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: Twist's mother dies in childbirth in the middle of nowhere. Fearing blame, the locals bury her in an unmarked grave and drop the baby at a rural orphanage, where he is named Twist.
Growing up in the dusty wastes of the Swartland, sold from orphanage into child labour on the farms, and later to a rural undertaker, Twist finally takes his fate into his own hands and escapes to Cape Town. Wide eyed at the wonders of the city, he falls in with Fagin - an ancient Ethiopian, Rastafarian, who runs a network of child thieves. His new friend Dodger teaches him the tricks of the trade, but the inexperienced Twist is caught trying to steal from Ebrahim Bassedien.
Although neither understand it, there is a strange affinity between this old man - who has lost his daughter - and the young boy who never knew his mother. Bassedien takes the little stroller in and for a moment it seems that the trauma is over - as the little boy encounters love for the first time in his short and brutal life.
Enter Monks - the only person who knows Twist's true identity. He is paying Fagin to keep the little boy marginalised. If he ends up in jail or dead on the street, so much the better, for Monks stands to lose his inheritance if anybody ever discovers that Twist is Bassedien's grandson.
The brutal gangster Bill Sykes, and his prostitute girlfriend, Nancy, steal Twist back for Fagin, and the struggle for a little boy's soul begins in earnest.

Ex Output:
What person never knew his mother?

Passage: Opeth was formed as a death metal band in 1989 in Stockholm, Sweden, by lead vocalist David Isberg. Isberg asked former Eruption band member Mikael Åkerfeldt, who was just 16 years old at the time, to join Opeth as a bassist. When Åkerfeldt showed up to practice on the day after Isberg invited him, it became clear that Isberg had not told the band members, including the band's current bassist, that Åkerfeldt would be joining the band. An ensuing argument led to all members but Isberg and Åkerfeldt leaving to form a new project. The band name was derived from the word "Opet", taken from the Wilbur Smith novel The Sunbird. In this novel, Opet is the name of a fictional Phoenician city in South Africa translated as "City of the Moon".
Isberg and Åkerfeldt recruited drummer Anders Nordin, bassist Nick Döring, and guitarist Andreas Dimeo. Unsatisfied with Opeth's slow progress, Döring and Dimeo left the band after their first performance, and were replaced by guitarist Kim Pettersson and bassist Johan De Farfalla. After the next show, De Farfalla left Opeth to spend time with his girlfriend in Germany, and was initially replaced by Mattias Ander, before Åkerfeldt's friend Peter Lindgren took on the role of bassist. Rhythm guitarist Kim Pettersson left following the band's next performance, and Lindgren switched to guitar, with the role of bassist falling to Stefan Guteklint. The following year, David Isberg left the band citing "creative differences".Following Isberg's departure, Åkerfeldt took over vocal duties and he, Lindgren, and Nordin spent the next year writing and rehearsing new material. The group began to rely less on the blast beats and aggression typical of death metal, and incorporated acoustic guitars and guitar harmonies into their music; developing the core sound of Opeth. Bassist Guteklint was dismissed by the band after they signed their first record deal with Candlelight Records in 1994. Opeth initially employed former member De Farfalla as a session bassist for their demo recordings, and he went on to join on a full-time basis following the release of Opeth's debut album, "Orchid", in 1995.

Ex Output:
What is the last name of the bassist who replaced the band member that was dismissed in 1994?

Passage: Shostakovich scholar Laurel Fay suggests that this concert was "an event of legendary import all by itself". Journalist Michael Tumely calls it "a legendary moment in Soviet political and military history". Critic U.S. Dhuga suggests that this performance "was popularly – and, of course, officially – recognized as the prelude to actual victory over the Germans". The blockade was breached in early 1943 and ended in 1944. Eliasberg concurred with Dhuga's assessment, saying that "the whole city had found its humanity ... in that moment, we triumphed over the soulless Nazi war machine". There was no official recognition of the significance of the concert: one musician noted that afterwards "there was no feedback, nothing until 1945".Shostakovich's Symphony No. 7 enjoyed a measure of popularity throughout the Western world during the war, but from 1945 it was rarely performed outside the Soviet Union. It became a point of controversy in the 1980s after Solomon Volkov's Testimony suggested it was a critique not of the Nazis, but of the Soviet government. The veracity of Volkov's account, which he claims is rooted in interviews with Shostakovich, has been debated. Other issues of contention about the symphony include whether it was inspired by the attack on Leningrad (as Soviet authorities and official accounts had asserted) or planned earlier and repurposed for propaganda, as well as its artistic merit compared to Shostakovich's other works.The première made Eliasberg a "hero of the city". Shortly after the concert, he married Nina Bronnikova, who had played the piano part. But once the siege ended and the Philharmonic returned to Leningrad, he fell from favour. The conductor of the Philharmonic, Yevgeny Mravinsky, had him fired in 1950 because he envied Eliasberg's popular acclaim. Eliasberg was a "poor and largely forgotten" travelling conductor when he died in 1978. However, at the fifty-year anniversary of the première his remains were moved to the prestigious Volkovskoye or Alexander Nevsky Cemetery, the result of a campaign by orchestra archivist Galina Retrovskaya, conductor Yuri Temirkanov, and St. Petersburg mayor Anatoly Sobchak. Sarah Quigley fictionalized Eliasberg's wartime career in her historical novel The Conductor.Surviving performers participated in reunion concerts in 1964 and 1992, playing "from the same seats in the same hall". Shostakovich attended the first reunion concert on 27 January 1964. Twenty-two musicians and Eliasberg performed the symphony, and instruments were placed on the other chairs to represent those participants who had died since the première. The 1992 performance featured the 14 remaining survivors. The 1942 concert was also commemorated in the 1997 film The War Symphonies: Shostakovich Against Stalin. There is a small museum dedicated to the event at School No. 235 in St. Petersburg, which includes a statue of Shostakovich and artefacts from the performance.

Ex Output:
What is the name of the person whose remains were moved to the prestigious Volkovskoye or Alexander Nevsky Cemetery?
