question:
Passage: In 2011, it became apparent that the bail-out would be insufficient and a second bail-out amounting to €130 billion ($173 billion) was agreed in 2012, subject to strict conditions, including financial reforms and further austerity measures. As part of the deal, there was to be a 53% reduction in the Greek debt burden to private creditors and any profits made by Eurozone central banks on their holdings of Greek debt are to be repatriated back to Greece. Greece achieved a primary government budget surplus in 2013. In April 2014, Greece returned to the global bond market as it successfully sold €3 billion worth of five-year government bonds at a yield of 4.95%. Greece returned to growth after six years of economic decline in the second quarter of 2014, and was the Eurozone's fastest-growing economy in the third quarter. Question: In what year did Greece realize a budget surplus?
answer:
2013


question:
Passage: Other cities with a concentration of secular Gothic include Bruges and Siena. Most surviving small secular buildings are relatively plain and straightforward; most windows are flat-topped with mullions, with pointed arches and vaulted ceilings often only found at a few focal points. The country-houses of the nobility were slow to abandon the appearance of being a castle, even in parts of Europe, like England, where defence had ceased to be a real concern. The living and working parts of many monastic buildings survive, for example at Mont Saint-Michel. Question: What style are most windows on secular Gothic structures?
answer:
flat-topped with mullions


question:
Passage: Luther secretly returned to Wittenberg on 6 March 1522. He wrote to the Elector: "During my absence, Satan has entered my sheepfold, and committed ravages which I cannot repair by writing, but only by my personal presence and living word." For eight days in Lent, beginning on Invocavit Sunday, 9 March, Luther preached eight sermons, which became known as the "Invocavit Sermons". In these sermons, he hammered home the primacy of core Christian values such as love, patience, charity, and freedom, and reminded the citizens to trust God's word rather than violence to bring about necessary change. Question: When did Luther return to Wittenberg?
answer:

6 March 1522
