In this task, you're expected to write answers to questions involving multiple references to the same entity. The answer to the question should be unambiguous and a phrase in the paragraph. Most questions can have only one correct answer.

Example Input: Passage: The company, retaining the title "Sadler's Wells Opera", opened at the Coliseum on 21 August 1968, with a new production of Mozart's Don Giovanni, directed by Sir John Gielgud. Though this production was not well received, the company rapidly established itself with a succession of highly praised productions of other works. Arlen died in January 1972, and was succeeded as managing director by Lord Harewood.The success of the 1968 Mastersingers was followed in the 1970s by the company's first Ring cycle, conducted by Goodall, with a new translation by Andrew Porter and designs by Ralph Koltai. The cast included Norman Bailey, Rita Hunter and Alberto Remedios. In Harewood's view, among the highlights of the first ten years at the Coliseum were the Ring, Prokofiev's War and Peace, and Richard Strauss's Salome and Der Rosenkavalier.
The company's musical director from 1970 to 1977 was Charles Mackerras. Harewood praised his exceptional versatility, with a range "from The House of the Dead to Patience." Among the operas he conducted for the company were Handel's Julius Caesar starring Janet Baker and Valerie Masterson; five Janacek operas; The Marriage of Figaro with pioneering use of 18th century performing style; Massenet's Werther; Donizetti's Mary Stuart with Baker; and Sullivan's Patience. The company took the production of the last to the Vienna Festival in 1975, along with Britten's Gloriana. Sir Charles Groves succeeded Mackerras as musical director from 1978 to 1979, but Groves was unwell and unhappy during his brief tenure. Starting in 1979, Mark Elder succeeded Groves in the post, and described Groves "immensely encouraging and supportive".A long-standing concern of Arlen and then Harewood was the need to change the company's name to reflect the fact that it was no longer based at Sadler's Wells theatre. Byam Shaw commented "The one major setback the Sadler's Wells Opera Company suffered from its transplant was that unheeding taxi drivers kept on taking their patrons up to Rosebery Avenue".Harewood considered it an elementary rule that "you must not carry the name of one theatre if you are playing in another one." Covent Garden, protective of its status, objected to the suggestion that the Sadler's Wells company should be called "The British National Opera" or "The National Opera", although neither Scottish Opera nor the Welsh National Opera opposed such a change. Eventually the British government decided the matter, and the title "English National Opera" was approved. The company's board adopted the new name in November 1974. In 1977, in response to demand for more opera productions in English provincial cities, a second company was established. It was based at Leeds in northern England, and was known as ENO North. Under Harewood's guidance, it flourished, and in 1981 it became an independent company, Opera North.
Question: What is the first name of the person who unwell and unhappy during his brief tenure?
Example Output: Charles.

Example Input: Passage: To design and build his ship Nansen chose Colin Archer, Norway's leading shipbuilder and naval architect. Archer was well known for a particular hull design that combined seaworthiness with a shallow draught, and had pioneered the design of "double-ended" craft in which the conventional stern was replaced by a point, increasing manoeuvrability. Nansen records that Archer made "plan after plan of the projected ship; one model after another was prepared and abandoned". Finally, agreement was reached on a design, and on 9 June 1891 the two men signed the contract.Nansen wanted the ship in one year; he was eager to get away before anyone else could adopt his ideas and forestall him. The ship's most significant external feature was the roundness of the hull, designed so that there was nothing upon which the ice could get a grip. Bow, stern and keel were rounded off, and the sides smoothed so that, in Nansen's words, the vessel would "slip like an eel out of the embraces of the ice". To give exceptional strength the hull was sheathed in South American greenheart, the hardest timber available. The three layers of wood forming the hull provided a combined thickness of between 24 and 28 inches (6070 cm), increasing to around 48 inches (1.25 metres) at the bow, which was further protected by a protruding iron stem. Added strength was provided by crossbeams and braces throughout the length of the hull.
The ship was rigged as a three-masted schooner, with a total sail area of 6,000 square feet (560 m2). Its auxiliary engine of 220 horse-power was capable of speeds up to 7 knots (13 km/h; 8.1 mph). However, speed and sailing qualities were secondary to the requirement of providing a safe and warm stronghold for Nansen and his crew during a drift that might extend for several years, so particular attention was paid to the insulation of the living quarters. At around 400 gross register tonnage, the ship was considerably larger than Nansen had first anticipated, with an overall length of 128 feet (39 m) and a breadth of 36 feet (11 m), a ratio of just over three to one, giving her an unusually stubby appearance. This odd shape was explained by Archer: "A ship that is built with exclusive regard to its suitability for [Nansen's] object must differ essentially from any known vessel." On 6 October 1892, at Archer's yard at Larvik, the ship was launched by Nansen's wife Eva after a brief ceremony. The ship was named Fram, meaning "Forward".
Question: What is the name of the ship that was rigged as a three-masted schooner, with a total sail area of 6,000 square feet?
Example Output: Fram.

Example Input: Passage: "Smells Like Teen Spirit" was first performed live on April 17, 1991 at the OK Hotel in Seattle, Washington. The performance is featured on the DVD of the 2004 box set With the Lights Out, while shorter clips are included on the Nevermind Classic Albums DVD, as well as the documentary film Hype! As the song's lyrics had not yet been entirely written, there are notable differences between it and the final version. For example, the first performance started with "Come out and play, make up the rules" instead of the eventual opening of "Load up on guns, bring your friends". A recording of the earlier version appears on With the Lights Out and again on Sliver: The Best of the Box. A similar early live performance of the song is found in the documentary 1991: The Year Punk Broke, filmed during a 1991 summer tour in Europe with Sonic Youth.
Nirvana often altered the song's lyrics and tempo for live performances. Some live performances of the song had the line "our little group has always been" changed to "our little tribe has always been", which can be heard on the 1996 live album From the Muddy Banks of the Wishkah. Rolling Stone remarked that the Wishkah version of "Teen Spirit" "[found] Cobain's guitar reeling outside the song's melodic boundaries and sparking new life in that nearly played-out hit". A notable alternate performance of "Smells Like Teen Spirit" occurred on BBC's Top of the Pops in 1991, during which the band refused to mime to the pre-recorded backing track and Cobain sang in a deliberately low voice and altered numerous lyrics in the song (for example, "Load up on guns, bring your friends" became "Load up on drugs, kill your friends"). Cobain later said he was trying to sound like former Smiths frontman Morrissey. When Top of the Pops was cancelled in 2006, The Observer listed Nirvana's performance of "Smells Like Teen Spirit" as the third greatest in the show's history. This performance can be found on the 1994 home video Live! Tonight! Sold Out!!.
Question: What nearly played-out hit did Cobain spark new life into?
Example Output:
Smells Like Teen Spirit.
