Instructions: In this task, you're given passages that contain mentions of names of people, places, or things. Some of these mentions refer to the same person, place, or thing. Your job is to write questions that evaluate one's understanding of such references. Good questions are expected to link pronouns (she, her, him, his, their, etc.) or other mentions to people, places, or things to which they may refer. Do not ask questions that can be answered correctly without understanding the paragraph or having multiple answers. Avoid questions that do not link phrases referring to the same entity. For each of your questions, the answer should be one or more phrases in the paragraph, and it should be unambiguous.
Input: Passage: Looking for a harder-hitting rock sound than that of All That You Can't Leave Behind, U2 began recording their eleventh studio album, How to Dismantle an Atomic Bomb, in February 2003 with producer Chris Thomas. After nine months of work, the band had an album's worth of material ready for release, but they were not satisfied with the results; Mullen said that the songs "had no magic". The group subsequently enlisted Steve Lillywhite to take over as producer in Dublin in January 2004. Lillywhite, along with his assistant Jacknife Lee, spent six months with the band reworking songs and encouraging better performances. Several other producers received credits on the album, including Lanois, Eno, Flood, Carl Glanville, and Nellee Hooper; Bono acknowledged that the involvement of multiple producers affected the record's "sonic cohesion".
Released in November 2004, How to Dismantle an Atomic Bomb received favourable reviews from critics. The album featured lyrics touching on life, death, love, war, faith, and family. It reached number one in 30 countries, including the US, where first-week sales of 840,000 copies nearly doubled those of All That You Can't Leave Behind, setting a personal best for the band. Overall, it sold 9 million copies globally. For the album's release, U2 partnered with Apple for several cross-promotions: the first single, "Vertigo", was featured in a television advertisement for the company's iPod music player, while a U2-branded iPod and digital box set exclusive to the iTunes Store were released. "Vertigo" was an international hit, topping the charts in Ireland and the UK, while reaching number two in Canada, number five in Australia, and number 31 in the US. The song won three Grammy Awards, including one for Best Rock Song. Other singles from the album were also hits; "Sometimes You Can't Make It on Your Own", written as a tribute to Bono's late father, went to number one in the UK and Canada, while "City of Blinding Lights" reached number two in both regions. In March 2005, U2 were inducted into the Rock and Roll Hall of Fame by Bruce Springsteen in their first year of eligibility. During his speech, Springsteen said the band had "beaten [the odds] by continuing to do their finest work and remaining at the top of their game and the charts for 25 years".
