Teacher: Now, understand the problem? Solve this instance: Question: What country was the location of the castle that was exchanged for Dinaburg Castle? Passage 1:Traidenis, known for his devotion to paganism and anti-German attitude, was also successful in fighting with the Livonian Order. In 1270 he won the Battle of Karuse, fought on ice near Saaremaa, and killed Otto von Lutterberg, master of the Order. A new master, Andreas von Westfalen, sought a quick revenge, but was also killed by Traidenis. However, by 1272 the Order retaliated, attacking Semigalia and building Dinaburg Castle in 1273 on lands nominally controlled by Traidenis. Despite four siege engines used to throw stones, he was unable to capture the new fortress and had to retreat in 1278. In 1279 the order attacked Lithuanian lands, reaching as far as Kernavė, but on their way back they suffered a great defeat in the Battle of Aizkraukle. The Order's master, Ernst von Rassburg, became the third master to be killed by Traidenis. The defeat encouraged conquered Semigallians to rebel. The Semigalians, led by Nameisis, were now willing to acknowledge Lithuania's superiority and asked Traidenis for assistance. In 1281, Traidenis conquered Jersika Castle in the present-day Preiļi District, and was able to exchange it for Dinaburg Castle. However, Traidenis died soon afterwards, and assistance to Semigalians, exhausted by constant warfare, diminished. Traidenis is the first known Lithuanian duke to have died a natural death. All others before him were assassinated or killed in battle.
 Passage 2:Following their win over the Chargers, the Patriots flew to Orchard Park, New York for an AFC East duel with the Buffalo Bills. The Patriots grabbed the lead in the first quarter, with quarterback Tom Brady throwing two touchdown passes – a 14-yarder to wide receiver Wes Welker and a 1-yarder to tight end Rob Gronkowski. The Patriots added to their lead in the second quarter, with Brady connecting with Rob Gronkowski on a 26-yard touchdown pass. The Patriots lead was now 21-0 halfway through the second quarter. The Bills responded, with quarterback Ryan Fitzpatrick throwing an 11-yard touchdown pass to wide receiver Steve Johnson, followed by a 42-yard field goal by placekicker Ryan Lindell. The Bills narrowed the Patriots' lead in the third quarter, with a 3-yard touchdown pass from Fitzpatrick to tight end Scott Chandler. The Patriots increased their lead, with a 23-yard field goal by placekicker Stephen Gostkowski. The Bills tied the game in the fourth quarter, with a 1-yard touchdown run by running back Fred Jackson, then grabbed a 31–24 lead when cornerback Drayton Florence returned a Brady interception 27 yards for a touchdown. The Patriots tied the game, with a 6-yard touchdown pass from Brady to Welker. However, the Bills got the last possession, and after a touchdown that was ruled that Fred Jackson's knee hit the ground before he was in the endzone, the Bills killed clock by draining time and making the Patriots use timeouts. The Bills then won as Lindell nailed a 28-yard field goal as time expired, snapping the Patriots' 15-game winning streak against the Bills.
 Passage 3:After spending most of early 2010 off TV, Lethal returned on the March 29 episode of Impact! by approaching Hulk Hogan, reminiscing about their days as "The Mega Powers" (Hogan's old team with Randy Savage). Playing along with Lethal's antics, Hogan placed him in charge of the show for his one-week absence due to a business trip. After raising the ire of Hogan's business partner Eric Bischoff with his comedic booking ideas, Bischoff placed Lethal in a two-on-one handicap match against Beer Money, Inc.; Lethal, however, managed to win the match after surprising Robert Roode with a roll-up. On the May 3 episode of Impact!, Hogan gave Lethal Ric Flair's Hall of Fame ring that Abyss had won from him the previous week. When Lethal, now imitating Flair, was confronted by Flair himself, he claimed that he meant no disrespect and out of respect towards Flair, returned the ring to him. This, however, wasn't enough for Flair, who attacked Lethal along with A.J. Styles, Desmond Wolfe and Beer Money, Inc., before he was saved by Abyss, Team 3D and the TNA World Heavyweight Champion Rob Van Dam. At Sacrifice, Lethal came out during the TNA World Heavyweight Championship match between champion Rob Van Dam and challenger A.J. Styles, and locked Ric Flair in a Figure-four leglock in order to prevent him from interfering in the match. On the May 20 episode of Impact!, Lethal competed in his first match after dropping the Black Machismo gimmick, and teamed up with Rob Van Dam to defeat Beer Money, Inc. in a tag team match. After the match, Lethal brawled with Flair. At Slammiversary VIII, Lethal defeated Flair's protégé A.J. Styles in a singles match. After defeating Desmond Wolfe, another one of Flair's allies, on the June 17 episode of Impact!, Hogan granted him a match with Flair at Victory Road. On July 11 at Victory Road, Lethal defeated Flair with his own move, the figure-four leglock. On the August 5 episode of Impact!, Lethal faced Flair in a rematch, this time contested under Street Fight rules, with A.J. Styles, Kazarian, Robert Roode and James Storm of Flair's Fortune stable banned from ringside. Flair managed to win the match, after an interference from X Division Champion Douglas Williams, who would officially join Fortune the following week. On September 6, at the tapings of the September 16 episode of Impact!, Lethal defeated Williams to win the X Division Championship for the fourth time. On September 23, at a live event in New York City, Lethal lost the X Division Championship to Amazing Red. Lethal regained the title two days later at a live event in Rahway, New Jersey. At Bound for Glory, Lethal successfully defended the X Division Championship against Douglas Williams.
