Question: Passage: In the Treaty of Labiau on 20 November, Charles X Gustav of Sweden granted Frederick William of Brandenburg full sovereignty in the Duchy of Prussia in turn for a more active participation in the war. In the Treaty of Radnot on 6 December, Charles X Gustav promised to accept George II Rakoczi of Transylvania as king of Poland and Grand Duke of Lithuania in return for his entrance into the war. Rakoczi entered the war in January 1657, crossing into the commonwealth with a force of 25,000 Transylvanian-Wallachian-Moldavian men and 20,000 Cossacks who broke the Polish siege of Krakow before they met with Charles X Gustav, who had led a Swedish-Brandenburgian army southwards. The following month saw the Swedish-Brandenburg-Transylvanian-Romanian-Cossack forces play cat and mouse with the Polish-Lithuanian forces, moving about all of the commonwealth without any major engagements, except the capture of Brest by Charles X Gustav in May, and the sack of Warsaw by Rakoczi and Gustaf Otto Stenbock on 17 June. Due to internal conflicts within the Cossacks practically there was no participation of Cossack Hetmanate in that war. Worn out from previous campaigns and requesting Bohdan Khmelnytsky to break with Sweden, Alexis of Russia eventually signed the Truce of Vilna or Niemiez with the Polish-Lithuanian Commonwealth, and did not engage the Swedish army in any major battle throughout 1657 even though he still reinforced his armies in Livonia. On 18 June, a Swedish force defeated a Russian army of 8,000 men commanded by Matvey V. Sheremetev in the Battle of Walk at Walk . In early 1658, Sweden and Russia agreed on a truce, resulting in the Treaty of Valiesar and the Treaty of Kardis . The Russian war with Poland-Lithuania on the other hand resumed in 1658.
Question: What day was the Treaty of Labiau signed?

Question: Passage: The country's economic transformation was far from complete. Political and financial crises in 1997, shattered the Czech Republic's image as one of the most stable and prosperous of post-Communist states. Delays in enterprise restructuring and failure to develop a well-functioning capital market played major roles in Czech economic troubles, which culminated in a currency crisis in May. The formerly pegged currency was forced into a floating system as investors sold their Korunas faster than the government could buy them. This followed a worldwide trend to divest from developing countries that year. Investors also worried the republic's economic transformation was far from complete. Another complicating factor was the current account deficit, which reached nearly 8% of GDP. In response to the crisis, two austerity packages were introduced later in the spring , which cut government spending by 2.5% of GDP. Growth dropped to 0.3% in 1997, 2.3% in 1998, and 0.5% in 1999. The government established a restructuring agency in 1999 and launched a revitalization program - to spur the sale of firms to foreign companies. Key priorities included accelerating legislative convergence with EU norms, restructuring enterprises, and privatising banks and utilities. The economy, fueled by increased export growth and investment, was expected to recover by 2000.
Question: How many years after the government established a restructuring agency was export growth and investment expect to recover?

Answer: number

Question: Passage: The Genoese held the colony of Galata on the Golden Horn across from the city of Constantinople since 1261 as part of the Treaty of Nymphaeum, a trade agreement between the Byzantines and Genoese. However, the dilapidated state of the Byzantine Empire following the civil war of 1341-1347 was easily shown in the control of custom duties through the strategic straights of the Bosphorus. Even though Constantinople was the Imperial seat of power with its cultural and military center on the shores of the Bosphorus, only thirteen percent of custom dues passing through the strait were going to the Empire. The remaining 87 percent was collected by the Genoese from their colony of Galata. Genoa collected 200,000 hyperpyra from annual custom revenues from Galata, while Constantinople collected a mere 30,000. The Byzantine navy, a notable force in the Aegean during the reign of Andronikos III Palaiologos, was completely destroyed during the civil war. Thrace, the main imperial possession besides the Despotate of the Morea, was still recovering following the destruction of marauding Turkish mercenaries during the civil war. Byzantine trade was ruined and there were few other financial reserves for the Empire other than the duties and tariffs from the Bosphorus.
Question: Which year start the dilapidated state of the Byzantine Empire following the civil war ?
