Example Input: Question: Did the man who founded the strong LDP faction and the man whose hands it later fell into both serve as Prime Minister of Japan? Passage 1:In 1922, Heitler began his study of physics at the Karlsruhe Technische Hochschule, in 1923 at the Humboldt University of Berlin, and in 1924 at the Ludwig Maximilian University of Munich (LMU), where he studied under both Arnold Sommerfeld and Karl Herzfeld. The latter was his thesis advisor when he obtained his doctorate in 1926; Herzfeld taught courses in theoretical physics and one in physical chemistry, and in Sommerfeld's absence often took over his classes. From 1926 to 1927, he was a Rockefeller Foundation Fellow for postgraduate research with Niels Bohr at the Institute for Theoretical Physics at the University of Copenhagen and with Erwin Schrödinger at the University of Zurich. He then became an assistant to Max Born at the Institute for Theoretical Physics at the University of Göttingen. Heitler completed his Habilitation, under Born, in 1929, and then remained as a Privatdozent until 1933. In that year, he was let go by the university because he was Jewish.
 Passage 2:Hashimoto became a key figure in the strong LDP faction founded by Kakuei Tanaka in the 1970s, which later fell into the hands of Noboru Takeshita, who then was tainted by the Recruit scandal of 1988. In 1991, the press had discovered that one of Hashimoto's secretaries had been involved in an illegal financial dealing. Hashimoto retired as Minister of Finance from the Second Kaifu Cabinet. Following the collapse of the bubble economy, the LDP momentarily lost power in 1993/94 during the Hosokawa and Hata anti-LDP coalition cabinets negotiated by LDP defector Ichirō Ozawa. Hashimoto was brought back to the cabinet when the LDP under Yōhei Kōno returned to power in 1994 by entering a ruling coalition with traditional archrival Japanese Socialist Party (JSP), giving the prime ministership to the junior partner, and the minor New Party Harbinger (NPH). Hashimoto became Minister of International Trade and Industry in the Murayama Cabinet of Tomiichi Murayama. As the chief of MITI, Hashimoto made himself known at meetings of APEC and at summit conferences.

Example Input: Question: How old was Wight when Smith died? Passage 1:"I Miss You" is a pop music song with a length of three minutes and fifty-eight seconds. It is a ballad that maintains low-key with an acoustic styling. "I Miss You" is influenced by elements of the country music genre; nevertheless, it has a rock music-based musical arrangement, relying prominently on a gentle strumming guitar for instrumentation. Written in the key of B♭ major but will transpose at the key of C major at the end of the bridge, "I Miss You" is set in common time with a tempo of 85 beats per minute. Cyrus' low and throaty vocals span a one octave, ranging from G to B. The song has the following chord progression, B–Gm–F–F–Fsus.
 Passage 2:Lyman Wight (May 9, 1796 – March 31, 1858) was an early leader in the Latter Day Saint movement. He was the leader of the Latter Day Saints in Daviess County, Missouri, in 1838. In 1841, he was ordained a member of the Quorum of the Twelve Apostles. After the death of Joseph Smith resulted in a succession crisis, Wight led his own break-off group of Latter Day Saints to Texas, where they created a settlement. While in Texas, Wight broke with the main body of the group led by Brigham Young. Wight was ordained president of his own church, but he later sided with the claims of William Smith, and eventually of Joseph Smith III. After his death, most of the "Wightites" (as members of this church were called) joined with the Reorganized Church of Jesus Christ of Latter Day Saints.
 Passage 3:However, before the season began, Gresham suffered a season-ending injury. During the season opener against BYU, Bradford suffered an injury to his shoulder that forced him to sit out the next several games. The Sooners would go on to lose that game and their fourth game against Miami. Bradford returned for game number five against Baylor, but reinjured his shoulder the next week against Texas, ending his season and giving the Sooners their third loss of the season. The Sooners would continue to suffer many injuries throughout the remainder of the season including losing offensive linemen Jarvis Jones and Brody Eldridge, and defensive players Tom Wort, DeMarcus Granger and Auston English for the season. With freshman Landry Jones now leading the offense, the Sooners would go on win every home game from that point forward, including a season-ending win over in-state rival Oklahoma State, extending their NCAA-leading home winning streak to 30 games. However, the Sooners would also lose all but one of their away games. Oklahoma ended the regular season with seven wins and five losses (5–3 in the Big 12). The game marked Oklahoma's third appearance in the Sun Bowl. They were a perfect 2-0 in their previous games. In 1981, they defeated Houston 40–14, and in 1993, they defeated Texas Tech 41–10.

Example Input: Question: When did the television programme on Channel Four where The Proclaimers made an appearance first come on the air? Passage 1:"Right Now" was written by Blige and English musicians Sam Smith, James Napier, and brothers Guy and Howard Lawrence from electronic music duo Disclosure. Production of the song was helmed by Disclosure, while American record producer Rodney "Darkchild" Jerkins was consulted for vocal production. "Right Now" was recorded at Metropolis Studios and at MusicBox Studios in London. Production of the song was motivated by "F for You", the fourth single from Disclosure's debut studio album, Settle (2013). In late 2013, Blige saw the duo's single their Vevo video site, and got in touch with them about covering the song. The resulting duet, largely composed by Blige, became a top ten hit on the UK Dance Chart. Inspired by its response, Blige initially hoped to record an extended play with the duo, though her label encouraged her to enhance recording overseas and soon it was announced that Blige would move to London to experiment with a new sound with a host of young British acts.
 Passage 2:The pair came to public attention when an Inverness-based fan sent their demo to the English band the Housemartins, who were impressed enough to invite the Proclaimers on their 1986 United Kingdom tour. The exposure of the tour won them a January 1987 appearance on the British pop music television programme The Tube on Channel Four; "Letter from America" peaked at number three in the UK Singles Chart, while the album This Is the Story went gold. The follow-up album Sunshine on Leith featured the singles "I'm Gonna Be (500 Miles)", which went to number one in Australia and New Zealand, and "I'm On My Way". They had a hit with their EP King of the Road, which reached number nine in the UK in 1990. "I'm Gonna Be (500 Miles)" belatedly peaked at number three on the Billboard Hot 100 in August 1993, after appearing in the movie Benny & Joon, becoming their only charted single in the United States. After seven low-profile years, they released their comeback album Persevere in 2001.
 Passage 3:As a retailer, Marcus believed strongly in making his store into a place where everything a customer needed could be found and, if necessary, brought to the customer's front door. He was said to have helped one customer discover the shoe size of Queen Elizabeth II so as to give the gift of stockings and a pair of shoes, and he ordered that the store stock such items as a set of Steuben plates with the Mexican national crest, "because sooner or later somebody will be going to call on the President of Mexico and need a proper gift." He personally delivered a fur coat to a St. Louis, Missouri, customer who could not make the trip to Dallas. Another story often recounted is that of a shopper who, in searching for a present for his wife, said that he was not sure what to buy, but that he would know it when he saw it. In response, Marcus inquired about the woman's clothing sizes and asked the customer to wait briefly. Taking an oversized brandy snifter from a display, Marcus gathered cashmere sweaters of various colors, arranged them in imitation of a pousse-café, topped with a white angora sweater to simulate whipped cream, and in place of a cherry, garnished the concoction with a 10-karat ruby ring, at a total cost of $25,350, which the customer gladly paid. When one customer decided his Christmas purchases were not sufficiently impressive, Marcus helped to arrange a full duplication of the store's display window, complete with mannequins and lighting, inside the man's home.
