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 first three symphonies, to which Vaughan Williams assigned titles rather than numbers, form a sub-group within the nine, having programmatic elements, absent from the later six.A Sea Symphony (1910), the only one of the series to include a part for full choir, differs from most earlier choral symphonies in that the choir sings in all the movements. The extent to which it is a true symphony has been debated; in a 2013 study, Alain Frogley describes it as a hybrid work, with elements of symphony, oratorio and cantata. Its sheer length—about eighty minutes—was unprecedented for an English symphonic work, and within its thoroughly tonal construction it contains harmonic dissonances that pre-echo the early works of Stravinsky which were soon to follow.A London Symphony (1911–1913) which the composer later observed might more accurately be called a "symphony by a Londoner", is for the most part not overtly pictorial in its presentation of London. Vaughan Williams insisted that it is "self-expressive, and must stand or fall as 'absolute' music". There are some references to the urban soundscape: brief impressions of street music, with the sound of the barrel organ mimicked by the orchestra; the characteristic chant of the lavender-seller; the jingle of hansom cabs; and the chimes of Big Ben played by harp and clarinet. But commentators have heard—and the composer never denied or confirmed—some social comment in sinister echoes at the end of the scherzo and an orchestral outburst of pain and despair at the opening of the finale. Schwartz comments that the symphony, in its "unified presentation of widely heterogeneous elements", is "very much like the city itself". Vaughan Williams said in his later years that this was his favourite of the symphonies.The last of the first group is A Pastoral Symphony (1921). The first three movements are for orchestra alone; a wordless solo soprano or tenor voice is added in the finale. Despite the title the symphony draws little on the folk-songs beloved of the composer, and the pastoral landscape evoked is not a tranquil English scene, but the French countryside ravaged by war. Some English musicians who had not fought in the First World War misunderstood the work and heard only the slow tempi and quiet tone, failing to notice the character of a requiem in the music and mistaking the piece for a rustic idyll. Kennedy comments that it was not until after the Second World War that "the spectral 'Last Post' in the second movement and the girl's lamenting voice in the finale" were widely noticed and understood. 
Question: What is the title of the symphony that draws little on the folk-songs beloved by the composer?
Example Output: A Pastoral Symphony.

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 families—some of which had officials working for the government—used 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. 1206–1227), 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 Ögedei Khan (r.1229–1241), 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 is the full name of the dynasty whose government sponsored major international seaports that were sustaining China's commerce?
Example Output: Southern Song.

Example Input: Passage: Alex Gates is a wine merchant living in Miami who has distanced himself from his alcoholic wife Suzanne with his philandering, and from his stepson Jason with his indifference. Alex is heavily in debt, and hatches a plan to steal a valuable diamond necklace from the house of his clients, the Reese family, where his Cuban mistress Gabriela works. He cases the house during a wine delivery with Jason, who works in Alex's business, although not happily. Jason becomes attracted to Gabriela, unaware of her relationship with his father.
On the day of the heist, Alex and his British safe-cracker partner Victor arrive at the house under the pretense that the Reeses' wine cellar needs repairs, otherwise their wine will be ruined. Gabriela was supposed to let them in, but she was fired the day before. Fortunately, Alex had cultivated a relationship with the security guard and is able to convince him to admit them. Victor sends Alex and the guard off on an errand while he works on the safe, but a second guard becomes suspicious, although Victor is able to complete the job before being discovered.
The pair decide that Alex will pawn the necklace in New York City, and he invites Gabriela to go with him. As he is packing, Suzanne chances upon the airline tickets for him and Gabriela and immediately realizes he is having another affair. The two of them get into a physical alteration and she knocks him out. Deciding to leave him, she empties out his suitcase, where he has hidden the necklace, and uses it for her own clothes. Jason walks in and the two of them flee to the Florida Keys. Upon arriving, they discover the necklace, but Suzanne doesn't want to keep it, even after Jason has it appraised, discovering it is worth $1 million. Jason also visits Gabriela back in Miami, giving her the phone number of the place they are staying at. 
Question: What is the first name of the person who cases the house?
Example Output:
Alex.
