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.

[EX Q]: 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?
[EX A]: Ferbers.

[EX Q]: Passage: The St. Johns River lies within a humid subtropical zone. In summer months, the temperature ranges from 74 and 92 °F (23 and 33 °C), and between 50 and 72 °F (10 and 22 °C) in the winter, although drops may occur in winter months to below freezing approximately a dozen times. Water temperatures in the river correlate to the air temperatures. The average range of water temperatures is between 50 and 95 °F (10 and 35 °C), rising in the summer months. Where the river widens between Palatka and Jacksonville, wind becomes a significant factor in navigation, and both whitecap waves and calm surface waters are common.Rain occurs more frequently in late summer and early fall. Tropical storms and nor'easters are common occurrences along the Atlantic coast of Florida; the St. Johns River lies between 10 and 30 miles (16 and 48 km) inland, so any storm striking the counties of Indian River north to Duval produces rain that is drained by the St. Johns River. Tropical Storm Fay in 2008 deposited 16 inches (410 mm) of rain in a 5-day period, most of it located near Melbourne. The St. Johns near Geneva in Seminole County rose 7 feet (2.1 m) in four days, setting a record. The river near Sanford rose 3 feet (1 m) in 36 hours. Fay caused severe flooding in the middle basin due not only to the deluge but the flat slopes of the river. Typically, however, the St. Johns basin receives between 50 and 54 inches (1,300 and 1,400 mm) of rain annually, half of it in summer months. The rate of evapotranspiration corresponds to rainfall, ranging between 27 and 57 inches (690 and 1,450 mm) a year, most of it occurring in the summer. 
Question: What is the full name of the place where water temperatures correlate to the air temperatures?
[EX A]: St. Johns River.

[EX Q]: Passage: Handel joined the Hamburg opera house when it was experiencing a period of considerable artistic success. This blossoming followed the arrival of Reinhard Keiser, who had become musical director at the Gänsemarkt in about 1697, and in 1703 succeeded Johann Kusser as the theatre's manager. Born in 1674, Keiser had studied under Johann Schelle and probably Johann Kuhnau at the Thomasschule zu Leipzig.  In 1694 he was employed as a court composer at Brunswick, where in three years he composed seven operas, at least one of which (Mahumeth) was performed in Hamburg. According to Handel's biographer Donald Burrows, Keiser was a good judge of popular taste, with a flair for writing Italian-style arias.  Between 1697 and 1703, prior to Handel's arrival, about a dozen more Keiser operas had been staged at the Gänsemarkt. Despite his on-stage successes, Keiser was an unreliable general manager, with expensive private tastes and little financial acumen, often at odds with his creditors.It is possible that Keiser, who had connections in the Halle area, had heard of Handel and was directly instrumental in securing the latter's post in the Gänsemarkt orchestra; certainly he was a considerable influence on the younger man in the three years that Handel spent in Hamburg. Another important Gänsemarkt colleague was the house composer and singer Johann Mattheson, who noted Handel's rapid progress in the orchestra from back-desk violinist to harpsichord soloist, a role in which, said Mattheson, "he showed himself a man—a thing which no one had before suspected, save I alone". Mattheson was less complimentary on Handel's early efforts at composition: "He composed very long, long arias, and really interminable cantatas", before, it seems, "the lofty schooling of opera ... trimmed him into other fashions". 
Question: What is the last name of the person who was employed as a court composer at Brunswick in 1694?
[EX A]:
Keiser.
