Article: 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.

Question: How much would global sea levels rise if Greenland and Antartica's glaciers were to melt?
Ans: 70 m (230 ft)

Article: In an attempt to gain increased support from Polish nationalists and patriots, Napoleon termed the war the Second Polish Warthe First Polish War had been the Bar Confederation uprising by Polish nobles against Russia in 1768. Polish patriots wanted the Russian part of Poland to be joined with the Duchy of Warsaw and an independent Poland created.

The serfs later committed atrocities against French soldiers during France's retreat.

Ans: the Duchy of Warsaw

Article: In the early Western Han, a wealthy salt or iron industrialist, whether a semi-autonomous king or wealthy merchant, could boast funds that rivaled the imperial treasury and amass a peasant workforce of over a thousand. This kept many peasants away from their farms and denied the government a significant portion of its land tax revenue. To eliminate the influence of such private entrepreneurs, Emperor Wu nationalized the salt and iron industries in 117 BC and allowed many of the former industrialists to become officials administering the monopolies. By Eastern Han times, the central government monopolies were repealed in favor of production by commandery and county administrations, as well as private businessmen.

Question: In which year did Emperor Wu monopolize several industries?
Ans: 117 BC

Article: In the late 19th century, after the Berlin conference had ended, European empires sailed with their armies to the Horn of Africa. The imperial clouds wavering over Somalia alarmed the Dervish leader Mohammed Abdullah Hassan, who gathered Somali soldiers from across the Horn of Africa and began one of the longest anti-colonial wars ever. The Dervish State successfully repulsed the British empire four times and forced it to retreat to the coastal region. As a result of its successes against the British, the Dervish State received support from the Ottoman and German empires. The Turks also named Hassan Emir of the Somali nation, and the Germans promised to officially recognize any territories the Dervishes were to acquire. After a quarter of a century of holding the British at bay, the Dervishes were finally defeated in 1920, when Britain for the first time in Africa used airplanes to bomb the Dervish capital of Taleex. As a result of this bombardment, former Dervish territories were turned into a protectorate of Britain. Italy similarly faced the same opposition from Somali Sultans and armies and did not acquire full control of parts of modern Somalia until the Fascist era in late 1927. This occupation lasted till 1941 and was replaced by a British military administration.

Question: What states supported the Dervish State?
Ans:
the Ottoman and German empires
