Passage: After their big road win in Washington, the Eagles hosted the winless Miami Dolphins at muddy Lincoln Financial Field and won 17-7. The offenses struggled in the first quarter, and the first points would actually come via special teams in the second quarter, when Ted Ginn Jr. returned a punt 87 yards to paydirt for Miami. Later in the quarter, McNabb, who had already thrown two interceptions, was hit as he threw, spraining his ankle. David Akers came on to make a 34-yard field goal, and McNabb left the game. A. J. Feeley was spun up to play quarterback, but threw an interception of his own on his first drive. In the third quarter, Correll Buckhalter took the ball in from eight yards out for the go-ahead touchdown, making it 10-7. Feeley, after some helpful runs from running back Brian Westbrook, connected with receiver Jason Avant to increase the lead. The defense played a strong second half, and Westbrook carried seven times on the final drive, which killed the final 6:40 of the game. Without McNabb, Andy Reid leaned hard on Westbrook, who shattered his career-high with 32 carries, while picking up 148 yards. McNabb's post-game x-rays were negative. The win marked the first time Philadelphia had won consecutive games all season, as well as allowing them to reach .500 and remain in the playoff hunt in the NFC.
Question: Who threw interceptions during the game?

Passage: After the Lithuanians were defeated in the Battle of Streva by the Teutonic Knights in 1348, Liubartas lost all territories except for eastern Volhynia with Lutsk to Casimir and his ally Louis I of Hungary . Liubartas' brothers Algirdas and Kestutis organized several expeditions to Poland and Red Ruthenia. Lithuanians allied themselves with Muscovy: Liubartas married an unnamed daughter of Konstantin of Rostov, a relative of Simeon of Moscow, and Algirdas married Uliana of Tver, sister-in-law of Simeon. In spring 1351, Lubartas was taken prisoner by Louis, but was released in summer after a truce was agreed upon with Kestutis. The deal fell through and more military attacks followed in 1352. Another truce, rather favorable to the Lithuanians, was signed in fall 1352: Lubartas received not only Volhynia and Podolia, but also Belz and Chem. However, already in 1353, Liubartas attacked again. Casimir responded by organizing a large campaign against the pagan Lithuanians with a special permission from Pope Innocent VI. After the campaign did not achieve the desired results, Casimir contemplated an alliance with the Lithuanians. In 1366, Casimir, allied with Siemowit III of Masovia and nephews of Liubartas, resumed the war. As Algirdas was involved in conflicts in the east and Kestutis fought with the Teutonic Knights, Liubartas had to defend alone and was defeated. In fall 1366, a treaty was signed: Liubartas retained only eastern Volhynia with Lutsk and became somewhat dependent on Poland . Casimir awarded his allies: Yuri, son of Karijotas, received Chem, his brother Alexander received Volodymyr-Volynskyi, and Yuri, son of Narimantas, continued to rule Belz.
Question: How many years did Liubartas retain Belz and Chelm for?
