Q: In this task, you're given a question, along with three passages, 1, 2, and 3. Your job is to determine which passage can be used to answer the question by searching for further information using terms from the passage. Indicate your choice as 1, 2, or 3.
Question: What is the location of the headquarters for the company Bremer Broadcasting sold its station to in 1957? Passage 1:Neugebauer was active in infrared astronomy, and played a leading role in infrared studies of the planets. In addition—and largely through his activities with the Infrared Astronomical Satellite (IRAS) and the Infrared Processing and Analysis Center (IPAC)—he led both ground- and space-based infrared studies of the stars, the Milky Way and other galaxies. Observations by him and his colleagues at Mount Wilson and Palomar observatories revealed thousands of infrared sources in the sky, and afforded the first infrared view of the galactic center. Together with Robert B. Leighton, he completed the Two-Micron Sky Survey, the first infrared survey of the sky, which cataloged more than 5,000 infrared sources. Together with Eric Becklin, he discovered the Becklin–Neugebauer Object, an intense source of infrared radiation in the Orion Nebula that is one of the brightest objects in the sky at wavelengths less than 10 micrometres.
 Passage 2: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 1957–58, 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 stations—WNEW-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.
 Passage 3:When the Qajars had succeeded in restoring the unity of Persia, the sons of the Khan were no more able to maintain their independence like the other Caucasian chiefs and had to choose between Russia and Persia. The Khan of Shirwan, Mustafa, who had already entered into negotiations with Zubov, submitted to the Russians in 1805, who occupied the Persian cities of Derbend and Baku the next year (1806) during the Russo-Persian War (1804-1813), but soon afterwards he made overtures to the Persians and sought help from them. By the Treaty of Gulistan (12/24 October 1813) following the end of the 1804-1813 war, Persia was forced to cede its territories and regions comprising Darband, Quba, Shirwan and Baku, while giving up all claims on them as well. Nevertheless, Mustafa continued to have secret dealings with Persia. It was not until 1820 that his territory was occupied by Russian troops; the Khan fled to Persia and Shemakha was irrevocably incorporated in Russian territory. Iranian anger while being dissatisfied with losing swaths of its integral territories in the North and South Caucasus subsequently sparked the Russo-Persian War (1826-1828), which resulted in another Iranian loss, as well as the ceding of its last remaining territories in the Caucasus comprising what is now Armenia, and southern parts of the contemporary Republic of Azerbaijan. The Treaty of Turkmenchay of 1828 officially ratified the forced ceding of these Iranian territories to Imperial Russia, while it would also mark the official end of millennia long intertwined Iranian hegemony, rule, and influence over the Caucasus region, including Shirvan.
