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.

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.

Passage: One of the most persistent and popular stories regarding the Mormon pioneers was about three of the rescuers who helped the pioneers cross Sweetwater River.  The most popular telling, by Solomon Kimball, states:
Three eighteen-year-old boys belonging to the relief party came to the rescue; and to the astonishment of all who saw, carried nearly every member of that ill-fated handcart company across the snow-bound stream. The strain was so terrible, and the exposure so great, that in later years all the boys died from the effects of it. When President Brigham Young heard of this heroic act, he wept like a child, and later declared publicly, "That act alone will ensure C. Allen Huntington, George W. Grant, and David P. Kimball an everlasting salvation in the Celestial Kingdom of God, worlds without end.
This version was quoted by Gordon B. Hinckley, James E. Faust and was previously taught in Sunday School in the LDS Church for both adults and children.Chad Orton notes it would be physically impossible for three boys to carry five hundred people across the river in two hours.  In actuality, the rescue party had several rescuers instead of three, eighteen of which have been positively identified as being at the Sweetwater crossing.  The rescuers brought ten rescue wagons in addition to the wagons the Martin Company had with them. Many survivors wrote about riding the wagons across.  However, because of time constraints, not everyone could ride the wagons. Some were carried, but other survivors wrote that they crossed the river themselves or with the help of people other than the three boys.  The boys mentioned in the story did help some people across, but not "nearly every member" as reported in the mythologized version of the story. While the three boys were among those that helped several across, the ages were wrong. C. Allen Huntington was 24, David P. Kimball was 17, and George W. Grant was 16.  There is no medical evidence that they died from effects of the crossing, and most lived active and relatively long lives.  Outside of Kimball's account, there is no other account of Brigham Young promising everlasting salvation to the rescuers based on a single act. Orton notes that such a promise is inconsistent with church doctrine.  John Thomas notes that Solomon Kimball did not witness the crossing, but relied heavily on other sources, particularly Orson F. Whitney's 1888 account, who also claimed that all of the boys died from the event, even though Huntington was still alive in 1888.

Passage: 3 of Hearts' vocals and image received praise from music critics following the album's release. Billboard described the trio as "possess[ing] angelic voices" and praised 3 of Hearts as "ear candy". D Magazine said the album's pop composition could allow the group to have a crossover appeal, and compared them to the Dixie Chicks. Stephen Thomas Erlewine praised the album as well-constructed and appealing, but criticized several songs – specifically "Over the Edge" – as sounding dated. He positively compared the trio's vocals to those of American band Rascal Flatts, and preferred their wholesome image over the more sexualized one attached to American singer Willa Ford. In a mixed review, Mario Tarradell of the Knight Ridder Tribune described the music as "breezy" and "refreshing", but noted that it was not innovative.Commentators criticized 3 of Hearts and the trio's vocals as generic and lacking an authentic country sound. Country Standard Time's Dan MacIntosh called the album manufactured, describing its content as "impersonal, yet functional, songs". He responded negatively to the lack of attitude in the group's voices, which he dismissed as "girlishly giddy vocals and pop-ish country backing". Editor Tom Roland, writing for the American Bar Association, panned the album's content for its "bright, but shallow declarations of puppy love". Even though he praised the trio as talented, he said their vocals had "none of the life experience that has been a traditional hallmark of country recordings".
