Problem: Accounts of the use of leeches for the medically dubious practise of blood-letting have come from China around 30 AD, India around 200 AD, ancient Rome around 50 AD and later throughout Europe. In the 19th century medical demand for leeches was so high that some areas' stocks were exhausted and other regions imposed restrictions or bans on exports, and Hirudo medicinalis is treated as an endangered species by both IUCN and CITES. More recently leeches have been used to assist in microsurgery, and their saliva has provided anti-inflammatory compounds and several important anticoagulants, one of which also prevents tumors from spreading.
Where did leeches begin being used for blood-letting?

Answer: China

Q: What is a question about this article? If the question is unanswerable, say "unanswerable".
The majority of the province's population is Han Chinese, who are found scattered throughout the region with the exception of the far western areas. Thus, significant minorities of Tibetan, Yi, Qiang and Nakhi people reside in the western portion that are impacted by inclement weather and natural disasters, environmentally fragile, and impoverished. Sichuan's capital of Chengdu is home to a large community of Tibetans, with 30,000 permanent Tibetan residents and up to 200,000 Tibetan floating population. The Eastern Lipo, included with either the Yi or the Lisu people, as well as the A-Hmao, also are among the ethnic groups of the provinces.
What is one of the largest minorities in Chengdu?
A: Tibetan

Context and question: The first Sky television rights agreement was worth 304 million over five seasons. The next contract, negotiated to start from the 199798 season, rose to 670 million over four seasons. The third contract was a 1.024 billion deal with BSkyB for the three seasons from 200102 to 200304. The league brought in 320 million from the sale of its international rights for the three-year period from 200405 to 200607. It sold the rights itself on a territory-by-territory basis. Sky's monopoly was broken from August 2006 when Setanta Sports was awarded rights to show two out of the six packages of matches available. This occurred following an insistence by the European Commission that exclusive rights should not be sold to one television company. Sky and Setanta paid a total of 1.7 billion, a two-thirds increase which took many commentators by surprise as it had been widely assumed that the value of the rights had levelled off following many years of rapid growth. Setanta also hold rights to a live 3 pm match solely for Irish viewers. The BBC has retained the rights to show highlights for the same three seasons (on Match of the Day) for 171.6 million, a 63 per cent increase on the 105 million it paid for the previous three-year period. Sky and BT have agreed to jointly pay 84.3 million for delayed television rights to 242 games (that is the right to broadcast them in full on television and over the internet) in most cases for a period of 50 hours after 10 pm on matchday. Overseas television rights fetched 625 million, nearly double the previous contract. The total raised from these deals is more than 2.7 billion, giving Premier League clubs an average media income from league games of around 40 million-a-year from 2007 to 2010.
How much many did the Premier League make from selling its internation rights during 2004-07?
Answer: The league brought in 320 million from the sale of its international rights for the three-year period from 200405 to 200607

Question: Unlike in Westminster style legislatures or as with the Senate Majority Leader, the House Majority Leader's duties and prominence vary depending upon the style and power of the Speaker of the House. Typically, the Speaker does not participate in debate and rarely votes on the floor. In some cases, Majority Leaders have been more influential than the Speaker; notably Tom DeLay who was more prominent than Speaker Dennis Hastert. In addition, Speaker Newt Gingrich delegated to Dick Armey an unprecedented level of authority over scheduling legislation on the House floor.
Is there an answer to this question: Are snate majority leaders more influential than Speaker of the house??

Answer: Majority Leaders have been more influential than the Speaker

In Japan, 14 August is considered to be the day that the Pacific War ended. However, as Imperial Japan actually surrendered on 15 August, this day became known in the English-speaking countries as "V-J Day" (Victory in Japan). The formal Japanese Instrument of Surrender was signed on 2 September 1945, on the battleship USS Missouri, in Tokyo Bay. The surrender was accepted by General Douglas MacArthur as Supreme Commander for the Allied Powers, with representatives of several Allied nations, from a Japanese delegation led by Mamoru Shigemitsu and Yoshijiro Umezu.
If it is possible to answer this question, answer it for me (else, reply "unanswerable"): Who accepted the Japanese surrender?
Ah, so..
General Douglas MacArthur
