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.
Q: Question: Which version of "I Love You Because" sold more copies, Al Martino's or Leon Payne's? Passage 1:In 1963, he had his biggest U.S. chart success with "I Love You Because", a cover of Leon Payne's 1950 country music hit. Arranged by Belford Hendricks, Martino's version went to number three on the U.S. Billboard Hot 100 chart, and number one on the Easy Listening chart. The album of the same name went top 10 in the Billboard 200. Martino had four other U.S. top 10 hits in 1963 and 1964 - "Painted, Tainted Rose" (1963), "I Love You More and More Every Day", "Tears and Roses", and "Silver Bells" (all 1964). He also sang the title song for the 1964 film, Hush, Hush, Sweet Charlotte. One of his biggest hits was "Spanish Eyes", achieving several gold and platinum discs for sales. Recorded in 1965, the song reached number five on the UK Singles chart when reissued in 1973. The song, with a tune by Bert Kaempfert originally titled "Moon Over Naples", is among the 50 most-played songs worldwide.
 Passage 2:Appleby Castle surrendered to the Scots on 31 July, whereat Lambert, who was still hanging on to the flank of the Scottish advance, fell back from Barnard Castle to Richmond so as to close Wensleydale against any attempt of the invaders to march on Pontefract. All the restless energy of Langdale's horse was unable to dislodge Lambert from the passes or to find out what was behind that impenetrable cavalry screen. The crisis was now at hand. Cromwell had received the surrender of Pembroke Castle on 11 July, and had marched off, with his men unpaid, ragged and shoeless, at full speed through the Midlands. Rains and storms delayed his march, but he knew that the Duke of Hamilton in the broken ground of Westmorland was still worse off. Shoes from Northampton and stockings from Coventry met him at Nottingham, and gathering up the local levies as he went, he made for Doncaster, where he arrived on 8 August, having gained six days in advance of the time he had allowed himself for the march. He then called up artillery from Hull, exchanged his local levies for the regulars who were besieging Pontefract, and set off to meet Lambert. On 12 August he was at Wetherby, Lambert with horse and foot at Otley, Langdale at Skipton and Gargrave, Hamilton at Lancaster, and Sir George Monro with the Scots from Ulster and the Carlisle Royalists (organized as a separate command owing to friction between Monro and the generals of the main army) at Hornby. On 13 August, while Cromwell was marching to join Lambert at Otley, the Scottish leaders were still disputing whether they should make for Pontefract or continue through Lancashire so as to join Lord Byron and the Cheshire Royalists.
 Passage 3:By the late 1960s, the Chinese restaurants and shops around Gerrard Street, Lisle Street, and Little Newport Street had evolved into "Tong Yan Kai", otherwise known as Chinatown. The general public developed a taste for Chinese food during the postwar restaurant boom. In 1963, the Zhongshan Workers' Club opened in the West End, showing films and running classes. The first Chinese New Year celebrations were held in Gerrard Street. The Overseas Chinese Service opened the first specialised agency to assist the Chinese in dealing with the host society by offering a translation and interpreting service. In the 1970s and 1980s, many ethnic Chinese who had settled in Vietnam for generations were forced to leave as "boat people" following the Vietnam War. Many settled in Lewisham, Lambeth, and Hackney, as well as elsewhere in the UK. The 1980s and 1990s saw a migration of academics and professionals from Chinatown to the suburbs of Croydon and Colindale. Since the 1980s, London's Chinatown has been transformed by Westminster City Council to become a major tourist attraction and a cultural focal point of the Chinese community in London. Today over 100,000 Chinese people live in London, and are more evenly dispersed throughout the city and its boroughs. Roughly a quarter of the Chinese population of the United Kingdom now live in London, mainly in the boroughs of Barnet, Haringey, Waltham Forest, Hackney, Southwark and Westminster. Mare Street in Hackney is the hub of a small Vietnamese community. The principal languages of the London Chinese community are Cantonese and Hakka (from the New Territories, Hong Kong, and Vietnam). There are also some speakers of Hokkien, Teochew and Hainanese. The Chinese from the People's Republic of China, Taiwan, and Singapore tend to speak Mandarin (or Putonghua). A large network of Chinese schools and community centres offers support and a means of passing on cultural identity from one generation to the next.
