives. Later versions of the SD90MAC-H feature a Phase II cab, with a new nose which offers higher visibility from the cab than the old nose. The SD90MAC-H did not prove popular with railroads and less than 70 were built, including Electro-Motive Diesel demonstrator units. Since the SD90MAC-H had such a large prime mover, it didn't offer the same operational flexibility as smaller units, limiting its possible customer base to only the largest railroads. Also, since the H-engine was a new design it hadn't reached the same level of reliability as EMD's previous engine. The low reliability on such a large engine was an especially bad combination since the loss of one engine in a train meant the loss of a larger percentage of pulling power than had a smaller engine failed. In the end the SD90MAC-H was only delivered to two railroads, the Union Pacific Railroad and the Canadian Pacific Railway. The Canadian Pacific locomotives were part of an earlier order for 710-engine equipped SD90MAC locomotives that was still in production when Electro-Motive Diesel switched over to the H-engine.

Answer: In 1996, Electro-Motive Diesel entered full production on their , 16-cylinder H-engine, and all SD90MACs made from then on used that for its prime mover

Question: Question: What was the vocal range of the singer who performed in Samson and Delilah as Delilah at the Metropolitan Opera during its 1915/1916 season? Passage:The Metropolitan Opera revived the opera in its 1915/1916 season with Margaret Matzenauer as Delilah, Enrico Caruso as Samson, and Pasquale Amato as the High Priest. Since then the company has staged productions of the opera at least once every decade giving more than 200 performances of the work. Placido Domingo performed as Samson in the 1981 San Francisco Opera production co-starring Shirley Verrett, under Julius Rudel and at the Metropolitan Opera's 1998 production with Olga Borodina. More recent productions of the opera by the Metropolitan have been in 2006, with Marina Domashenko and Olga Borodina alternating as Delilah, and in 2018 with Elina Garanca and Roberto Alagna. The Lyric Opera of Chicago gave their first performance of the opera in November 1962 with Rita Gorr as Delilah and as Samson. The company has revived the work numerous times since then, most recently in their 2003/2004 season with Olga Borodina as Dalila and Jose Cura as Samson. Likewise, the San Francisco Opera has staged the opera 10 times during its history giving its first performance in 1925, with Marguerite d'Alvarez and Fernand Ansseau in the principal roles, and its most recent performance in 2008, with Borodina and Clifton Forbis.

The Metropolitan Opera revived the opera in its 1915/1916 season with Margaret Matzenauer as Delilah, Enrico Caruso as Samson, and Pasquale Amato as the High Priest
