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.

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?
Southern Song.

Passage: It is the Florida Everglades in 1863. Four deserters of the Confederate Army—Sergeant Todd, Plunkett, Cockney and the Kid—are hiding out. The Colonel, a fellow deserter, appears from the brush with a note from an Indian who has arranged to take him to the ocean so he may be taken to Cuba. When the Indian guide is found dead by Seminoles, the foursome reluctantly join forces with the Colonel in order to reach the coast and ride out the rest of the Civil War.
As the group treks through the dangerous Florida everglades, it's revealed that Plunkett has stolen a large amount of gold from the Confederate army, which Cockney wants to steal from him. The group continues its trek, and it is revealed Cockney is drop-dead afraid of snakes, and being in close contact with them sends him into a paralyzed state. Cockney also reveals that the Colonel deserted after giving drunk orders during the Battle of Murfreesboro, leading to a slaughter. A drought ensues, and when the group reaches water, they also find two dead fellow deserters, killed by Seminoles. The Colonel wishes to bury them, but the foursome disagrees, citing the danger of nearby Seminoles. However, the Kid changes their minds. Soon after, the Colonel begins experiencing troubles, getting a fever, and hallucinating. The group sees smoke, and the Sergeant (the leader of the group) goes to investigate and is attacked by a panther. The rest of the group follows and encounters a seemingly abandoned Seminole settlement. The Colonel, in his deranged state, charges head first into the encampment and is shot by an arrow. The Sergeant rejoins the group and they are attacked by Seminoles. Though they escape, the Colonel dies that evening. After the Colonel's death, the Sergeant declares that it's every man for himself. 
Question: What are the names of the people the Sergeant declares it's every many for himself to?
Plunkett.

Passage: Bristol has two major institutions of higher education: the University of Bristol, a redbrick chartered in 1909, and the University of the West of England, opened as Bristol Polytechnic in 1969, which became a university in 1992. The University of Law also has a campus in the city. Bristol has two further education institutions (City of Bristol College and South Gloucestershire and Stroud College) and two theological colleges: Trinity College, and Bristol Baptist College. The city has 129 infant, junior and primary schools,17 secondary schools, and three learning centres. After a section of north London, Bristol has England's second-highest number of independent school places. Independent schools in the city include Clifton College, Clifton High School, Badminton School, Bristol Grammar School, Queen Elizabeth's Hospital (the only all-boys school) and the Redmaids' School (founded in 1634 by John Whitson, which claims to be England's oldest girls' school).
In 2005 Chancellor of the Exchequer Gordon Brown named Bristol one of six English "science cities",
and a £300 million science park was planned at Emersons Green. Research is conducted at the two universities, the Bristol Royal Infirmary and Southmead Hospital, and science outreach is practiced at We The Curious, the Bristol Zoo, the Bristol Festival of Nature and the Create Centre.The city has produced a number of scientists, including 19th-century chemist Humphry Davy (who worked in Hotwells). Physicist Paul Dirac (from Bishopston) received the 1933 Nobel Prize for his contributions to quantum mechanics. Cecil Frank Powell was the Melvill Wills Professor of Physics at the University of Bristol when he received the 1950 Nobel Prize for, among other discoveries, his photographic method of studying nuclear processes. Colin Pillinger was the planetary scientist behind the Beagle 2 project, and neuropsychologist Richard Gregory founded the Exploratory (a hands-on science centre which was the predecessor of At-Bristol/We The Curious).Initiatives such as the Flying Start Challenge encourage an interest in science and engineering in Bristol secondary-school pupils; links with aerospace companies impart technical information and advance student understanding of design.
The Bloodhound SSC project to break the land speed record is based at the Bloodhound Technology Centre on the city's harbourside. 
Question: What are the full names of the scientists Bristol has produced?

Humphry Davy.
