Passage: In 1898 the RCM offered Holst a further year's scholarship, but he felt that he had learned as much as he could there and that it was time, as he put it, to "learn by doing". Some of his compositions were published and performed; the previous year The Times had praised his song "Light Leaves Whisper", "a moderately elaborate composition in six parts, treated with a good deal of expression and poetic feeling".Occasional successes notwithstanding, Holst found that "man cannot live by composition alone"; he took posts as organist at various London churches, and continued playing the trombone in theatre orchestras. In 1898 he was appointed first trombonist and répétiteur with the Carl Rosa Opera Company and toured with the Scottish Orchestra. Though a capable rather than a virtuoso player he won the praise of the leading conductor Hans Richter, for whom he played at Covent Garden. His salary was only just enough to live on, and he supplemented it by playing in a popular orchestra called the "White Viennese Band", conducted by Stanislas Wurm.Holst enjoyed playing for Wurm, and learned much from him about drawing rubato from players. Nevertheless, longing to devote his time to composing, Holst found the necessity of playing for "the Worm" or any other light orchestra "a wicked and loathsome waste of time". Vaughan Williams did not altogether agree with his friend about this; he admitted that some of the music was "trashy" but thought it had been useful to Holst nonetheless: "To start with, the very worst a trombonist has to put up with is as nothing compared to what a church organist has to endure; and secondly, Holst is above all an orchestral composer, and that sure touch which distinguishes his orchestral writing is due largely to the fact that he has been an orchestral player; he has learnt his art, both technically and in substance, not at second hand from text books and models, but from actual live experience."With a modest income secured, Holst was able to marry Isobel; the ceremony was at Fulham Register Office on 22 June 1901. Their marriage lasted until his death; there was one child, Imogen, born in 1907. In 1902 Dan Godfrey and the Bournemouth Municipal Orchestra premiered Holst's symphony The Cotswolds (Op. 8), the slow movement of which is a lament for William Morris who had died in October 1896, three years before Holst began work on the piece. In 1903 Adolph von Holst died, leaving a small legacy. Holst and his wife decided, as Imogen later put it, that "as they were always hard up the only thing to do was to spend it all at once on a holiday in Germany". 
Question: What is the name of the person whose orchestral writing, according to Vaughan Williams, is distinguished by a "sure touch" that is "due largely to the fact that he has been an orchestral player"?
answer:
Holst.

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 people used their social connections with those in office in order to obtain tax-exempt status?
answer:
wealthy, land-owning families.


question:
Passage: The St. Johns River lies within a humid subtropical zone. In summer months, the temperature ranges from 74 and 92 °F (23 and 33 °C), and between 50 and 72 °F (10 and 22 °C) in the winter, although drops may occur in winter months to below freezing approximately a dozen times. Water temperatures in the river correlate to the air temperatures. The average range of water temperatures is between 50 and 95 °F (10 and 35 °C), rising in the summer months. Where the river widens between Palatka and Jacksonville, wind becomes a significant factor in navigation, and both whitecap waves and calm surface waters are common.Rain occurs more frequently in late summer and early fall. Tropical storms and nor'easters are common occurrences along the Atlantic coast of Florida; the St. Johns River lies between 10 and 30 miles (16 and 48 km) inland, so any storm striking the counties of Indian River north to Duval produces rain that is drained by the St. Johns River. Tropical Storm Fay in 2008 deposited 16 inches (410 mm) of rain in a 5-day period, most of it located near Melbourne. The St. Johns near Geneva in Seminole County rose 7 feet (2.1 m) in four days, setting a record. The river near Sanford rose 3 feet (1 m) in 36 hours. Fay caused severe flooding in the middle basin due not only to the deluge but the flat slopes of the river. Typically, however, the St. Johns basin receives between 50 and 54 inches (1,300 and 1,400 mm) of rain annually, half of it in summer months. The rate of evapotranspiration corresponds to rainfall, ranging between 27 and 57 inches (690 and 1,450 mm) a year, most of it occurring in the summer. 
Question: What is the full name of the place where water temperatures correlate to the air temperatures?
answer:

St. Johns River.
