Problem: Please answer a question about the following article about Samurai:
Despite the rampant romanticism of the 20th century, samurai could be disloyal and treacherous (e.g., Akechi Mitsuhide), cowardly, brave, or overly loyal (e.g., Kusunoki Masashige). Samurai were usually loyal to their immediate superiors, who in turn allied themselves with higher lords. These loyalties to the higher lords often shifted; for example, the high lords allied under Toyotomi Hideyoshi (豊臣秀吉) were served by loyal samurai, but the feudal lords under them could shift their support to Tokugawa, taking their samurai with them. There were, however, also notable instances where samurai would be disloyal to their lord or daimyo, when loyalty to the Emperor was seen to have supremacy.
Some feudal lords shifted loyalties from Toyotomi to whom?
A: Tokugawa
Problem: Please answer a question about the following article about Electric motor:
A common application of a torque motor would be the supply- and take-up reel motors in a tape drive. In this application, driven from a low voltage, the characteristics of these motors allow a relatively constant light tension to be applied to the tape whether or not the capstan is feeding tape past the tape heads. Driven from a higher voltage, (and so delivering a higher torque), the torque motors can also achieve fast-forward and rewind operation without requiring any additional mechanics such as gears or clutches. In the computer gaming world, torque motors are used in force feedback steering wheels.
In a tape drive, what is not needed if a torque motor is used?
A: gears or clutches
Problem: Please answer a question about the following article about History of India:
Along with the desire for independence, tensions between Hindus and Muslims had also been developing over the years. The Muslims had always been a minority within the subcontinent, and the prospect of an exclusively Hindu government made them wary of independence; they were as inclined to mistrust Hindu rule as they were to resist the foreign Raj, although Gandhi called for unity between the two groups in an astonishing display of leadership. The British, extremely weakened by the Second World War, promised that they would leave and participated in the formation of an interim government. The British Indian territories gained independence in 1947, after being partitioned into the Union of India and Dominion of Pakistan. Following the controversial division of pre-partition Punjab and Bengal, rioting broke out between Sikhs, Hindus and Muslims in these provinces and spread to several other parts of India, leaving some 500,000 dead. Also, this period saw one of the largest mass migrations ever recorded in modern history, with a total of 12 million Hindus, Sikhs and Muslims moving between the newly created nations of India and Pakistan (which gained independence on 15 and 14 August 1947 respectively). In 1971, Bangladesh, formerly East Pakistan and East Bengal, seceded from Pakistan.
What did the British form in preparation to leaving India?
A: interim government

The Thames was once a much broader, shallower river with extensive marshlands; at high tide, its shores reached five times their present width.
What was the population density of Greater London in 2001?
A:
4,542 inhabitants per square kilometre (11,760/sq mi)
