[EX Q]: Passage: New York City's Central Park, an oasis that functions as the city's "green lung", was in a state of deterioration in the mid-1970s. Though Central Park had been designated a National Historic Landmark in 1962, at the start of the 1980s, the city lacked the financial resources to spend an estimated US$3,000,000 to restore or even to maintain the park. The nonprofit Central Park Conservancy was founded in 1980, and began a successful campaign to raise renovation funds.In the early 1980s, Parks Commissioner Gordon Davis, responsible for New York City's green areas, and Ron Delsener, one of the city's most influential concert promoters, developed the idea of helping Central Park financially with a free open-air concert, under the legal guidance of Bob Donnelly. The city would use profits from merchandising, television, and video rights to renovate the park. Earlier park performances by Elton John and James Taylor showed that this concept could be a success. Davis authorized the project, and Delsener entered discussions with cable TV channel HBO to decide who would perform.They decided on Simon & Garfunkel, a group that had formed in New York City in the 1960s, and had been one of the most successful folk rock groups through the late 60s/early 70s. Simon & Garfunkel had broken up at the height of their popularity and shortly after the release of their fifth studio album, Bridge Over Troubled Water, which is deemed to be their artistic peak and which topped the 1970 Billboard charts for ten weeks. They had grown apart artistically and did not get along well with each other. In the following eleven years, both continued musical careers as solo artists, and worked together only sporadically on single projects. Garfunkel made brief guest appearances at Simon's concerts, which were always successful.Delsener presented the plan to Paul Simon in the summer of 1981. Simon was enthusiastic about the idea, but questioned whether it could be financially successful, especially given the poor audience attendance of his last project, the autobiographical movie One-Trick Pony. Simon's confidence had declined and he had sought treatment for depression. He questioned whether he and Art Garfunkel could work together, but contacted Garfunkel, who was vacationing in Switzerland. Garfunkel was excited about the idea, and immediately returned to the US.From the promoter's viewpoint, Simon and Garfunkel were ideal choices. Not only were they likely to draw a large crowd to the concert, they also had roots in the city –  both had grown up and gone to school in Forest Hills, Queens. Music critic Stephen Holden pointed out that, unlike artists who had left in pursuit of lifestyles offered by other locales, the two had always been a part of New York City. Both gained inspiration from the cityscape and the cultural variety of New York, and spoke of these influences in their songs. 
Question: What is the name of the city that lacked the financial resources to spend an estimated US$3,000,000 to restore or even maintain its "green lung" at the start of the 1980s??
[EX A]: New York City.

[EX Q]: 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?
[EX A]: Southern Song.

[EX Q]: Passage: Caversham  is one of the older suburbs of the city of Dunedin, in New Zealand's South Island. It is sited at the western edge of the city's central plain at the mouth of the steep Caversham Valley, which rises to the saddle of Lookout Point. Major road and rail routes south lie nearby; the South Island Main Trunk railway runs through the suburb, and a bypass skirts its main retail area, connecting Dunedin's one-way street system with the Dunedin Southern Motorway. The suburb is linked by several bus routes to its neighbouring suburbs and central Dunedin.
The suburb was founded by wealthy pioneer William Henry Valpy, and its name reflects his family connections with the town of Reading, in the English county of Berkshire. Caversham grew rapidly during the Central Otago Gold Rush of the 1860s because of its location on routes south to the Otago hinterland. By the end of the 19th century, Caversham was heavily industrialised, and its population included many skilled or semi-skilled tradespeople. This, combined with the community's strong Protestant roots, led to the area's generally left-leaning political stance. Caversham's early history has been the subject of the Caversham Project, a major historical and archaeological study by the University of Otago. Caversham was a separate borough until 1904, when it was amalgamated with Dunedin city. It is currently administered as part of the city's South Dunedin ward. At a national level, it is part of the Dunedin South electorate.
Caversham is now predominantly residential, with some industrial premises in the east (notably the Hillside Railway Workshops) and a retail district centred on South Road and Hillside Road. Residents are generally of low socio-economic status. Caversham's notable buildings include the heritage listed Lisburn House and several prominent church buildings. Another landmark is the suburb's war memorial, which is the main gate of Caversham School, one of the suburb's two primary schools. Caversham also contains a special-needs school. The nearest secondary schools operate in St Clair, 1 kilometre (0.62 mi) to the south.
Caversham has strong sporting connections, and is the location of Carisbrook, until recently one of Dunedin's main sports venues. The suburb is home to the Southern Rugby Football Club, and gives its name to Caversham Football Club. Several notable sportspeople have associations with Caversham, among them Test cricketer Clarrie Grimmett and father and son rugby union administrators "Old Vic" and "Young Vic" Cavanagh. Other notable people with Caversham connections include politician Thomas Kay Sidey, architect Edmund Anscombe, and surveyor John Turnbull Thomson. 
Question: What is the last name of the father and son rugby administrators that associate with the suburb that was heavily industrialized by the end of the 19th century?
[EX A]:
Cavanagh.
