P: Mantua is the ancestral city where the male line of the Gonzaga dynasty ruled, first as marquesses, then after 1540 as dukes, in vassalage to the Holy Roman Empire. Monferrato was a duchy since 1574 on the eastern side of Piedmont, and an Imperial fief since the eleventh or twelfth century. The Gonzagas had enlarged their realm with Monferrato after receiving it in dowry from the wife of duke Frederick II Gonzaga. On 22 September 1612, Francis IV, Duke of Mantua and Monferrato died at the age of 26. His death occurred only a couple of months after the death of his father Vincent I, Duke of Mantua. He left only a three-year-old daughter, Maria of Mantua. Francis IV also had two younger brothers who, both being cardinals, could not marry and were thus ineligible to succeed to Mantua's throne. Nonetheless, Francis' two brothers, Ferdinando I and Vincenzo II , eventually did become Dukes of Mantua. Despite marrying, following the resignation of Ferdinando and the expulsion of Vincenzo from the Sacred College of Cardinals, neither produced any legitimate children. A crisis erupted when Vincenzo II died on 26 December 1627 at the age of 33, the same day that his niece Maria Gonzaga's marriage with Charles de Nevers was celebrated. Nevers was the eldest son and heir of Charles, Duke of Nevers, Rethel and Mayenne. Moreover, he was the head of the cadet branch of the House of Gonzaga, and after Vincenzo II, heir male of the Duchy of Mantua.
Answer this: How many children did Ferdinando I and Vincenzo II produce?

A: 0

P: The telecoms sector increased in value from Dh25.6 billion ($3.3 billion) in 2006 to Dh33.3 billion ($4.2 billion) in 2007. With a workforce of some 41,000 employees, the sector contributes 7% to annual GDP and is one of the countrys leading recipients of foreign direct investment (FDI). Under the development plan, the sector should employ 125,000 people by 2012 and contribute 10% of GDP. With the penetration rates of 69.4% from mobile phones and 8.95% for fixed lines, the Moroccan telecoms industry is set to continue to grow. The call centre industry partially as a result of offshore initiatives, such as Casanearshore and Rabat Technoplis will continue to expand. However, the worldwide call centre industry is highly competitive and education is the key to success if Morocco truly intends to become a leading international player in this industry.
Answer this: How many examples of the call centre industry are provided?

A: 2

P: Within days of Boleslaw's murder, Casimir III of Poland invaded the principality to save Polish merchants and Catholic residents from attacks in Lviv. In June 1340, Casimir returned with a larger army. After four weeks he reached an agreement with local nobles and their leader Dmytro Dedko: in return for their services, local nobles would enjoy protection from the Polish king. However, the agreement was short-lived. The data is sparse, but it seems that Galicia-Volhynia was divided between the Lithuanians and local nobles . During the winter 1340-1341, the Golden Horde attacked Poland and reached Lublin as a result of diminished tribute from the principality to the Mongol khan. The raid weakened Polish influence in the principality. Eufemija, Boleslaw's widow, was drowned in the Vistula in winter 1342 to keep her out of the succession disputes. Detko, who managed to play Poles, Lithuanians, and Mongols against each other, disappeared from written sources in 1344. The same year direct conflict between Poland and Lithuania renewed, but soon a peace treaty was signed: Volhynia was assigned to Liubartas and Galicia to Casimir.
Answer this: What happened second: Golden Horde attacked Poland or Volhynia was assigned to Liubartas?

A:
Volhynia was assigned to Liubartas
