Input: Consider Input: Passage: At the beginning of the 13th century, a Prussian trade route developed that crossed over an isthmus between two large lakes, the Sicienskie lake and the Zamkowe ("Castle lake"). A defensive wall was built at this spot, and later, a settlement was constructed there as well. The place is mentioned in a twelfth-century document regarding a battle in which Henry of Sandomierz was killed. Under the name "Wambresia" the town was mentioned in a 1251 Prussian Document issued at Chemza. Bishop Heidenreich of Bishopric of Chemno received the Chemno Land from the pope. The Polish duke Konrad I of Masovia turned possession of the settlement over to the bishop of Chemno. This created a problem because the Teutonic Knights were in control of the Chemno Land, and a dispute began between the Bishop of Chemno and the Knights. The Pope at the time, Innocent IV, was not keen to continue the dispute and installed the Bishop as the rightful ruler of the settlement. This disagreement was the first historical mention of the settlement. In 1251, a large church, St. Simon and Judah, was built in the city.

Input: Consider Input: Passage: Alydeed was owned and raced by David Willmot's Kinghaven Farms. Racing from a base at Woodbine Racetrack in Toronto, at age two his best performances were wins in an allowance race at Gulfstream Park in Florida, where he equalled the track record for 6.5 furlongs, and a win in Woodbine's Victoria Stakes. At age three, Alydeed won five of his ten starts. Near the end of April 1992, he was sent to Churchill Downs in Louisville, Kentucky where he won the Derby Trial. Based on his strong performance, his handlers decided to run him in the second leg of the U.S. Triple Crown series, the Preakness Stakes where he ran second to Pine Bluff. Back at Woodbine Racetrack, he won the Plate Trial Stakes then ran away from the field in the final quarter of a mile to win Canada's most prestigious race, the Queen's Plate. In the second leg of the Canadian Triple Crown series, the Prince of Wales Stakes, Alydeed was sent off as the prohibitive favorite at 1/9 odds. However, on a muddy Fort Erie Racetrack, Alydeed ran second to Benburb. Alydeed then elected to skip the third jewel of the Canadian Triple Crown opting for the Grade 1 Travers Stakes at Saratoga Race Course where he finished eighth to Thunder Rumble as the 8-5 favourite.

Input: Consider Input: Passage: Drupada, son of King Prishata, and Drona study together under the tutelage of Rishi Bhardwaja, Drona's father. They become great friends and Drupada assures Drona that once he becomes king, he will share half of his kingdom with Drona. While Drupada becomes a king after the death of his father, Drona lives a life of poverty. Drona approaches Drupada for help; Drupada, now conscious of the difference of status between them, refuses to acknowledge Drona's friendship and shuns Drona, calling him a beggar. Drona is later employed by Bhishma to train the Kuru princes. After the military education of the Kauravas and the Pandavas ends, as his gurudakshina, Drona asks the princes to defeat and capture Drupada. Firstly, all the Kauravas, along with Karna, attack Drupada, but Drupada defeats all of them. Then the Pandavas led by Arjuna defeat Drupada, binding him in ropes and bringing him to Drona. Drona sets Drupada free, but retains half of the kingdom that had been promised to him. Humiliated, Drupada seeks vengeance but he realizes that he cannot match Drona's might.

Years later, Draupadi married Arjuna and later in the Mahabharata war, Dhrishtadyumna beheaded Drona.
