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.

Q: Passage: On Christmas Eve in 19th-century London, Fred is sliding on ice on a sidewalk. He meets Peter and Tim Cratchit, sons of his uncle Ebenezer's clerk, Bob Cratchit. When Fred reveals who he is, the boys take off in terror. Fred soon arrives at the counting-house of his miserly maternal uncle, Ebenezer Scrooge. After declining an invitation from his nephew to dine with him on Christmas, Scrooge rejects two gentlemen collecting money for charity. That night, Scrooge reluctantly allows his employee Bob Cratchit to have Christmas off with pay but orders him back all the earlier the day after. Later Bob accidentally knocks off Scrooge's hat with a snowball. Scrooge dismisses Bob and withholds a week's pay to compensate for his ruined hat, also demanding a shilling to make up the difference. Bob spends the last of his wages on food for his family's Christmas dinner. 
In his house, Scrooge is confronted by the ghost of his deceased business partner, Jacob Marley, who warns Scrooge to repent his wicked ways or he will be condemned in the afterlife as Marley was. He tells Scrooge he will be haunted by three spirits.
At one o'clock, Scrooge is visited by the youthful Ghost of Christmas Past, who takes him back in time to his early life. Scrooge is shown his unhappiness when he was left to spend the holidays alone at school, and his joy when his sister, Fran, came to take him home for Christmas. The spirit reminds Scrooge that Fran, dead for some years, is the mother of his nephew. Scrooge is shown his early career in business and money lending as an employee under Fezziwig. 
Question: Who explains that there will be three spirits?

A: Jacob Marley.

Q: Passage: The Catacombs of Rome contain most of the surviving Christian art of the Early Christian period, mainly in the form of frescos and sculpted sarcophagi. They show a Christian iconography emerging, initially from Roman popular decorative art, but later borrowing from official imperial and pagan motifs.  Initially, Christians avoided iconic images of religious figures, and sarcophagi were decorated with ornaments, Christian symbols like the Chi Rho monogram and, later, narrative religious scenes. The Early Christians' habit, after the end of their persecution, of building churches (most famously St Peter's, Rome) over the burial places of martyrs who had originally been buried discreetly or in a mass grave perhaps led to the most distinctive feature of Christian funerary art, the church monument, or tomb inside a church. The beliefs of many cultures, including Judaism and Hinduism as well as classical paganism, consider the dead ritually impure and avoid mixing temples and cemeteries (though see above for Moche, and below for Islamic culture).
In the late Middle Ages, influenced by the Black Death and devotional writers, explicit memento mori imagery of death in the forms of skulls or skeletons, or even decomposing corpses overrun with worms in the transi tomb, became common in northern Europe, and may be found in some funerary art, as well as motifs like the Dance of Death and works like the Ars moriendi, or "Art of Dying".  It took until the Baroque period for such imagery to become popular in Italy, in works like the tomb of Pope Urban VIII by Bernini (1628–1647), where a bronze winged skeleton inscribes the Pope's name on a tablet below his enthroned effigy.  As cities became more crowded, bones were sometimes recovered after a period, and placed in ossuaries where they might be arranged for artistic effect, as at the Capuchin Crypt in Rome or the Czech Sedlec Ossuary, which has a chandelier made of skulls and bones. 
Question: What shows a Christian iconography emerging, initially from Roman popular decorative art?

A: surviving Christian art of the Early Christian period.

Q: Passage: The underground punk rock movement inspired countless bands that either evolved from a punk rock sound or brought its outsider spirit to very different kinds of music. The original punk explosion also had a long-term effect on the music industry, spurring the growth of the independent sector. During the early 1980s, British bands like New Order and the Cure that straddled the lines of post-punk and new wave developed both new musical styles and a distinctive industrial niche. Though commercially successful over an extended period, they maintained an underground-style, subcultural identity. In the United States, bands such as Hüsker Dü and their Minneapolis protégés the Replacements bridged the gap between punk rock genres like hardcore and the more melodic, explorative realm of what was then called "college rock".A 1985 Rolling Stone feature on the Minneapolis scene and innovative California hardcore acts such as Black Flag and Minutemen declared, "Primal punk is passé. The best of the American punk rockers have moved on. They have learned how to play their instruments. They have discovered melody, guitar solos and lyrics that are more than shouted political slogans. Some of them have even discovered the Grateful Dead." By the mid-to-late 1980s, these bands, who had largely eclipsed their punk rock and post-punk forebears in popularity, were classified broadly as alternative rock. Alternative rock encompasses a diverse set of styles—including indie rock, gothic rock, dream pop, shoegaze, and grunge, among others—unified by their debt to punk rock and their origins outside of the musical mainstream.As American alternative bands like Sonic Youth, which had grown out of the no wave scene, and Boston's Pixies started to gain larger audiences, major labels sought to capitalize on the underground market that had been sustained by hardcore punk for years. In 1991, Nirvana emerged from Washington State's underground, DIY grunge scene; after recording their first album, Bleach for about $600, the band achieved huge (and unexpected) commercial success with its second album, Nevermind. The band's members cited punk rock as a key influence on their style. "Punk is musical freedom", wrote frontman Kurt Cobain. "It's saying, doing, and playing what you want." Nirvana's success opened the door to mainstream popularity for a wide range of other "left-of-the-dial" acts, such as Pearl Jam and Red Hot Chili Peppers, and fueled the alternative rock boom of the early and mid-1990s. 
Question: What is the name of the band whose members cited punk rock as a key influence on their style?

A:
Nirvana.
