Input: Consider Input: Passage: On 28 July 2012, Jin won the gold medal in the men's 10 m air pistol at the 2012 Summer Olympics. On 5 August, he won the gold medal in the 50m, becoming the first man to successfully defend the 50-metre pistol Olympic title. By doing so, Jin also became the first man to win the 10 metre air pistol and 50 metre pistol gold medals at the same Olympics, and one of the five shooters to win two individual gold medals at one Olympics, being the first man to have done so since Otto Olsen of Norway at the 1920 Summer Olympics. He is one of three shooters to have won three Olympic individual gold medals, along with Ralf Schumann of Germany and Kim Rhode of the United States. He became the first Korean athlete to win three individual Olympic gold medals, to win four (and five) individual Olympic medals, to defend an individual title in the Summer Olympics (while Sim Kwon-Ho won Olympic gold medals for Greco-Roman wrestling in 1996 and 2000, he won two different weight divisions), to win two individual gold medals at one Summer Olympic Games and to win an individual medal for one event at three consecutive Olympic Games (Kim Soo-Nyung won individual gold, silver and bronze medals respectively for archery in the 1988, 1992 and 2000 but these Olympics were non-consecutive).
 Link Information: none Question: What was Jin's score in the event where he won a gold medal on July 28, 2012?

Output: Answer: none


Input: Consider Input: Passage: Ten laps into the race, Michael Waltrip passed pole-sitter Jeff Gordon for the lead. On Lap 19, the caution flag was thrown after a multi-car accident. Waltrip continued leading until Lap 55, in which Dale Earnhardt Incorporated teammate Dale Earnhardt, Jr. After Bobby Hamilton, Jr. had an accident on Lap 70, Earnhardt led the race into pit road, but was pushed out by Gordon and Brian Vickers, and fell to fifteenth, giving Mike Wallace the lead entering Lap 74. Shepherd pitted on the following lap, and Morgan Shepherd took the lead. However, Shepherd would later pit, as Gordon regained the lead. Waltrip then retook the lead from Gordon on Lap 86, though Gordon then took the lead again 13 laps later. Ten laps later, Gordon pitted, and Waltrip was given the lead. On the ensuing lap, Earnhardt took the lead, though he later pitted, and Jimmy Spencer gained the lead. On Lap 113, Spencer lost the lead to Gordon when he pitted, who led the pit stops on Lap 139. Dave Blaney stayed out, and took the lead, though Ryan Newman gained first-place when Blaney went to pit road. Newman pitted on Lap 143, giving Tony Stewart the lead. With ten laps left in the race, Hendrick Motorsports teammates Jeff Gordon and Jimmie Johnson followed in third and fourth, respectively, behind Tony Stewart and Dale Earnhardt, Jr. Johnson then pushed Gordon past Stewart and Earnhardt, and Gordon subsequently won, his fourth of the season and second consecutive. The victory by Gordon made him the first driver since Cale Yarborough to win the Pepsi 400 from the pole. A version of the race's waning moments was included in the prologue of the video game , which involved Johnson pushing Gordon past Earnhardt.
 Link Information: Yarborough has been married to Betty Jo Thigpen since 1961 and they have three daughters Question: How many children did the man have who was was the last driver before Gordon to win the Pepsi 400 from the pole?

Output: Answer: three 


Input: Consider Input: Passage: The Duchy of Prussia was a duchy in the eastern part of Prussia from 1525–1701. In 1525 during the Protestant Reformation, the Grand Master of the Teutonic Knights, Albert of Hohenzollern, secularized the Prussian State of the Teutonic Order, becoming Albert, Duke in Prussia. His duchy, which had its capital in Königsberg (Kaliningrad), was established as a fief of the Crown of Poland, as had been Teutonic Prussia since the Second Peace of Thorn in October 1466. This treaty had ended the War of the Cities or Thirteen Years' War and provided for the Order's cession of its rights over the western half of its territories to the Polish crown, which became the province of Royal Prussia, while the remaining part of the Order's land became a fief of the Kingdom of Poland (1385–1569). In the 17th century King John II Casimir of Poland submitted Frederick William to regain Prussian suzerainty in return for supporting Poland against Sweden. On July 29, 1657, they signed the Treaty of Wehlau in Wehlau (Polish: Welawa; now Znamensk), whereby Frederick William renounced a previous Swedish-Prussian alliance and John Casimir recognised Frederick William's full sovereignty over the Duchy of Prussia. Full sovereignty was a necessary prerequisite for upgrading the Duchy to Kingdom of Prussia in 1701.

Question: What was the age difference between the 17th century Polish king and the person he helped regain Prussian in exchange for his support against Sweden?
