TASK DEFINITION: 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.
PROBLEM: Passage: In 1996 the Pumpkins undertook an extended world tour in support of Mellon Collie. Corgan's look during this perioda shaved head, a long sleeve black shirt with the word "Zero" printed on it, and silver pantsbecame iconic. That year, the band also made a guest appearance in an episode of The Simpsons, "Homerpalooza". With considerable video rotation on MTV, major industry awards, and "Zero" shirts selling in many malls, the Pumpkins were considered one of the most popular bands of the time. But the year was far from entirely positive for the band. In May, the Smashing Pumpkins played a gig at the Point Theatre in Dublin, Ireland. Despite the band's repeated requests for moshing to stop, a seventeen-year-old fan named Bernadette O'Brien was crushed to death. The concert ended early and the following night's performance in Belfast was cancelled out of respect for her. However, while Corgan maintained that moshing's "time [had] come and gone", the band would continue to request open-floor concerts throughout the rest of the tour.The band suffered a personal tragedy on the night of July 11, 1996, when touring keyboardist Jonathan Melvoin and Chamberlin overdosed on heroin in a hotel room in New York City. Melvoin died, and Chamberlin was arrested for drug possession. A few days later, the band announced that Chamberlin had been fired as a result of the incident. The Pumpkins chose to finish the tour, and hired drummer Matt Walker and keyboardist Dennis Flemion. Corgan later said the decision to continue touring was the worst decision the band had ever made, damaging both their music and their reputation. Chamberlin admitted in a 1994 Rolling Stone cover story that in the past he'd "gotten high in every city in this country and probably half the cities in Europe." But in recent years, he had reportedly been clean. On July 17, the Pumpkins issued a statement in which they said, "For nine years we have battled with Jimmy's struggles with the insidious disease of drug and alcohol addiction. It has nearly destroyed everything we are and stand for. We wish [him] the best we have to offer". Meanwhile, the band had given interviews since the release of Mellon Collie stating that it would be the last conventional Pumpkins record, and that rock was becoming stale. James Iha said at the end of 1996, "The future is in electronic music. It really seems boring just to play rock music.".
Question: What is the last name of the member of the band that overdose but survived?

SOLUTION: Chamberlin.

PROBLEM: Passage: Whales are a widely distributed and diverse group of fully aquatic placental marine mammals. They are an informal grouping within the infraorder Cetacea, usually excluding dolphins and porpoises. Whales, dolphins and porpoises belong to the order Cetartiodactyla, which consists of even-toed ungulates. Their closest living relatives are the hippopotamuses, having diverged about 40 million years ago. The two parvorders of whales, baleen whales (Mysticeti) and toothed whales (Odontoceti), are thought to have split apart around 34 million years ago. Whales consist of eight extant families: Balaenopteridae (the rorquals), Balaenidae (right whales), Cetotheriidae (the pygmy right whale), Eschrichtiidae (the grey whale), Monodontidae (belugas and narwhals), Physeteridae (the sperm whale), Kogiidae (the dwarf and pygmy sperm whale), and Ziphiidae (the beaked whales).
Whales are creatures of the open ocean; they feed, mate, give birth, suckle and raise their young at sea. So extreme is their adaptation to life underwater that they are unable to survive on land. Whales range in size from the 2.6 metres (8.5 ft) and 135 kilograms (298 lb) dwarf sperm whale to the 29.9 metres (98 ft) and 190 metric tons (210 short tons) blue whale, which is the largest creature that has ever lived. The sperm whale is the largest toothed predator on earth. Several species exhibit sexual dimorphism, in that the females are larger than males. Baleen whales have no teeth; instead they have plates of baleen, a fringe-like structure used to expel water while retaining the krill and plankton which they feed on. They use their throat pleats to expand the mouth to take in huge gulps of water. Balaenids have heads that can make up 40% of their body mass to take in water. Toothed whales, on the other hand, have conical teeth adapted to catching fish or squid. Baleen whales have a well developed sense of "smell", whereas toothed whales have well-developed hearing their hearing, that is adapted for both air and water, is so well developed that some can survive even if they are blind. Some species, such as sperm whales, are well adapted for diving to great depths to catch squid and other favoured prey.
Question: What are the types of whales that use throat pleats to expand the mouth?

SOLUTION: Baleen.

PROBLEM: Passage: Professor John Oldman is packing his belongings onto his truck, preparing to move to a new home. His colleagues show up to give him an impromptu farewell party: Harry, a biologist; Edith, an art history professor and devout Christian; Dan, an anthropologist; Sandy, a historian who is in love with John; Art, an archaeologist; and his student Linda.
As John's colleagues press him to explain the reason for his departure, he picks up from a reference to Magdalenian cultures by Dan and slowly, and somewhat reluctantly, reveals that he is a prehistoric caveman himself from that precise period. He states that he has lived for more than 14 millennia, and that he relocates every ten years to keep others from realizing that he does not age. He begins his tale under the guise of a possible science-fiction story, but eventually stops speaking in hypotheticals and begins answering questions from a first-person perspective. His colleagues refuse to believe his story but accept it as a working hypothesis in order to glean his true intentions. John relates he was a Sumerian for 2000 years, later a Babylonian, and eventually went East to become a disciple of Buddha. He claims to have had a chance to sail with Columbus (admitting that at the time he still believed the earth was flat) and to have befriended Van Gogh (one of whose original paintings he apparently owns, a gift from the artist himself).
Question: What is the full name of the person who said that they once believed the Earth was flat?

SOLUTION:
John Oldman.
