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.

Passage: On a train trip, lawyer Richard Grant tells fellow passengers that, based on his long experience both prosecuting and defending murder cases, murder is sometimes justified and a clever man should be able to commit it undetected. He is traveling to the isolated estate of his wealthy client and friend, Gordon Rich; his young adult daughter Barbara surprises him at the train station, where she informs him that she has already been there a week.
Grant's view is soon put to the test. Rich asks him to rewrite his will, including bequests to all his former mistresses (except one who is dead already; she was just 16, and Grant believes it was suicide). When Rich explains that he wants a new will because he intends to marry Barbara, Grant is appalled. He repeats what he said on the train. Rich deserves to be murdered, and if that is what it takes to stop the marriage, Grant will do it and get away with it. Rich retorts that if necessary he will retaliate from beyond the grave.
Grant pleads with his daughter, pointing out the great age difference and Rich's indecent character. But she loves Rich and is adamant. Nor has Tommy Osgood, a young man Barbara had been seeing, been able to change her mind.
At a dinner party that night, Rich announces the wedding and says it will take place in the morning. His longtime girlfriend, Marjorie West, is dismayed, but after the party he assures her that, as usual, he will return to her once he exhausts his obsession with Barbara. He is only marrying Barbara because she would not go to bed with him otherwise.
Rich orders two servants to watch Grant's bungalow on the estate, but Grant uses a cutout mounted on a record player to cast a moving shadow on the curtain to make it appear that he is pacing restlessly, and slips back to the main house. Meanwhile, Rich goes to Barbara's room. He loses control and grabs her roughly; she recoils in disgust and he leaves. 
Question: What is the full name of the person who is surprised by someone at the train station?

Ex Output:
Richard Grant.

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?

Ex Output:
North Pole.

Passage: In the 1970s, the Japanese Antarctic Research Expedition (JARE) group designed several drills using side-mill cutters.  These are toothed gears that are driven from the rotation of the main drill motor via 45° spiral gears; their axis of rotation is horizontal, and they are placed so that the teeth cut four vertical slots in the borehole wall.  Guide fins higher on the sonde travel in these slots and provide the antitorque.  The design was effective at preventing rotation of the sonde, but it proved to be almost impossible to realign the guide fins with the existing slots when tripping in.  Misalignment increased the chance of the drill getting stuck in the borehole; and there was also a risk of ice cuttings from the mill cutters jamming in between the drill and the borehole wall, causing the drill to get stuck.  The system was used again in a drill developed in China in the 1980s and 1990s, but the problems inherent in the design are now considered insuperable and it is no longer in use.The most recent anti-torque system design is the use of U-shaped blades, made of steel and fixed vertically to the sides of the sonde.  Initial implementations ran into problems with thin blades bending too easily, and thick blades providing too much resistance to vertical movement of the sonde, but the final design can generate strong resistance to torque in both firn and ice.Drills may be designed with more than one anti-torque system in order to take advantage of the different performance of the different designs in different kinds of snow and ice.  For example, a drill may have skates to be used in hard firn or ice, but also have a leaf-spring system, which will be more effective in soft firn. 
Question: What are the initials for the group that designed several drills using side-mill cutters?

Ex Output:

JARE.
