Q: 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 was most famous for his central role as translator of works of ancient mathematicians. In this, his sources were primarily written in Greek and secondarily in Arabic, while his translations were primarily in Latin and secondarily in Italian. He was responsible for the publication of many treatises of Archimedes. 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). Among his pupils was Guidobaldo del Monte and Bernardino Baldi. Commandino maintained a correspondence with the astronomer Francesco Maurolico. The proposition known as Commandino's theorem first appears in his work on centers of gravity.

Q: Question: Who has played for more teams the original striker for FC Porto at the beginning of 2003-04 season or the player that replaced him? Passage:The 2003–04 season began with another 1–0 win over União de Leiria, which gave the club its 13th Supertaça. Weeks later, Porto failed to repeat this result in the 2003 UEFA Super Cup, losing 1–0 to Milan. The departure of striker Hélder Postiga was compensated by the signing of South Africa's Benni McCarthy, whose 20 league goals helped Porto in its league title defence and crowned him the competition's top scorer. Mourinho entered the 2003–04 UEFA Champions League with confidence to his team. Porto finished second in its group, losing only once to Real Madrid, and advanced to a round-of-16 meeting with Manchester United. Porto scored on the 90th minute of the second leg at Old Trafford to draw 1–1 and advance to the quarter-finals with a 3–2 aggregate win. The team then overcame Lyon and Deportivo La Coruña and reached the Champions League final, where it defeated Monaco 3–0 to lift the club's second European Champion Clubs' Cup. A 2–1 loss to Benfica in the Taça de Portugal final, held 10 days before, prevented another treble-winning season.
