 Passage 2:Casualty is a British medical drama television series that premiered on 6 September 1986 on BBC One. The series was created by Jeremy Brock and Paul Unwin. It is set in the fictional Holby City Hospital, in the equally fictitious city of Holby, and features occasional crossovers of characters and plots with spin-off show Holby City. Casualty follows the professional and personal lives of the doctors, nurses, paramedics, hospital management and patients at Holby General. It features an ensemble cast of regular characters, and began with 10 main characters in its first series, all but two – Charlie Fairhead (played by Derek Thompson) and Lisa "Duffy" Duffin (played by Cathy Shipton) – have since left the show. Many main characters have been written in and out of the series since.

 Passage 3:Anna Kraus, Op. 30 is a radio opera in one act by composer Franz Reizenstein. The work uses an English language libretto by Christopher Hassall to tell the tragic tale of a German woman who is forced to leave her country due to oppression from the Nazi regime, as the Nazis did not like her political views. The opera was commissioned by the British Broadcasting Corporation following the popular success of Reizenstein's 1951 cantata Voices of Night. The opera premiered on 25 July 1952 on BBC Third Programme with conductor Norman Del Mar leading the BBC Symphony Orchestra and singers Victoria Sladen (as Anna) and Lloyd Strauss-Smith (as Pavel). It was submitted by the BBC later that year for the Prix Italia. Critical reaction to the work was mixed. The New Statesman described the work as "engaging" and a "worthwhile experiment". The Annual Register wrote that the opera "suffered from the composer's emotion being too closely engaged in the sufferings of the heroine, a refugee from political oppression".

Question: Did Strings second album 2 have any hits in the United States? Passage 1:The Akademisches Kunstmuseum (English: Academic Museum of Antiquities ) was founded in 1818 and has one of the largest collections of plaster casts of ancient Greek and Roman sculptures in the world. At this time collections of plaster casts were mainly used in the instruction of students at art academies. They were first used in the instruction of university students in 1763 by Christian Gottlob Heyne at University of Göttingen. The Akademisches Kunstmuseum in Bonn was the first of its kind, as at this time collections at other universities were scattered around universities libraries. The first director was Friedrich Gottlieb Welcker, who also held a professorship of archaeology. His tenure was from 1819 until his retirement in 1854. He was succeeded by Otto Jahn and Friedrich Wilhelm Ritschl, who shared the directorship. From 1870 to 1889 Reinhard Kekulé von Stradonitz, nephew of the famous organic chemist Friedrich August Kekulé von Stradonitz, was the director. In 1872 the museum moved to a new building that was formerly used by the department of anatomy. The building was constructed from 1823 to 1830 and designed by Karl Friedrich Schinkel and Hermann Friedrich Waesemann. Other directors of the museum were Georg Loeschcke (from 1889 to 1912), Franz Winter (from 1912 to 1929), Richard Delbrück (from 1929 to 1940), Ernst Langlotz (from 1944 to 1966), Nikolaus Himmelmann (from 1969 to 1994) and Harald Mielsch (since 1994). All directors, with the exception of Friedrich Wilhelm Ritschl held a professorship of archaeology at the university.
 Passage 2:Penzias was born in Munich, Germany, the son of Justine (née Eisenreich) and Karl Penzias, who ran a leather business. His grandparents had come to Munich from Poland and were among the leaders of the Reichenbach Strasse Shul. At age six, he and his brother Gunther were among the Jewish children evacuated to Britain as part of the Kindertransport rescue operation. Some time later, his parents also fled Nazi Germany for the U.S., and the family settled in the Garment District of New York City in 1940. In 1946, Penzias became a naturalized citizen of the United States. He graduated from Brooklyn Technical High School in 1951 and after enrolling to study chemistry at the City College of New York, he changed majors and graduated 1954 with a degree in physics, ranked near the top of his class.
 Passage 3:In 1990 the band signed with EMI Records and released their debut album, Strings. Their initial experiments with synthesised sounds and rhythms were not immediately recognised, although Strings sold 20,000 copies during its first week after release. Two years later the band released their second album, 2, which included the critically acclaimed single "Sar Kiye Yeh Pahar". The song was first aired on MTV Asia, and led the band to widespread fame. After the release of 2, the quartet disbanded to focus on their studies and careers. In 2000 Maqsood and Kapadia released Duur, which revived the band's popularity, and followed it with Dhaani in 2003. This album included the single "Najane Kyun", which was part of the soundtrack for the Hollywood film Spider-Man 2. Following Junoon and Nusrat Fateh Ali Khan, Strings went to India (where they found remixes of one of their early songs playing in clubs). In 2008 Strings released their fifth album, Koi Aanay Wala Hai, with the singles "Yeh Hai Meri Kahani" and "Aakhri Alvida" (included on the soundtracks for Bollywood's Zinda and Shootout at Lokhandwala). The album was co-produced by Bollywood actor John Abraham, and was successful in Pakistan and India.

 Passage 2:Route 104 begins at an intersection with Route 137 in the Bulls Head section of Stamford and heads north, passing by GE Capital, then crossing the Rippowam River, up through North Stamford and onto New York state line.

 Passage 3:Irene was daughter of despotēs Theodore Komnenos Doukas, ruler of Epirus, and Maria Petraliphaina (sister of the sebastokratōr John Petraliphas). In 1230 Irene and her family were captured by the troops of tsar Ivan Asen II of Bulgaria in the battle of Klokotnitsa and they were taken in Tarnovo, where Irene grew up in the Palace. Irene became known for her beauty and the widowed tsar fell in love with her. They married in 1237. According to a Byzantine author, Ivan Asen II loved Irene "no less than Antony loved Cleopatra", and she may have been his mistress for some years before their marriage in 1237. By marrying Irene, Ivan Asen II would have broken church canons, as his daughter, Maria Asanina Komnena, from his marriage to Anna (Anisia) was married to Irene's uncle, Manuel of Thessalonica. There is some evidence that the Bulgarian church opposed the marriage and that a patriarch (called either Spiridon or Vissarion) was deposed or executed by the irate tsar.
