Question: Question: How many regular NHL seasons had there been before the 1999-2000 hockey season? Passage:Before the 1999–2000 NHL season Torchetti was hired as an assistant coach for the Tampa Bay Lightning under Steve Ludzik. In 2002 Torchetti was hired as head coach of the San Antonio Rampage.

In 2004, he served 27 games as interim head coach, replacing Rick Dudley. He finished with a 10–12–4–1 record before being replaced by Jacques Martin.

Question: Question: Around what age was Ingmar Bergman when he rose to prominence? Passage:The famous and influential Swedish filmmaker, Ingmar Bergman, rose to prominence in the fifties. He began making films in the mid-forties, and in 1955, he made Smiles of a Summer Night, which brought him international attention. A year later, he made one of his most famous films, The Seventh Seal. In the 1960s, Bergman won the Academy Award for Best Foreign Language Film for two consecutive years, with The Virgin Spring (Jungfrukällan) in 1960 and Through a Glass Darkly (Såsom i en spegel) in 1961. He won the award again in 1983, for the early twentieth-century family drama Fanny and Alexander (Fanny och Alexander). Bergman has also been nominated for the Best Picture award once, with the 1973 Cries and Whispers (Viskningar och rop), the story of two sisters watching over their third sister's deathbed, both afraid she might die, but hoping she does. The film lost to The Sting, and oddly enough, it was not nominated in the Foreign Language Film category. It also gave Bergman the first of three nominations for Best Director. Ingmar Bergman also won four Golden Globe Awards for Best Foreign Language Film.

Question: Question: How long had Chiyoda Corporation been in business when the Flue-gas desulfurization equipment they helped Black & Veatch design was installed? Passage:During construction of Unit 4, a cooling tower was commissioned by Cincinnati Gas and Electric (CG&E) (a forerunner of Duke Energy) in order to meet pollution control mandates set by the State of Ohio. Its four smokestacks were upgraded with electrostatic precipitators to prevent fly ash from being released into the atmosphere. Stuart was the test site for the Low- Cell Burner (LNCB) designed by Babcock & Wilcox. The LNCB project utilized Unit 4 over a duration of 53 months from 1990–1994. The test confirmed that a LNCB can reduce nitrogen oxide () emissions by more than 50%, but the carbon monoxide (CO) emissions were inconclusive. Each unit at Stuart were retrofitted with selective catalytic reduction (SCR) systems between 2003–2004 by Black & Veatch. The SCRs were installed to comply with the Clean Air Act's 1990 amendments and Ohio's State Implementation Plan (SIP). Flue-gas desulfurization (FGD) equipment, designed by Black & Veatch with assistance from the Chiyoda Corporation was installed at J.M. Stuart in 2008. The FGD equipment reduced 97% of the plant's sulfur dioxide () emissions. In order to support the FGD process, a smokestack was constructed.
