Question: Klindworth took up the position of professor of pianoforte at a conservatory in what country? Passage 1:In 1854 Klindworth went to London, where he remained for fourteen years, studying, teaching and occasionally appearing in public. From London Klindworth went to Moscow in 1868, following Nikolai Rubinstein's invitation to take up the position of professor of pianoforte at the Moscow Conservatory, where he first met Pyotr Ilyich Tchaikovsky as professor of harmony. While in Russia he completed his pianoforte arrangements for Wagner's Der Ring des Nibelungen, which he had commenced during Wagner's visit to England in 1855, Beethoven's sonatas and also his critical edition of Frederic Chopin's works. He then became conductor of the Berlin Philharmonic in 1882, in association with Joseph Joachim and Franz Wullner, being also the conductor of the Berlin Wagner Society. At this time, he established the Klindworths Musikschule, which later became the Klindworth-Scharwenka Conservatory.
Passage 2:Kevin Francis (born June 5, 1993) is a professional Canadian football linebacker for the Ottawa Redblacks of the Canadian Football League (CFL). After going undrafted in the 2016 NFL draft, Francis declared eligible for the 2016 CFL Supplemental Draft after informing the league that he was born in Toronto, Ontario. He was drafted by the Roughriders on May 26, 2016, who forfeited a third round selection in the 2017 CFL Draft to acquire his rights. Upon entering 2016 training camp, Francis switched to the defensive side of the ball after playing as a tight end during his college football career with the North Carolina A&T Aggies. He made his CFL debut on June 30, 2016 against the Toronto Argonauts, registering his first defensive tackle. Francis finished his rookie season leading the team in special team tackles, also being ranked 7 on the CFL rising sophomore list
Passage 3:Lvenkrands found himself out of the team for the away draw with Leicester City and remained on the bench. New signing Leon Best was then selected ahead of Lvenkrands for the fixture at St James' Park against Cardiff City. Lvenkrands replaced Best after 60 minutes, and he went on to score the fourth and fifth goals of the game in an emphatic 51 win for Newcastle. He scored the winning goal for Newcastle in their last game of their successful season against Queens Park Rangers finishing off a successful season for both Lvenkrands and Newcastle. He did not start Newcastle's opening Premier League games, starting on the bench. He played alongside Shola Ameobi in a 32 away win against Accrington Stanley in the League Cup. He got his first goal of the season there, scoring the winner with a close range acrobatic volley. After a brief substitute appearance against Blackpool, he started in Newcastle's 43 away win against Chelsea, also in the League Cup. He scored the only goal in the 31 defeat to West Brom. With Carroll injured throughout January, Lvenkrands had a successful month, scoring once in a 50 win over West Ham and playing well a week earlier against Wigan Athletic. After the sale of Carroll to Liverpool in January, Lvenkrands gained more opportunities up front along with the likes of Leon Best and Nile Ranger. He rekindled his partnership with Best upon the injury of Ameobi in February, and Lvenkrands scored in a 20 victory over Birmingham City on 15 February. He continued as a regular striker until the end of the season as Best picked up an ankle injury. He ended his season by scoring in a 33 draw with West Bromwich Albion.
