Input: Article: 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.

Now answer this question: What did Greece sign to apply to join the eurozone?

Output: Maastricht Treaty

Crop over began in 1688, and featured singing, dancing and accompaniment by shak-shak, banjo, triangle, fiddle, guitar, bottles filled with water and bones. Other traditions included climbing a greased pole, feasting and drinking competitions. Originally signaling the end of the yearly cane harvest, it evolved into a national festival.
