Question: Read this and answer the question

During the turbulent reign of Wang Mang, Han lost control over the Tarim Basin, which was conquered by the Northern Xiongnu in AD 63 and used as a base to invade Han's Hexi Corridor in Gansu. Dou Gu (d. 88 AD) defeated the Northern Xiongnu at the Battle of Yiwulu in AD 73, evicting them from Turpan and chasing them as far as Lake Barkol before establishing a garrison at Hami. After the new Protector General of the Western Regions Chen Mu (d. AD 75) was killed by allies of the Xiongnu in Karasahr and Kucha, the garrison at Hami was withdrawn. At the Battle of Ikh Bayan in AD 89, Dou Xian (d. AD 92) defeated the Northern Xiongnu chanyu who then retreated into the Altai Mountains. After the Northern Xiongnu fled into the Ili River valley in AD 91, the nomadic Xianbei occupied the area from the borders of the Buyeo Kingdom in Manchuria to the Ili River of the Wusun people. The Xianbei reached their apogee under Tanshihuai (檀石槐) (d. AD 180), who consistently defeated Chinese armies. However, Tanshihuai's confederation disintegrated after his death.

When did Chen Mu die?
Answer: AD 75


Problem: Early recommendations for the quantity of water required for maintenance of good health suggested that 6–8 glasses of water daily is the minimum to maintain proper hydration. However the notion that a person should consume eight glasses of water per day cannot be traced to a credible scientific source. The original water intake recommendation in 1945 by the Food and Nutrition Board of the National Research Council read: "An ordinary standard for diverse persons is 1 milliliter for each calorie of food. Most of this quantity is contained in prepared foods." More recent comparisons of well-known recommendations on fluid intake have revealed large discrepancies in the volumes of water we need to consume for good health. Therefore, to help standardize guidelines, recommendations for water consumption are included in two recent European Food Safety Authority (EFSA) documents (2010): (i) Food-based dietary guidelines and (ii) Dietary reference values for water or adequate daily intakes (ADI). These specifications were provided by calculating adequate intakes from measured intakes in populations of individuals with “desirable osmolarity values of urine and desirable water volumes per energy unit consumed.” For healthful hydration, the current EFSA guidelines recommend total water intakes of 2.0 L/day for adult females and 2.5 L/day for adult males. These reference values include water from drinking water, other beverages, and from food. About 80% of our daily water requirement comes from the beverages we drink, with the remaining 20% coming from food. Water content varies depending on the type of food consumed, with fruit and vegetables containing more than cereals, for example. These values are estimated using country-specific food balance sheets published by the Food and Agriculture Organisation of the United Nations. Other guidelines for nutrition also have implications for the beverages we consume for healthy hydration- for example, the World Health Organization (WHO) recommend that added sugars should represent no more than 10% of total energy intake.
How much water should be taken in for each calorie of food that is consumed?
The answer is the following: 1 milliliter


The exact nature of relations between Tibet and the Ming dynasty of China (1368–1644) is unclear. Analysis of the relationship is further complicated by modern political conflicts and the application of Westphalian sovereignty to a time when the concept did not exist. Some Mainland Chinese scholars, such as Wang Jiawei and Nyima Gyaincain, assert that the Ming dynasty had unquestioned sovereignty over Tibet, pointing to the Ming court's issuing of various titles to Tibetan leaders, Tibetans' full acceptance of these titles, and a renewal process for successors of these titles that involved traveling to the Ming capital. Scholars within China also argue that Tibet has been an integral part of China since the 13th century and that it was thus a part of the Ming Empire. But most scholars outside China, such as Turrell V. Wylie, Melvin C. Goldstein, and Helmut Hoffman, say that the relationship was one of suzerainty, that Ming titles were only nominal, that Tibet remained an independent region outside Ming control, and that it simply paid tribute until the Jiajing Emperor (1521–1566), who ceased relations with Tibet.
Who were Wang Jiawei and Nyima Gyaincain?
Mainland Chinese scholars


Input: Plymouth
The Elizabethan navigator, Sir Francis Drake was born in the nearby town of Tavistock and was the mayor of Plymouth. He was the first Englishman to circumnavigate the world and was known by the Spanish as El Draco meaning "The Dragon" after he raided many of their ships. He died of dysentery in 1596 off the coast of Puerto Rico. In 2002 a mission to recover his body and bring it to Plymouth was allowed by the Ministry of Defence. His cousin and contemporary John Hawkins was a Plymouth man. Painter Sir Joshua Reynolds, founder and first president of the Royal Academy was born and educated in nearby Plympton, now part of Plymouth. William Cookworthy born in Kingsbridge set up his successful porcelain business in the city and was a close friend of John Smeaton designer of the Eddystone Lighthouse. On 26 January 1786, Benjamin Robert Haydon, an English painter who specialised in grand historical pictures, was born here. The naturalist Dr William Elford Leach FRS, who did much to pave the way in Britain for Charles Darwin, was born at Hoe Gate in 1791.

In what year did Sir Francis Drake die?
Output: 1596


Input: Article: Gesamtschulen might put bright working class students at risk according to several studies. It could be shown that an achievement gap opens between working class students attending a comprehensive and their middle class peers. Also working class students attending a Gymnasium or a Realschule outperform students from similar backgrounds attending a comprehensive. However it is not students attending a comprehensive, but students attending a Hauptschule, who perform the poorest.

Now answer this question: Who could be made vulnerable by the Gasemtschulen?

Output: bright working class students


Problem: A mandolin (Italian: mandolino pronounced [mandoˈliːno]; literally "small mandola") is a musical instrument in the lute family and is usually plucked with a plectrum or "pick". It commonly has four courses of doubled metal strings tuned in unison (8 strings), although five (10 strings) and six (12 strings) course versions also exist. The courses are normally tuned in a succession of perfect fifths. It is the soprano member of a family that includes the mandola, octave mandolin, mandocello and mandobass.
How many courses does a mandolin commonly have? 
The answer is the following:
four
