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: Following a life-threatening drug addiction that developed after leaving the Chili Peppers in 1992, Frusciante completed a month of drug rehabilitation at Las Encinas in Pasadena in 1998. Shortly thereafter he was asked to rejoin the band. After several months of writing and recording, the Chili Peppers' next album, Californication was released. The album went on to sell more than 15 million copies worldwide, becoming the Chili Peppers' most successful recording to date. Frusciante's return generated much response from critics, who recognized the album as a commercial revitalization from their previous record, One Hot Minute. A two-year-long, international tour followed, which included several festival appearances, including Woodstock 1999 and Rock in Rio.
The writing and formation of By the Way began immediately following the culmination of Californication's world tour, in the spring of 2001. As with Californication, much of the creation took place in the band members' homes and other practice locations, such as a recording studio stage. Kiedis recalled of the situation: "We started finding some magic and some music and some riffs and some rhythms and some jams and some grooves, and we added to it and subtracted from it and pushed it around and put melodies to it." Frusciante and Kiedis would collaborate for days straight, discussing guitar progressions and sharing lyrics. For Kiedis, "writing By the Way...was a whole different experience from Californication. John was back to himself and brimming with confidence." Prior to recording By the Way, the Chili Peppers decided that they would again have Rick Rubin produce the album. Rubin had, in the past, granted the Chili Peppers creative freedom on their recording material; this was something they thought essential for the album to be unique, and could only occur with his return. 
Question: What was Frusciante asked to rejoin after rehab?
Example Output: the Chili Peppers.

Example Input: Passage: In September 1930 Heseltine moved with Barbara Peache into a basement flat at 12a Tite Street in Chelsea. With no fresh creative inspiration, he worked in the British Museum to transcribe the music of English composer Cipriani Potter, and made a solo version of "Bethlehem Down" with organ accompaniment. On the evening of 16 December Heseltine met with Van Dieren and his wife for a drink and invited them home afterwards. According to Van Dieren, the visitors left at about 12:15 a.m. Neighbours later reported sounds of movement and of a piano in the early morning. When Peache, who had been away, returned early on 17 December, she found the doors and windows bolted, and smelled coal gas. The police broke into the flat and found Heseltine unconscious; he was declared dead shortly afterwards, apparently as the result of coal gas poisoning.An inquest was held on 22 December; the jury could not determine whether the death was accidental or suicide and an open verdict was returned. Most commentators have considered suicide the more likely cause; Heseltine's close friend Lionel Jellinek and Peache both recalled that he had previously threatened to take his life by gas and the outline of a new will was found among the papers in the flat. Much later, Nigel Heseltine introduced a new theory—that his father had been murdered by Van Dieren, the sole beneficiary of Heseltine's 1920 will, which stood to be revoked by the new one. This theory is not considered tenable by most commentators. The suicide theory is supported (arguably), by the (supposed, accepted) fact that Heseltine/Warlock had put his young cat outside the room before he had turned on the lethal gas.Philip Heseltine was buried alongside his father at Godalming cemetery on 20 December 1930. In late February 1931, a memorial concert of his music was held at the Wigmore Hall; a second such concert took place in the following December.In 2011 the art critic Brian Sewell published his memoirs, in which he claimed that he was Heseltine's illegitimate son, born in July 1931 seven months after the composer's death. Sewell's mother, unnamed, was an intermittent girlfriend, a Roman Catholic  who refused Heseltine's offer to pay for an abortion and subsequently blamed herself for his death. Sewell was unaware of his father's identity until 1986. 
Question: What is the last name of the person whose death could not be determined to be accident or suicide?
Example Output: Heseltine.

Example Input: Passage: In writing Young Modern, Johns tried to make the music sound very simple, despite a complex musical structure. The lyrics were written after the music was created, sometimes as late as the day of recording. As Johns dreads writing lyrics, he suggested that the band could produce an instrumental album at some stage in the future. Johns is the band's primary songwriter, and notes that while Joannou and Gillies do not have significant influence on what he writes, they are key to the band's overall sound. For that album, Hamilton co-wrote four songs with Johns including the APRA Award-winning "Straight Lines". Joannou believed that Young Modern was simpler than Diorama but "still as complex underneath with simple pop song elements". He said that much of the band's success resulted from trying to push themselves harder in recording and writing. Self-producing has allowed the band to do so without the pressures of a record label.Gillies notes that Silverchair will often "run the risk of losing fans" with their work, and this was evident in the changes in musical direction in Diorama and Young Modern. However, he described this as a good thing, describing the fact "that we haven't been pigeonholed, and people really don't know what to expect" as one of the attractive elements of the band. Despite the ups and downs of success at a young age, Gillies says the band "appreciate what we've achieved and what we've got" in their careers. The band have received six APRA Awards with Johns winning three songwriting awards at the 2008 ceremony. 
Question: What is the name of the band for which Joannou and Gillies are key to its overall sound?
Example Output:
Silverchair.
