Passage: With his health continuing to deteriorate, the Black Prince returned to England in January 1371, whereby now his father Edward III was elderly and also in poor health. The prince's illness was debilitating, and he died on 8 June 1376. Edward III died the following year on 21 June 1377; he was succeeded by the Black Prince's second son Richard II , who was still a child. The treaty at Brétigny left Edward III and England with enlarged holdings in France; however, a small professional French army under the leadership of du Guesclin pushed the English back and, by the time of Charles V's death in 1380, the English only held Calais and a few other coastal cities. It was usual to appoint a regent in the case of a child monarch, but no regent was appointed for Richard II, who nominally exercised the power of kingship from the date of his accession in 1377. However, between 1377 and 1380, actual power was in the hands of a series of councils. The political community preferred this to a regency led by the king's uncle, John of Gaunt, although Gaunt remained highly influential. Richard faced many challenges during his reign, including the Peasants' Revolt led by Wat Tyler in 1381 and an Anglo-Scottish war in 1384-1385. His attempts to raise taxes to pay for his Scottish adventure and for the protection of Calais against the French made him increasingly unpopular. 
Question: How many years did Edward III outlive his son? 
Answer type: Number

Passage: The Ravens were facing the Tampa Bay Buccaneers, a team with an identical 7-3 record. However, the Ravens were considered favorites going into the game, given that they had never lost at home during the season, and all Tampa Bay wins were against teams with losing records. Still, they did not take this one lightly. After a scoreless first quarter, the Ravens scored first with a field goal. Tampa Bay later tied it, but Baltimore scored two touchdowns, including one on a 65-yard pass from Todd Heap, to have a 17-3 halftime lead. During a scoreless third quarter, a would be long TD-run from Ray Rice was negated by a controversial call of a penalty on Anquan Boldin. Though the Ravens would never score anymore in the game, they managed to hold off Tampa Bay and allow just one touchdown, enough to prevent their lead from being blown. 
Question: How many points were scored in the first half? 
Answer type: Number 
20.

Passage: While Polish-Lithuanian army concentrated in Podolia, in deep south of the enormous Commonwealth, on August 19, 1621, a Swedish army landed near Pärnu , carried by a fleet of 148 vessels . Gustav Adolf had 14,700 infantry, 3,150 cavalry and 375 cannons. Swedes immediately marched towards Riga, and besieged it on 29 August. The capital of Livonia was defended by a garrison of 300 soldiers, plus 3,700 armed residents. Lithuanian Field Hetman Krzysztof Radziwiłł had only 1,500 soldiers at his disposal, as most units were in Podolia and Red Ruthenia. Riga capitulated on September 25, after a month siege and three assaults. On October 2, Swedes captured the fortress of Dunamunde. The invaders, marching through marshes and forests to avoid Lithuanian cavalry, entered the Duchy of Courland and Semigallia, capturing its capital, Mitau without resistance. Swedes then tried to capture the fortress of Koknese, but failed to do so, after a skirmish with Lithuanian cavalry of Aleksander Gosiewski. In early January 1622, the Swedes captured Valmiera, together with several smaller Livonian castles. Meanwhile, the forces under Hetman Radziwill grew to 3 000, which enabled the Lithuanians to seal several Swedish garrisons. On January 7, Radziwiłł recaptured Mitau, but for lack of artillery, he failed to seize its castle, whose garrison did not capitulate until July 6. A few weeks later, in late July 1622, main Swedish forces reached Mittau, and a prolonged battle ensued. Since the battle turned into a stalemate, on August 10, 1622, both sides signed a truce, which in 1623 was prolonged until March 1625. During the negotiations, envoys of Gustav Adolf suggested a Swedish-Lithuanian union.
