Glacial bodies larger than 50,000 km2 (19,000 sq mi) are called ice sheets or continental glaciers. Several kilometers deep, they obscure the underlying topography. Only nunataks protrude from their surfaces. The only extant ice sheets are the two that cover most of Antarctica and Greenland. They contain vast quantities of fresh water, enough that if both melted, global sea levels would rise by over 70 m (230 ft). Portions of an ice sheet or cap that extend into water are called ice shelves; they tend to be thin with limited slopes and reduced velocities. Narrow, fast-moving sections of an ice sheet are called ice streams. In Antarctica, many ice streams drain into large ice shelves. Some drain directly into the sea, often with an ice tongue, like Mertz Glacier.
At what dimensions are glaciers called ice sheets or continental glaciers?
50,000 km2 (19,000 sq mi)


Input: Paris
As of 2013 the City of Paris had 1,570 hotels with 70,034 rooms, of which 55 were rated five-star, mostly belonging to international chains and mostly located close to the centre and the Champs-Élysées. Paris has long been famous for its grand hotels. The Hotel Meurice, opened for British travellers in 1817, was one of the first luxury hotels in Paris. The arrival of the railroads and the Paris Exposition of 1855 brought the first flood of tourists and the first modern grand hotels; the Hôtel du Louvre (now an antiques marketplace) in 1855; the Grand Hotel (now the Intercontinental LeGrand) in 1862; and the Hôtel Continental in 1878. The Hôtel Ritz on Place Vendôme opened in 1898, followed by the Hôtel Crillon in an 18th-century building on the Place de la Concorde in 1909; the Hotel Bristol on rue de Fabourg Saint-Honoré in 1925; and the Hotel George V in 1928.

Along what major road are most hotels located?
Output: Champs-Élysées


Input: Article: In the inter-war years and after 1940, Hugh Dowding, Air Officer Commanding Fighter Command has received credit for the defence of British air space and the failure of the Luftwaffe to achieve air superiority. However, Dowding had spent so much effort preparing day fighter defences, there was little to prevent the Germans carrying out an alternative strategy by bombing at night. When the Luftwaffe struck at British cities for the first time on 7 September 1940, a number of civic and political leaders were worried by Dowding's apparent lack of reaction to the new crisis.

Now answer this question: What strategy could the German's have used instead of day raids?

Output: bombing at night


Article: Diaz's plans called for the entire city to eventually be modernized or rebuilt in the Porfirian/French style of the Colonia Roma; but the Mexican Revolution began soon afterward and the plans never came to fruition, with many projects being left half-completed. One of the best examples of this is the Monument to the Mexican Revolution. Originally the monument was to be the main dome of Diaz's new senate hall, but when the revolution erupted only the dome of the senate hall and its supporting pillars were completed, this was subsequently seen as a symbol by many Mexicans that the Porfirian era was over once and for all and as such, it was turned into a monument to victory over Diaz.

Question: Who was the man behind the modernization of Mexico City?
Ans: Diaz


Here is a question about this article: Generally, this pattern is a circuit consisting of five "legs" that form a rectangle (two legs and the runway form one side, with the remaining legs forming three more sides). Each leg is named (see diagram), and ATC directs pilots on how to join and leave the circuit. Traffic patterns are flown at one specific altitude, usually 800 or 1,000 ft (244 or 305 m) above ground level (AGL). Standard traffic patterns are left-handed, meaning all turns are made to the left. One of the main reason for this is that pilots sit on the left side of the airplane, and a Left-hand patterns improves their visibility of the airport and pattern. Right-handed patterns do exist, usually because of obstacles such as a mountain, or to reduce noise for local residents. The predetermined circuit helps traffic flow smoothly because all pilots know what to expect, and helps reduce the chance of a mid-air collision.
What is the answer to this question: Traffic patterns are usually flown at what altitude above ground level?
****
So... 800 or 1,000 ft


Article: According to statute, Qing society was divided into relatively closed estates, of which in most general terms there were five. Apart from the estates of the officials, the comparatively minuscule aristocracy, and the degree-holding literati, there also existed a major division among ordinary Chinese between commoners and people with inferior status. They were divided into two categories: one of them, the good "commoner" people, the other "mean" people. The majority of the population belonged to the first category and were described as liangmin, a legal term meaning good people, as opposed to jianmin meaning the mean (or ignoble) people. Qing law explicitly stated that the traditional four occupational groups of scholars, farmers, artisans and merchants were "good", or having a status of commoners. On the other hand, slaves or bondservants, entertainers (including prostitutes and actors), and those low-level employees of government officials were the "mean people". Mean people were considered legally inferior to commoners and suffered unequal treatments, forbidden to take the imperial examination.

Question: What was the legal term for commoner?
Ans:
liangmin
