Question: Which countries made up the group that invaded Yugoslavia? Passage:On 6 April 1941, Yugoslavia was invaded from all sides by the Axis powers, led by German forces. Stojanović was assigned as a physician to an infantry battalion based in Banja Luka. For several days after the invasion this battalion moved toward Dalmatia, before it completely disintegrated without fighting the enemy, and Stojanović returned to Prijedor. The Royal Yugoslav Army capitulated on 17 April, and the Axis powers proceeded to dismember Yugoslavia. Almost all of modern-day Croatia, all of modern-day Bosnia-Herzegovina, and parts of modern-day Serbia were combined into a puppet state called the Independent State of Croatia (, NDH). It was an "Italian-German quasi-protectorate", which was controlled by the fascist Ustaše led by Ante Pavelić. One of its policies was to eliminate the ethnic Serb population of the NDH through mass killings, expulsions and forced assimilation, and many Serbs fled from the NDH to the German-occupied territory of Serbia.

Question: Are there any famous landmarks in Wilt Chamberlain's home town? Passage:Standing 6 ft 6 in, Meschery also was a highly talented basketball player. After graduating from St. Mary's, he was drafted by the Philadelphia Warriors as the 7th pick overall in the 1961 NBA draft. Meschery played alongside legend Wilt Chamberlain, to whom he later dedicated a poem. Meschery was the starting forward on the 1961-62 Philadelphia Warriors team in which Chamberlain scored 100 points. Meschery led the NBA in personal fouls in 1962 and he became the first foreign born player to play in an NBA All-Star Game when he played in the 1963 NBA All-Star Game. Chamberlain left the Warriors in 1965, returning to his home town Philadelphia, to play with the 76ers. The Warriors however, strengthened by the arrival of Rick Barry, made it to the 1967 NBA Finals, in which they lost to Chamberlain's 76ers. After his NBA Finals appearance, Meschery was selected by the NBA's Seattle SuperSonics during the 1967 NBA Expansion Draft.
