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.

[EX Q]: Passage: As Opeth's primary songwriter and lyricist, vocalist/guitarist Mikael Åkerfeldt heads the direction of Opeth's sound. He was influenced at a young age by the 1970s progressive rock bands King Crimson, Yes, Genesis, Camel, P.F.M., Hawkwind, and Gracious, and by heavy metal bands such as Iron Maiden, Slayer, Death, Black Sabbath, Deep Purple, Celtic Frost, King Diamond, Morbid Angel, Voivod, and, most importantly, Judas Priest. Åkerfeldt considers Judas Priest's Sad Wings of Destiny (1976) the best metal album of all time, and notes that there was a time when he listened only to Judas Priest. While warming up before Opeth concerts, Åkerfeldt frequently sings "Here Come the Tears" from Judas Priest's third album Sin After Sin (1977). Åkerfeldt later discovered progressive rock and folk music, both of which had a profound impact on the sound of the band.Opeth's distinct sound mixes death metal with progressive rock. Steve Huey of AllMusic refers to Opeth's "epic, progressive death metal style". Ryan Ogle of Blabbermouth described Opeth's sound as incorporating "the likes of folk, funk, blues, '70s rock, goth and a laundry list of other sonic oddities into their trademark progressive death style." In his review of Opeth's 2001 album Blackwater Park, AllMusic's Eduardo Rivadavia wrote, "Tracks start and finish in seemingly arbitrary fashion, usually traversing ample musical terrain, including acoustic guitar and solo piano passages, ambient soundscapes, stoner rock grooves, and Eastern-tinged melodies—any of which are subject to savage punctuations of death metal fury at any given moment." Åkerfeldt commented on the diversity of Opeth's music:
I don't see the point of playing in a band and going just one way when you can do everything. It would be impossible for us to play just death metal; that is our roots, but we are now a mishmash of everything, and not purists to any form of music. It's impossible for us to do that, and quite frankly I would think of it as boring to be in a band that plays just metal music. We're not afraid to experiment, or to be caught with our pants down, so to speak. That's what keeps us going.
More recently, Opeth have abandoned their death metal sound resulting in a mellower progressive rock sound. When talking about Heritage, guitarist Fredrik Åkesson stated:
In the beginning it took me a little while to get used to the new idea of the sound, not having any screaming vocals and stuff like that.  But I think the album was necessary for us to do. Maybe the band wouldn't have continued if we hadn't done Heritage.  I think the old Opeth fans understand this album. There's always going to be some haters, but you can't be loved by everyone. Opeth has always been about not repeating ourself. A lot of people don't think Heritage is metal but I think it's metal to go somewhere people don't expect. It doesn't mean we're not embracing the past sound of Opeth.

[EX Q]: Passage: Three princely states bordering India—Nepal, Bhutan and Sikkim—were not integrated into the Republic of India in the period between 1947 and 1950. Nepal had been recognised by the British and the Government of India as being de jure independent. Bhutan had in the British period been considered a protectorate outside the international frontier of India. The Government of India entered into a treaty with Bhutan in 1949 continuing this arrangement, and providing that Bhutan would abide by the advice of the Government of India in the conduct of its external affairs.Historically, Sikkim was a British dependency, with a status similar to that of the other princely states, and was therefore considered to be within the frontiers of India in the colonial period. On independence, however, the Chogyal of Sikkim resisted full integration into India. Given the region's strategic importance to India, the Government of India signed first a Standstill Agreement and then in 1950 a full treaty with the Chogyal of Sikkim which in effect made it a protectorate which was no longer part of India. India had responsibility for defence, external affairs and communications, and ultimate responsibility for law and order, but Sikkim was otherwise given full internal autonomy. In the late 1960s and early 1970s, the Chogyal Palden Thondup Namgyal, supported by the minority Bhutia and Lepcha upper classes, attempted to negotiate greater powers, particularly over external affairs, to give Sikkim more of an international personality. These policies were opposed by Kazi Lhendup Dorji and the Sikkim State Congress, who represented the ethnic Nepali middle classes and took a more pro-Indian view.In April 1973, anti-Chogyal agitation broke out and protestors demanded popular elections. The Sikkim police were unable to control the demonstrations, and Dorji asked India to exercise its responsibility for law and order and intervene. India facilitated negotiations between the Chogyal and Dorji, and produced an agreement, which envisaged the reduction of the Chogyal to the role of a constitutional monarch and the holding of elections based on a new ethnic power-sharing formula. The Chogyal's opponents won an overwhelming victory, and a new Constitution was drafted providing for Sikkim to be associated with the Republic of India. On 10 April 1975, the Sikkim Assembly passed a resolution calling for the state to be fully integrated into India. This resolution was endorsed by 97 percent of the vote in a referendum held on 14 April 1975, following which the Indian Parliament amended the constitution to admit Sikkim into India as its 22nd state.

[EX Q]: Passage: After an April 21, 1995, court hearing on the gun charges, but before McVeigh's release, federal agents took him into custody as they continued their investigation into the bombing. Rather than talk to investigators about the bombing, McVeigh demanded an attorney. Having been tipped off by the arrival of police and helicopters that a bombing suspect was inside, a restless crowd began to gather outside the jail. While McVeigh's requests for a bulletproof vest or transport by helicopter were denied, authorities did use a helicopter to transport him from Perry to Oklahoma City.Federal agents obtained a warrant to search the house of McVeigh's father, Bill, after which they broke down the door and wired the house and telephone with listening devices. FBI investigators used the resulting information gained, along with the fake address McVeigh had been using, to begin their search for the Nichols brothers, Terry and James. On April 21, 1995, Terry Nichols learned that he was being hunted, and turned himself in. Investigators discovered incriminating evidence at his home: ammonium nitrate and blasting caps, the electric drill used to drill out the locks at the quarry, books on bomb-making, a copy of Hunter (a 1989 novel by William Luther Pierce, the founder and chairman of the National Alliance, a white nationalist group) and a hand-drawn map of downtown Oklahoma City, on which the Murrah Building and the spot where McVeigh's getaway car was hidden were marked. After a nine-hour interrogation, Terry Nichols was formally held in federal custody until his trial. On April 25, 1995, James Nichols was also arrested, but he was released after 32 days due to lack of evidence. McVeigh's sister Jennifer was accused of illegally mailing bullets to McVeigh, but she was granted immunity in exchange for testifying against him.Ibrahim Ahmad, a Jordanian-American traveling from his home in Oklahoma City to visit family in Jordan on April 19, 1995, was also arrested, amid concern that Middle Eastern terrorists could have been behind the attack. Further investigation cleared Ahmad of any involvement in the bombing.
