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: 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?

A: Baleen.

Q: Passage: Nansen's Fram expedition of 1893–96 was an attempt by the Norwegian explorer Fridtjof Nansen to reach the geographical North Pole by harnessing the natural east–west current of the Arctic Ocean. In the face of much discouragement from other polar explorers, Nansen took his ship Fram to the New Siberian Islands in the eastern Arctic Ocean, froze her into the pack ice, and waited for the drift to carry her towards the pole.  Impatient with the slow speed and erratic character of the drift, after 18 months Nansen and a chosen companion, Hjalmar Johansen, left the ship with a team of dogs and sledges and made for the pole. They did not reach it, but they achieved a record Farthest North latitude of 86°13.6′N before a long retreat over ice and water to reach safety in Franz Josef Land. Meanwhile, Fram continued to drift westward, finally emerging in the North Atlantic Ocean.
The idea for the expedition had arisen after items from the American vessel Jeannette, which had sunk off the north coast of Siberia in 1881, were discovered three years later off the south-west coast of Greenland. The wreckage had obviously been carried across the polar ocean, perhaps across the pole itself. Based on this and other debris recovered from the Greenland coast, the meteorologist Henrik Mohn developed a theory of transpolar drift, which led Nansen to believe that a specially designed ship could be frozen in the pack ice and follow the same track as Jeannette wreckage, thus reaching the vicinity of the pole.
Nansen supervised the construction of a vessel with a rounded hull and other features designed to withstand prolonged pressure from ice. The ship was rarely threatened during her long imprisonment, and emerged unscathed after three years. The scientific observations carried out during this period contributed significantly to the new discipline of oceanography, which subsequently became the main focus of Nansen's scientific work. Fram's drift and Nansen's sledge journey proved conclusively that there were no significant land masses between the Eurasian continents and the North Pole, and confirmed the general character of the north polar region as a deep, ice-covered sea. Although Nansen retired from exploration after this expedition, the methods of travel and survival he developed with Johansen influenced all the polar expeditions, north and south, which followed in the subsequent three decades. 
Question: What is the precise geographic name of the pole Nansen and Johansen left the ship with a team of dogs and sledges to make for?

A: North Pole.

Q: Passage: Given the standings of the two men, the painting was received in both social and political terms. A number of writers mentioned Bertin's eventful career, in tones that were, according to art historian Andrew Carrington Shelton, either "bitingly sarcastic [or] fawningly reverential". There were many satirical reproductions and pointed editorials in the following years. Aware of Bertin's support of the July Monarchy, writers at the La Gazette de France viewed the portrait as the epitome of the "opportunism and cynicism" of the new regime. Their anonymous critic excitedly wondered "what bitter irony it expresses, what hardened skepticism, sarcasm and ... pronounced cynicism".Several critics mentioned Bertin's hands. Twentieth-century art historian Albert Boime described them as "powerful, vulturine ... grasping his thighs in a gesture ... projecting ... enormous strength controlled". Some contemporary critics were not so kind. The photographer and critic Félix Tournachon was harshly critical, and disparaged what he saw as a "fantastical bundle of flesh ... under which, instead of bones and muscles, there can only be intestines – this flatulent hand, the rumbling of which I can hear!" Bertin's hands made a different impression on the critic F. de Lagenevais, who remarked: "A mediocre artist would have modified them, he would have replaced those swollen joints with the cylindrical fingers of the first handy model; but by this single alteration he would have changed the expression of the whole personality ... the energetic and mighty nature".The work's realism attracted a large amount of commentary when it was first exhibited. Some saw it as an affront to Romanticism, others said that its small details not only showed an acute likeness, but built a psychological profile of the sitter. Art historian Geraldine Pelles sees Bertin as "at once intense, suspicious, and aggressive". She notes that there is a certain amount of projection of the artist's personality and recalls Théophile Silvestre's description of Ingres; "There he was squarely seated in an armchair, motionless as an Egyptian god carved of granite, his hands stretched wide over parallel knees, his torso stiff, his head haughty". Some compared it to Balthasar Denner, a German realist painter influenced by Jan van Eyck. Denner, in the words of Ingres scholar Robert Rosenblum, "specialised in recording every last line on the faces of aged men and women, and even reflections of windows in their eyes." The comparison was made by Ingres' admirers and detractors alike. In 1833, Louis de Maynard of the Collège-lycée Ampère, writing in the influential L'Europe littéraire, dismissed Denner as a weak painter concerned with hyperrealistic "curiosities", and said that both he and Ingres fell short of the "sublime productions of Ingres' self-proclaimed hero, Raphael."The following year Ingres sought to capitalise on the success of his Bertin portrait. He showed his ambitious history painting The Martyrdom of Saint Symphorian at the 1834 Salon, but it was harshly criticised; even Ingres' admirers offered only faint praise. Offended and frustrated, Ingres declared he would disown the Salon, abandon his residence in Paris for Rome, and relinquish all current positions, ending his role in public life. This petulance was not to last.Bertin bequeathed the portrait to his daughter Louise (1805–1877) on his death. She passed it to her niece Marie-Louise-Sophie Bertin (1836–1893) wife of Jules Bapst, a later director of the Journal des débats. They bequeathed it to their niece Cécile Bapst, its last private owner. In 1897 Cécile sold it to the Musée du Louvre for 80,000 francs. 
Question: What was the final year of private ownership of the painting?

A:
1897.
