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.
question:
Passage: Avery, who wears a Confederate Army uniform even though he didn't serve in the Civil War, demands that the men who work for rancher John Rutherford avenge him after Rutherford is killed trying to remove a squatter, Corey Everett, from his land.
A passing family, the Ferbers, are traveling by wagon. They meet Corey, who explains that he is homesteading, not squatting, and entitled to the property. Corey defended himself alone with dynamite after Rutherford's men attacked, but Avery became convinced that Corey had many men fighting by his side. He insists his men, led by ranch foreman Hook, call him "General" and obey his orders to launch another attack.
Hannah Ferber doesn't trust Corey at all. Her husband Louis is taken captive by Avery, who tortures and kills him, refusing to believe the truth that Corey is alone. Avery's men realize he is insane and intend to leave, so Avery destroys their water supply. Corey's water is now the only one within hundreds of miles.
Hannah shoots Corey in the shoulder and flees with her son, but returns to nurse him back to health after Louis's body is found. Together they stave off Avery, whose men desert him. Avery dies, astounded to learn that Corey had no other men fighting with him. 
Question: Who meets someone that explains that they are homesteading?
answer:
Ferbers.

Passage: The largest amount of activity recorded for the Lōihi seamount was a swarm of 4,070 earthquakes between July 16 and August 9, 1996. This series of earthquakes was the largest recorded for any Hawaiian volcano to date in both amount and intensity. Most of the earthquakes had moment magnitudes of less than 3.0. "Several hundred" had a magnitude greater than 3.0, including more than 40 greater than 4.0 and a 5.0 tremor.The final two weeks of the earthquake swarm were observed by a rapid response cruise launched in August 1996. The National Science Foundation funded an expedition by University of Hawaii scientists, led by Frederick Duennebier, that began investigating the swarm and its origin in August 1996. The scientists' assessment laid the groundwork for many of the expeditions that followed. Follow-up expeditions to Lōʻihi took place, including a series of manned-submersible dives in August and September.
These were supplemented by a great deal of shore-based research. Fresh rock collected during the expedition revealed that an eruption occurred before the earthquake swarm.Submersible dives in August were followed by NOAA-funded research in September and October 1996. These more detailed studies showed the southern portion of Lōʻihi's summit had collapsed, a result of a swarm of earthquakes and the rapid withdrawal of magma from the volcano. A crater 1 km (0.6 mi) across and 300 m (1,000 ft) deep formed out of the rubble. The event involved the movement of 100 million cubic meters of volcanic material. A region of 10 to 13 km2 (4 to 5 sq mi) of the summit was altered and populated by bus-sized pillow lava blocks, precariously perched along the outer rim of the newly formed crater. "Pele's Vents," an area on the southern side, previously considered stable, collapsed completely into a giant pit, renamed "Pele's Pit". Strong currents make submersible diving hazardous in the region.The researchers were continually met by clouds of sulfide and sulfate. The sudden collapse of Pele's Vents caused a large discharge of hydrothermal material. The presence of certain indicator minerals in the mixture suggested temperatures exceeded 250 °C, a record for an underwater volcano. The composition of the materials was similar to that of black smokers, the hydrothermal vent plumes located along mid-ocean ridges. Samples from mounds built by discharges from the hydrothermal plumes resembled white smokers.The studies demonstrated that the most volcanically and hydrothermally active area was along the southern rift. Dives on the less active northern rim indicated that the terrain was more stable there, and high lava columns were still standing upright. A new hydrothermal vent field (Naha Vents) was located in the upper-south rift zone, at a depth of 1,325 m (4,350 ft). 
Question: What was the name of the new hydrothermal vent field located in the upper-south rift zone?
answer:
Naha Vents.


question:
Passage: Both men were suffering, but Mertz in particular started to feel ill. He complained of stomach pains, and this began to slow them down. Pavlova was killed, leaving only one remaining dog. Mawson decided to lighten their sledge, and much of the equipment—including the camera, photographic films, and all of the scientific equipment save the theodolite—was abandoned. On 29 December, the day they cleared the Ninnis Glacier, the last dog was killed. Mawson recorded: "Had a great breakfast off Ginger's skull—thyroids and brain". Two days later Mawson recorded that Mertz was "off colour"; Mertz wrote that he was "really tired [and] shall write no more".They made 5 miles (8.0 km) on 31 December, no progress for the following two days, and 5 miles more on 3 January. "[The] cold wind frost-bit Mertz's fingers" recorded Mawson, "and he is generally in a very bad condition. Skin coming off legs, etc—so had to camp though going was good." Not until 6 January did they make any more progress; they went 2 miles (3.2 km) before Mertz collapsed. The following day Mawson placed Mertz onto the sledge in his sleeping bag and continued, but was forced to stop and camp when Mertz's condition again deteriorated. Mawson recorded:
He is very weak, becomes more and more delirious, rarely being able to speak coherently. He will eat or drink nothing. At 8 pm he raves & breaks a tent pole. Continues to rave & call 'Oh Veh, Oh Veh' [O weh!, 'Oh dear!'] for hours. I hold him down, then he becomes more peaceful & I put him quietly in the bag. He dies peacefully at about 2 am on morning of 8th.
Strong winds prevented Mawson from continuing for two days. Instead, he prepared for travelling alone, removing the rearmost half from the sledge, and rearranging its cargo. To save having to carry excess kerosene for the stove, he boiled the remainder of the dog meat. Dragging Mertz's body in the sleeping bag from the tent, Mawson constructed a rough cairn from snow blocks to cover it, and used two spare beams from the sledge to form a cross, which he placed on the top. The following day he read the burial service. 
Question: What is the last name of the person who boiled the remainder of the dog meat?
answer:

Mawson.
