Question: Did Sætren study at multiple institutions within the same country between 1862 and 1865? Passage:Sætren studied at Lillehammer Latin- og Realskole, at Qvams skole in Christiania and at the Swiss Federal Institute of Technology Zurich from 1862 to 1865. In 1866 he started working as a draftsman for Kanalvæsenet, the body for exploitation of Norwegian water resources, and held various positions at Kanalvæsenet over a period of 41 years. He ended his career as manager for the Bandak-Norsjø Canal from 1891 to 1907. The boat locks of the Bandak-Norsjø Canal could lift boats with a length of up to 100 feet. The canal became an important water transport system, and also a tourist destination. Sætren was a counsellor for industrialist Sam Eyde, the founder and first mangager of Norsk Hydro, who acquired rights for exploiting waterfalls for hydroelectric power. Sætren published maps and overviews of water resources in Norway, such as his map  from 1904. He was the first editor of the magazine Norsk Teknisk Tidsskrift, which he edited from 1883 to 1886.

Question: How many wins did the coach Sonetti replaced for Brescia in 2008 have? Passage:More recently, Sonetti joined Cagliari on November 2005, replacing Davide Ballardini, becoming the fourth coach appointed by the Sardinian team in a couple of months. He succeeded in maintaining his job until the end of the tournament, and in leading the rossoblù to maintain a place in the next Serie A; he left Cagliari at the end of the season. On 14 November 2006, Sonetti was appointed to replace Attilio Tesser at the helm of then last-placed relegation-battling Serie A Ascoli. He did not manage to save his side from falling to Serie B, and ended his experience in Ascoli at the end of the season with a second-last place. On November 2007 he returned at Cagliari for his third time, as he was appointed to replace Marco Giampaolo at the helm of the Sardinians. He resigned from his post on 19 December, but was confirmed by the club the next day after Marco Giampaolo rejected to return at the helm of the club. However, Sonetti was sacked only a few days later, after a 5–1 loss to Fiorentina, leaving the team last-placed in the league table, being replaced by Davide Ballardini. From 25 September 2008, he has been called back to Brescia replacing Serse Cosmi. On 19 May 2009 he was sacked himself, following a 2–1 loss to promotion rivals Grosseto that left Brescia in fourth placed, but with only a two-point lead to 7th-placed Triestina.
