Article: London's largest industry is finance, and its financial exports make it a large contributor to the UK's balance of payments. Around 325,000 people were employed in financial services in London until mid-2007. London has over 480 overseas banks, more than any other city in the world. Over 85 percent (3.2 million) of the employed population of greater London works in the services industries. Because of its prominent global role, London's economy had been affected by the Late-2000s financial crisis. However, by 2010 the City has recovered; put in place new regulatory powers, proceeded to regain lost ground and re-established London's economic dominance. The City of London is home to the Bank of England, London Stock Exchange, and Lloyd's of London insurance market.

Question: What is the UK's central bank known as?

Here is a question about this article: Humanism is a philosophical and ethical stance that emphasizes the value and agency of human beings, individually and collectively, and generally prefers critical thinking and evidence (rationalism, empiricism) over acceptance of dogma or superstition. The meaning of the term humanism has fluctuated according to the successive intellectual movements which have identified with it. Generally, however, humanism refers to a perspective that affirms some notion of human freedom and progress. In modern times, humanist movements are typically aligned with secularism, and today humanism typically refers to a non-theistic life stance centred on human agency and looking to science rather than revelation from a supernatural source to understand the world.
What is the answer to this question:  What can be credited for the changes in the definition of humanism? 
****
So... intellectual movements


The problem: Answer a question about this article:
DC commutating electric motors, if fitted with laminated pole pieces, become universal motors because they can also operate on AC; reversing the current in both stator and rotor does not reverse the motor. But the now-standard AC distribution frequencies of 50 and 60 Hz caused difficulties with inductive reactance and eddy current losses. Many railways chose low AC frequencies to overcome these problems. They must be converted from utility power by motor-generators or static inverters at the feeding substations or generated at dedicated traction powerstations.
How can low frequencies be obtained?
****
The answer: converted from utility power

Faced with the stripping of their powers, Wu Sangui, later joined by Geng Zhongming and by Shang Kexi's son Shang Zhixin, felt they had no choice but to revolt. The ensuing Revolt of the Three Feudatories lasted for eight years. Wu attempted, ultimately in vain, to fire the embers of south China Ming loyalty by restoring Ming customs, ordering that the resented queues be cut, and declaring himself emperor of a new dynasty. At the peak of the rebels' fortunes, they extended their control as far north as the Yangtze River, nearly establishing a divided China. Wu then hesitated to go further north, not being able to coordinate strategy with his allies, and Kangxi was able to unify his forces for a counterattack led by a new generation of Manchu generals. By 1681, the Qing government had established control over a ravaged southern China which took several decades to recover. Manchu Generals and Bannermen were initially put to shame by the better performance of the Han Chinese Green Standard Army, who fought better than them against the rebels and this was noted by Kangxi, leading him to task Generals Sun Sike, Wang Jinbao, and Zhao Liangdong to lead Green Standard Soldiers to crush the rebels. The Qing thought that Han Chinese were superior at battling other Han people and so used the Green Standard Army as the dominant and majority army in crushing the rebels instead of Bannermen. Similarly, in northwestern China against Wang Fuchen, the Qing used Han Chinese Green Standard Army soldiers and Han Chinese Generals such as Zhang Liangdong, Wang Jinbao, and Zhang Yong as the primary military forces. This choice was due to the rocky terrain, which favoured infantry troops over cavalry, to the desire to keep Bannermen in the reserves, and, again, to the belief that Han troops were better at fighting other Han people. These Han generals achieved victory over the rebels. Also due to the mountainous terrain, Sichuan and southern Shaanxi were also retaken by the Han Chinese Green Standard Army under Wang Jinbao and Zhao Liangdong in 1680, with Manchus only participating in dealing with logistics and provisions. 400,000 Green Standard Army soldiers and 150,000 Bannermen served on the Qing side during the war. 213 Han Chinese Banner companies, and 527 companies of Mongol and Manchu Banners were mobilized by the Qing during the revolt. 400,000 Green Standard Army soldiers were used against the Three Feudatories besides 200,000 Bannermen.

How long did the Revolt of the Three Feudatories last?
Answer: eight years


Rep. Christopher H. Smith (R-NJ), criticized the State Department investigation, saying the investigators were shown "Potemkin Villages" where residents had been intimidated into lying about the family-planning program. Dr. Nafis Sadik, former director of UNFPA said her agency had been pivotal in reversing China's coercive population control methods, but a 2005 report by Amnesty International and a separate report by the United States State Department found that coercive techniques were still regularly employed by the Chinese, casting doubt upon Sadik's statements.
Which NGO investigated the Chinese program in 2005?
Amnesty International
