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.

Example Input: Passage: The Creed familyLouis, Rachel, and their children Ellie and Gagemove from Chicago to rural Ludlow, Maine, after Louis is offered a job as a doctor with the University of Maine. They befriend their elderly neighbor Jud Crandall, who takes them to an isolated pet cemetery (misspelled "sematary") in the forest behind the Creed's new home.
On his first day at work, Louis encounters Victor Pascow, a jogger who has been mortally injured after being hit by a truck. He warns Louis about the pet cemetery before he dies, calling Louis by name despite the fact they have not previously met. That night, Pascow comes to Louis as a ghost and leads him to the Pet Sematary, warning him not to cross the barrier because the ground beyond is "sour". Louis awakens, assuming it was a dream, but notices his feet are covered in dirt.
During Thanksgiving while the family is gone, Ellie's cat, Church, is run down on the highway. Realizing that Ellie will be devastated, Jud takes Louis beyond the cemetery and deep into the woods, where they reach an ancient Micmac burial ground. Jud instructs Louis to bury the cat and warns him not to tell anyone else about what they have done. The next day a reanimated Church returns to the house, a shell of what he was before; he stinks, moves sluggishly, and is vicious towards Louis. Jud explains that as a boy he himself revived his beloved pet dog in the Micmac ground, and that although the cat might be different, it will save Ellie the grief of losing her favorite pet.
Sometime later, the young Gage is killed by a truck along the same highway. The family is devastated, and Jud anticipates that Louis is considering burying his son in the Micmac ground, although Louis denies it. Jud believes that introducing Louis to the ritual ground aroused the malevolent forces present there, which caused Gage's death.
Question: Who befriends an elderly neighbor?
Example Output: Louis.

Example Input: Passage: Although weakened and pushed south beyond the Huai River, the Southern Song found new ways to bolster its strong economy and defend itself against the Jin dynasty. It had able military officers such as Yue Fei and Han Shizhong. The government sponsored massive shipbuilding and harbor improvement projects, and the construction of beacons and seaport warehouses to support maritime trade abroad, including at the major international seaports, such as Quanzhou, Guangzhou, and Xiamen, that were sustaining China's commerce.To protect and support the multitude of ships sailing for maritime interests into the waters of the East China Sea and Yellow Sea (to Korea and Japan), Southeast Asia, the Indian Ocean, and the Red Sea, it was necessary to establish an official standing navy. The Song dynasty therefore established China's first permanent navy in 1132, with a headquarters at Dinghai. With a permanent navy, the Song were prepared to face the naval forces of the Jin on the Yangtze River in 1161, in the Battle of Tangdao and the Battle of Caishi. During these battles the Song navy employed swift paddle wheel driven naval vessels armed with traction trebuchet catapults aboard the decks that launched gunpowder bombs. Although the Jin forces commanded by Wanyan Liang (the Prince of Hailing) boasted 70,000 men on 600 warships, and the Song forces only 3,000 men on 120 warships, the Song dynasty forces were victorious in both battles due to the destructive power of the bombs and the rapid assaults by paddle wheel ships. The strength of the navy was heavily emphasized after that. A century after the navy was founded it had grown in size to 52,000 fighting marines.
The Song government confiscated portions of land owned by the landed gentry in order to raise revenue for these projects, an act which caused dissension and loss of loyalty amongst leading members of Song society but did not stop the Song's defensive preparations. Financial matters were made worse by the fact that many wealthy, land-owning familiessome of which had officials working for the governmentused their social connections with those in office in order to obtain tax-exempt status.Although the Song dynasty was able to hold back the Jin, a new foe came to power over the steppe, deserts, and plains north of the Jin dynasty. The Mongols, led by Genghis Khan (r. 12061227), initially invaded the Jin dynasty in 1205 and 1209, engaging in large raids across its borders, and in 1211 an enormous Mongol army was assembled to invade the Jin. The Jin dynasty was forced to submit and pay tribute to the Mongols as vassals; when the Jin suddenly moved their capital city from Beijing to Kaifeng, the Mongols saw this as a revolt. Under the leadership of Ogedei Khan (r.12291241), both the Jin dynasty and Western Xia dynasty were conquered by Mongol forces. The Mongols also invaded Korea, the Abbasid Caliphate of the Middle East and the Kievan Rus'.
Question: What people used their social connections with those in office in order to obtain tax-exempt status?
Example Output: wealthy, land-owning families.

Example Input: Passage: In October, Norris ruled that Edwards had improperly taken land from an existing settler to give to a new immigrant. Norris evicted the immigrant, angering many of the colonists. Later that month, another new immigrant was arrested and ordered to leave the country after refusing to purchase a merchant license before trading with the Indian tribes. On November 22, 1826, local militia colonel Martin Parmer and 39 other Edwards colonists entered Nacogdoches and arrested Norris, Sepulveda, and the commander of the small Mexican garrison, charging them with oppression and corruption. Haden Edwards was also arrested for violating his expulsion order but was immediately paroled, possibly as a ploy to disguise his own involvement in the plot. A kangaroo court found the other men guilty, removed them from their positions, and banned them from ever holding another public office. The court disbanded after appointing a temporary alcalde. The actions benefitted Parmer personally; several weeks earlier, after Parmer killed a man in a dispute, Norris had issued a warrant for Parmer's arrest. With Norris removed from office, the arrest warrant was voided.Throughout the fall, Benjamin Edwards had tried to gather support from the Edwards colonists for a potential armed revolt against Mexican authority. Largely unsuccessful, he approached the nearby Cherokee tribe for assistance. Several years earlier, the tribe had applied for title to the lands they that occupied in northern East Texas. They were promised but never given a deed from the Mexican authorities. Benjamin Edwards offered the tribe clear title to all of Texas north of Nacogdoches in exchange for armed support for his plans.On December 16, the Edwards brothers invaded Nacogdoches with only 30 settlers, seizing one building in town, the Old Stone Fort. On December 21, they declared the former Edwards colony to be a new republic, named Fredonia. Within hours of the announcement, the Fredonians signed a peace treaty with the Cherokee, represented by Chief Richard Fields and John Dunn Hunter. Fields and Hunter claimed to represent an additional 23 other tribes and promised to provide 400 warriors. In recognition of the agreement, above the Old Stone Fort flew a new flag containing two stripes (one red, one white) representing the two races. Inscribed on the banner was the motto, "Independence, Liberty, and Justice." Haden Edwards also sent messengers to Louisiana to request aid from the United States military, which refused to intervene. Another emissary sent to invite Stephen F. Austin and his colonists to join the rebellion garnered the rebuke: "You are deluding yourselves and this delusion will ruin you.".
Question: What group applied for title to the land they were occupying but never given a deed from the Mexican authorities?
