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: A NASA spacecraft lands on an unknown planet and begins to take rock and soil samples. Four aliens discover it and are sucked into the craft through its vacuum tube, after which it makes its way back to Earth. The aliens are able to escape from a government base by using their powers (with which they can destroy or heal anything they touch). During the escape, the youngest one hides in a passing van, occupied by a boy named Eric Cruise who uses a wheelchair, his older brother, Michael, and their single mother, Janet, who are moving to California from Illinois.
Shortly after the Cruise family arrives at their new home, Eric becomes suspicious of the alien's presence. The next morning, he finds that the creature has trashed most of the house and learns its identity, but is blamed alongside his brother by their mother for what has happened. After seeing the creature again, Eric tries to catch up to him, but ends up sliding down a hill and falls into a lake, where he nearly drowns, but is rescued by the alien. Eric is not believed at all when he tries to tell his family about the creature's actions.
Later that night, he sets a trap with the help of his new friend, Debbie, who had also seen the alien. The two trap him inside a vacuum cleaner, which malfunctions and causes the entire neighborhood to suffer a power surge. After the alien is released, Michael now believes Eric, but it leaves before Janet can be convinced. Eric's behavior towards the alien changes after he fixes all of the damage he caused to the house, and leaves behind several newspaper clippings which Eric believes are an attempt to communicate. 
Question: Who fixes the damage to the house?
Example Output: the alien.

Example Input: Passage: The previous convention's lack of Tejano representation fostered a perception that only newcomers to Texas were dissatisfied. The president of the Convention of 1832, Stephen F. Austin, traveled to San Antonio de Béxar to garner support for the changes the convention had requested. Austin found that the Tejano leaders largely agreed with the result of the convention but opposed the methods by which the resolutions had been proposed.  They urged patience; Bustamante was still president and would not look favorably on a petition from settlers who had recently sided with his rival, Santa Anna.As a compromise, the ayuntamiento of San Antonio de Béxar drafted a petition containing similar language to the convention's resolutions.  Following legal norms, they submitted this to Músquiz, who forwarded it to the Mexican Congress in early 1833.  At this time, the federal and state governments were in flux.  Bustamante had resigned the presidency in late December 1832 as part of a treaty to end the civil war.  There was no effective state government.  The governor of Coahuila y Tejas had died in September 1832, and his replacement, federalist Juan Martín de Veramendi, immediately dissolved the state legislature, which had centralist leanings.  Veramendi called elections to seat a new government in early 1833.  Due to the political uncertainty, Austin urged that the federal government be given several months to address the petition.  If no action was eventually taken, he advised that Texas residents would form their own state government, essentially declaring independence from Coahuila, if not from Mexico.Austin's timeframe was endorsed by Tejano leaders, but it did not pacify the Texian settlers.  Towards the end of December, the central committee called for a new convention to meet in San Felipe de Austin in April 1833.  Elections were scheduled for March.  This action disturbed the Tejano leaders, who saw it as a violation of their agreement with Austin.Communities in Texas elected 56 delegates for the new convention.  In a departure from the previous election, San Antonio de Béxar also sent delegates, including James Bowie, the son-in-law of Governor Veramendi.  Bowie, like many of his fellow delegates, was known as an agitator who wanted immediate change.  The majority of the delegates to the previous convention had been more cautious. 
Question: What is the first name of the person who advised that Texas residents would form their own state government?
Example Output: Stephen.

Example Input: Passage: The Red River Trails are less well known today than many other pioneer trails and trade routes in North America, and do not occupy as large a place in folklore as the great western trails in the United States and the fur-trading canoe routes of Canada. They were neither fought over nor the locus of battles (with the exception of the Dakota War of 1862), and although hazardous at times, other trails presented greater dangers. It may be that this relative lack of attention is due to the fact they did not lead to annexation of any territory to either of the nations in which the trails were located.The trails nevertheless were instrumental in the development of central North America. Traffic over the West Plains Trail sustained the Selkirk Settlement in its early years. The trails also gave settlers of that colony and their Métis neighbours a route for migration as well as a highway for trade that was not dependent on the Hudson's Bay Company. As usage grew, old fur trading posts became settlements and new communities were established along the cart routes.  The trails pioneered by the fur brigades accelerated development of Minnesota and North Dakota, and facilitated settlement of the Canadian northwest.
The trails had profound political effects during a time of Anglo-American tension. Both Britain and the U.S. were concerned about each other's cross-border influences. Born out of commercial needs and located by the dictates of geography, the trails helped create and contribute to these international influences and the tensions which resulted. The United States sent military expeditions along the route of the trails to assert national interests in the face of the continued British presence in the northwestern fur posts on soil which the U.S. claimed. The Americans were also concerned about the establishment of Lord Selkirk's colony as well as British claims to the Red River Valley. Finally the U.S. wanted to curtail Britain's attempts to get access to the Mississippi, access implicit in the Treaty of Paris ending the American War of Independence, and which Britain sought into the nineteenth century.  The United States' assertion of dominion over its new territories parried and reversed the British domination of the fur trade in the upper Mississippi valley, which had continued for decades after the Revolutionary War settlement which had assigned those territories to the new nation. 
Question: What is the acronym for the United States?
Example Output:
U.S.
