Question: Which countries made up the group that invaded Yugoslavia? Passage:On 6April 1941, Yugoslavia was invaded from all sides by the Axis powers, led by German forces. Stojanovic 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 Stojanovic returned to Prijedor. The Royal Yugoslav Army capitulated on 17April, 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 Ustase led by Ante Pavelic. 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: How large is the city where Rollo May was born? Passage:May was born in Ada, Ohio, on April 21, 1909. He experienced a difficult childhood when his parents divorced and his sister was diagnosed with schizophrenia. He was the first son of a family with six children. His mother often left the children to care for themselves, and with his sister suffering from schizophrenia, he bore a great deal of responsibility. His educational career took him to Michigan State University, where he pursued a major in English, but he was expelled due to his involvement in a radical student magazine. After being asked to leave, he attended Oberlin College and received a bachelor's degree in English. He later spent three years teaching in Greece at Anatolia College. During this time, he studied with doctor and psychotherapist Alfred Adler, with whom his later work shares theoretical similarities. He became ordained as a minister shortly after coming back to the United States, but left the ministry after several years to pursue a degree in psychology. He was diagnosed with tuberculosis in 1942 and spent 18 months in a sanatorium. He later attended Union Theological Seminary for a BD during 1938, and finally to Teachers College, Columbia University for a PhD in clinical psychology in 1949. May was a founder and faculty member of Saybrook Graduate School and Research Center in San Francisco.

Question: What are the names of the members of the heel team that defeated the Godwinns? Passage:In 1996, Canterbury was reunited with Knight, who had been renamed Phineas I. Godwinn. The duo were portrayed as being cousins (later brothers) and were collectively known as "The Godwinns". The two were faces and were managed by Hillbilly Jim. They began to feud with the Body Donnas with Phineas having a crush on Sunny and signed her as their manager. They would beat the Body Donnas for the WWF Tag Team Championships. Eventually Sunny turned on them costing them their titles. The Godwinns feuded with the now heel Smoking Gunns, in losing efforts. In 1997, the Godwinns began a heel turn dropping Hillbilly Jim as a manager and picking up Uncle Cletus. The Godwinns quickly won the tag titles a second time from The Headbangers and began a heated feud with the Legion of Doom, which saw the team attempt to break Road Warrior Hawk's neck. They eventually dropped the titles to LOD in a match on WWF Monday Night Raw that had LOD's career on the line. Soon after that match they attacked and fired Cletus.
