Question: What country did Commandino study in? Passage:Born in Urbino, he studied at Padua and at Ferrara, where he received his doctorate in medicine.

He also translated the works of Aristarchus of Samos (On the sizes and distances of the Sun and the Moon), Pappus of Alexandria (Mathematical collection), Hero of Alexandria (Pneumatics), Ptolemy of Alexandria (Planisphere and Analemma), Apollonius of Perga (Conics) and Euclid of Alexandria (Elements).

Question: Who was the manager of Manchester United when Duncan Edwards died as a result of the Munich air disaster? Passage:The most famous former resident of the Priory Estate is Duncan Edwards, who was born two miles away at Holly Hall but moved to 31 Elm Road as a small child and went on to play 18 times for England as well as winning two Football League championships with Manchester United before he died in 1958 at the age of 21 from injuries sustained in the Munich air disaster. As a child, he had attended Priory Primary School and then Wolverhampton Street School. The school is most famous for being the former school (1941 to 1948) of the late Duncan Edwards, the former Manchester United and England footballer. He died aged 21 as a result of the Munich air disaster in 1958. After his death, a stained glass window was dedicated to Edwards at St Francis parish church at the junction of Laurel Road and Poplar Crescent. The church was founded during 1931 and originally based at Priory Hall before the church building on the newly developed housing estate was opened on 10 May 1932.

Question: Where was the person who granted Serbia autonomy born? Passage:The Ottoman Bosnian leadership led by Husein Gradaščević were outraged when Sultan Mahmud II granted Serbia autonomy and subsequently six districts from the Bosnia Eyalet with the Treaty of Adrianople. Husein Gradaščević had already begun to support the cause of the fallen Janissary after the Auspicious Incident and would not allow Mahmud II to further disintegrate Bosnian society. Instead of negotiating with Husein Gradaščević, the Grand Vizier Reşid Mehmed Pasha (already engaged in an aggressive campaign against Albanian pashas and beys) mobilized his Ottoman army towards Travnik. Disappointed by Reşid Pasha's move, Gradaščević marched forward with an army of 52,000 into Priština, and later fought and defeated Reşid Pasha at Štimlje. A Bosnian delegation reached the Grand Vizier's camp in Skopje in November of that year. The Grand Vizier promised this delegation that he would insist to the Sultan that he accept the Bosniak demands. His true intentions, however, were manifested by early December when his cannons attacked Bosnian units stationed on the outskirts of Novi Pazar. Reşid Mehmed Pasha later began an aggressive campaign into Bosnia with the assistance of the renegade kapetan Ali-paša Rizvanbegović and defeated the entire army of Bosnia Eyalet led by Husein Gradaščević outside the town of Stup.
