Context: A wrestler can win by knockout (sometimes referred to as a referee stoppage) if they do not resort to submission holds, but stills pummels their opponent to the point that they are unconscious or are unable to intelligently defend themselves. To check for a knockout in this manner, a referee will wave their hand in front of the wrestler's face; if the wrestler does not react in any way, the referee will award the victory to the other wrestler. If all the active wrestlers in a match are down inside the ring at the same time, the referee will begin a count (usually ten seconds, twenty in Japan). If nobody rises to their feet by the end of the count, the match is ruled a draw. Any participant who stands up in time will end the count for everyone else. In a Last Man Standing match, this form of a knockout is the only way that the match can end, so the referee will count when one or more wrestlers are down, and one wrestler standing up before the 10-count doesn't stop the count for another wrestler who is still down.

Problem: Given the question: Extract the answer to the question from the following context. Question: What was the main result of Greece joining the eurozone? Context: Between 1832 and 2002 the currency of Greece was the drachma. After signing the Maastricht Treaty, Greece applied to join the eurozone. The two main convergence criteria were a maximum budget deficit of 3% of GDP and a declining public debt if it stood above 60% of GDP. Greece met the criteria as shown in its 1999 annual public account. On 1 January 2001, Greece joined the eurozone, with the adoption of the euro at the fixed exchange rate 340.75 to 1. However, in 2001 the euro only existed electronically, so the physical exchange from drachma to euro only took place on 1 January 2002. This was followed by a ten-year period for eligible exchange of drachma to euro, which ended on 1 March 2012.

The answer is:
exchange of drachma to euro

Problem: Given the question: Extract the answer to the question from the following context. Question: Which happened first: World War II or the Northland Center Hudson's rebranding? Context: After World War II Hudson's realized that the limited parking space at its downtown skyscraper would increasingly be a problem for its customers. The solution in 1954 was to open the Northland Center in nearby Southfield, just beyond the city limits. It was the largest suburban shopping center in the world, and quickly became the main shopping destination for northern and western Detroit, and for much of the suburbs. By 1961 the downtown skyscraper accounted for only half of Hudson's sales; it closed in 1986. The Northland Center Hudson's, rebranded Macy's in 2006 following acquisition by Federated Department Stores, was closed along with the remaining stores in the center in March 2015 due to the mall's high storefront vacancy, decaying infrastructure, and financial mismanagement.
