Problem: Please answer a question about the following article about War on Terror:
Support for the U.S. cooled when America made clear its determination to invade Iraq in late 2002. Even so, many of the "coalition of the willing" countries that unconditionally supported the U.S.-led military action have sent troops to Afghanistan, particular neighboring Pakistan, which has disowned its earlier support for the Taliban and contributed tens of thousands of soldiers to the conflict. Pakistan was also engaged in the War in North-West Pakistan (Waziristan War). Supported by U.S. intelligence, Pakistan was attempting to remove the Taliban insurgency and al-Qaeda element from the northern tribal areas.
How many soldiers did Pakistan contribute to fight the Taliban?
A: tens of thousands

Problem: Please answer a question about the following article about Warsaw Pact:
The Warsaw Pact (formally, the Treaty of Friendship, Co-operation, and Mutual Assistance, sometimes, informally WarPac, akin in format to NATO) was a collective defense treaty among Soviet Union and seven Soviet satellite states in Central and Eastern Europe in existence during the Cold War. The Warsaw Pact was the military complement to the Council for Mutual Economic Assistance (CoMEcon), the regional economic organization for the communist states of Central and Eastern Europe. The Warsaw Pact was created in reaction to the integration of West Germany into NATO in 1955 per the Paris Pacts of 1954, but it is also considered to have been motivated by Soviet desires to maintain control over military forces in Central and Eastern Europe.
The acceptance of which country into NATO prompted the formation of the Warsaw Pact?
A: West Germany
Problem: Please answer a question about the following article about Beer:
Cask-conditioned ales (or cask ales) are unfiltered and unpasteurised beers. These beers are termed "real ale" by the CAMRA organisation. Typically, when a cask arrives in a pub, it is placed horizontally on a frame called a "stillage" which is designed to hold it steady and at the right angle, and then allowed to cool to cellar temperature (typically between 11–13 °C or 52–55 °F), before being tapped and vented—a tap is driven through a (usually rubber) bung at the bottom of one end, and a hard spile or other implement is used to open a hole in the side of the cask, which is now uppermost. The act of stillaging and then venting a beer in this manner typically disturbs all the sediment, so it must be left for a suitable period to "drop" (clear) again, as well as to fully condition—this period can take anywhere from several hours to several days. At this point the beer is ready to sell, either being pulled through a beer line with a hand pump, or simply being "gravity-fed" directly into the glass.
How long does it take for sediment to settle and clear after a cask ale has been tapped?
A:
from several hours to several days
