Question: What is the location of the headquarters for the company Bremer Broadcasting sold its station to in 1957? Passage:On October 6, 1957, Bremer Broadcasting announced it had sold its stations for $3.5 million to National Telefilm Associates (NTA), an early distributor of motion pictures for television, joining its NTA Film Network. On May 7, 1958, channel 13's call sign was changed to WNTA-TV to reflect the new ownership; the radio stations also adopted these call letters. NTA's cash resources enabled WNTA-TV to produce a schedule of programming with greater emphasis on the people and events of New Jersey, compared to the other commercial television stations. NTA also sought to make channel 13 the center of a new commercial network, though during its run the NTA Film Network offered only one night of "in-pattern" network programming, Friday nights in 195758, and for most purposes WNTA served as the New York showcase for nationally syndicated programming and produced several such entries, notably the anthology drama series Play of the Week; the talk show Open End, hosted by David Susskind; children's show The Magic Clown; and a popular dance program emceed by Clay Cole. The station continued to lag behind New York's other independent stationsWNEW-TV (channel 5), WOR-TV (channel 9) and WPIX (channel 11)in terms of audience size, and NTA incurred a large debt load. National Telefilm Associates put the WNTA stations up for sale in February 1961.

Question: How many weeks did the single that peaked at number nine spend on the charts? Passage:"Go Girl" was the first single released from the album. It was originally the lead single from the album, but the single achieved minimum success and was later deemed a promo single. However, the single managed to reach the top of the charts in Japan. The album's official lead single, "Never Ever", which features Young Jeezy, was released in the United States in January 2009 and reached a peak of number nine on the U.S. Hot R&B/Hip-Hop Songs. The second single, "Love Sex Magic", featuring Justin Timberlake, became a worldwide hit, peaking within the top ten in twenty countries including the U.S., where it peaked at number ten on the Billboard Hot 100. It went on to be certified platinum in Australia and received a gold accreditation in New Zealand. It received a nomination for "Best Pop Collaboration with Vocals" at the 52nd Annual Grammy Awards and also for Best Choreography in a Video at the 2009 MTV Video Music Awards. "Like A Surgeon" was the fourth single from the album. The song received no promotion and no single cover nor music video was released. However, the song did manage to peak at number fifty-nine on the Hot R&B/Hip-Hop Songs chart from airplay alone. "Work", the final single, achieved moderate success in international markets.

Question: How old was Itagaki Taisuke when he started The Freedom and People's Rights Movement? Passage:A major proponent of representative government was Itagaki Taisuke, a powerful leader of Tosa forces who had resigned from his Council of State position over the Korean affair in 1873. Itagaki sought peaceful rather than rebellious means to gain a voice in government. Such movements were called The Freedom and People's Rights Movement. He started a movement aimed at establishing a constitutional monarchy and a national assembly. Itagaki and others wrote the Tosa Memorial in 1874 criticizing the unbridled power of the oligarchy and calling for the immediate establishment of representative government. Dissatisfied with the pace of reform after having rejoined the Council of State in 1875, Itagaki organized his followers and other democratic proponents into the nationwide Aikokusha (Society of Patriots) to push for representative government in 1878. In 1881, in an action for which he is best known, Itagaki helped found the Jiyuto (Liberal Party), which favored French political doctrines. In 1882 Okuma Shigenobu established the Rikken Kaishinto (Constitutional Progressive Party), which called for a British-style constitutional democracy. In response, government bureaucrats, local government officials, and other conservatives established the Rikken Teiseito (Imperial Rule Party), a pro-government party, in 1882. Numerous political demonstrations followed, some of them violent, resulting in further government political restrictions. The restrictions hindered the political parties and led to divisiveness within and among them. The Jiyuto, which had opposed the Kaishinto, was disbanded in 1884, and Okuma resigned as Kaishinto president.
