In this task, you're given a question, along with a context passage which has extra information available on certain terms mentioned in it. Your job is to determine which sentence(s) from the passage can be used to search for further information needed to answer the question.

Example Input: Question: What country was the creator of "Colonel Jonathan the Saint" born in? Passage:In 1963-1964 Walker was a resident artist at the Oldenburgisches Staatstheater. He then became a resident artist at the Cologne Opera from 1964-1966. Other contracts soon followed with such companies as the Cincinnati Opera, the Houston Grand Opera, the Lyric Opera of Kansas City, the Miami Opera, and the New Orleans Opera among others. In 1971 he created the role of Jonathan Gilourin in the world premiere of Dominick Argento’s Colonel Jonathan the Saint at the Denver Lyric Opera. In 1974 he was handpicked by Sir Georg Solti to sing the role of the Evangelist in Bach's St Matthew Passion with the Chicago Symphony Orchestra (CSO). He returned twice more for performances with Solti and the CSO for performances of the Shepherd in Stravinsky's Oedipus Rex (1976) and Beethoven's Missa Solemnis (1977); the latter of which was recorded for London Records.

Example Output: In 1971 he created the role of Jonathan Gilourin in the world premiere of Dominick Argento’s Colonel Jonathan the Saint at the Denver Lyric Opera

Example Input: Question: Who came first at Asl's race at the Musidora Stakes? Passage:In 1988 Melodist was ridden in all four of her races by Walter Swinburn. She did not run as a three-year-old until 22 May when she was sent to Italy for the Oaks d'Italia over 2400 metres on soft ground at the San Siro racecourse in Milan. The finish of the race was dominated by overseas challengers as Melodist won by one and a half lengths from her fellow British raider Asl (previously second in the Musidora Stakes) with the French-trained Summer Trip a neck away in third. On 9 July Melodist was one of nine runners to contest the Irish Oaks over one and a half miles at the Curragh and started at odds of 11/1. The 2/9 favourite for the race was Diminuendo, ridden by Steve Cauthen, who had won The Oaks by four lengths. Both Melodist and Diminuendo were owned by Sheikh Mohammed and based at Newmarket, but whereas Melodist was trained by Stoute, the favourite was trained by Henry Cecil at Warren Place. The other fancied runners were Dancing Goddess (second in the Irish 1000 Guineas), Miss Boniface (Ribblesdale Stakes) and Silver Lane (Prix de la Grotte). Melodist tracked the leaders before overtaking Miss Boniface before going to the front a furlong and a half from the finish. She faced a strong late challenge from Diminuendo and after a sustained struggle the two fillies crossed the line together with the judge declaring a dead heat.

Example Output: The finish of the race was dominated by overseas challengers as Melodist won by one and a half lengths from her fellow British raider Asl (previously second in the Musidora Stakes) with the French-trained Summer Trip a neck away in third

Example Input: Question: What stone is rated the highest on the Mohs scale of mineral hardness? Passage:Hardstone carving falls under the general category of glyptic art, which covers small carvings and sculpture in all categories of stone. The definition in this context of "hardstone" is unscientific and not very rigid, but excludes "soft" stones such as soapstone (steatite) and minerals such as alabaster, both widely used for carving, as well as typical stones for building and monumental sculpture, such as marble and other types of limestone, and sandstone. These are typically not capable of a fine finish in very small carvings, and would wear in prolonged use. In other contexts, such as architecture, "hard stone" and "soft stone" have different meanings, referring to actual measured hardness using the Mohs scale of mineral hardness and other measures. Some rocks used in architecture and monumental sculpture, such as granite, are at least as hard as the gemstones, and others such as malachite are relatively soft but counted as hardstones because of their rarity and fine colour.

Example Output:
