Question: How many countries border the body of water on the coast of which Hommaire coordinated the construction of a lighthouse? Passage:After attending school in Altkirch and Dijon, Hommaire graduated as an engineer at the École des Mines in Saint-Étienne in 1833. There he met Adèle Hériot whom he married in 1834.

question:
Question: How many years did the person who possibly encouraged Eumenes to revolt reign? Passage:Although nominally under Seleucid control, Pergamon under Philetaerus enjoyed considerable autonomy. However, upon his succession, Eumenes, perhaps with the encouragement of Ptolemy II, who was at war with the Seleucids, revolted, defeating the Seleucid king Antiochus I near the Lydian capital of Sardis in 261 BC. He was thus able to free Pergamon, and greatly increase the territories under his control. In his new possessions, he established garrison posts in the north at the foot of Mount Ida called Philetaireia after his adoptive father, and in the east, northeast of Thyatira near the sources of the river Lycus, called Attaleia after his grandfather, and he extended his control south of the river Caïcus to the Gulf of Cyme as well. Demonstrating his independence, he began to strike coins with the portrait of Philetaerus, while his predecessor had still depicted Seleucus I Nicator.

question:
Question: In 1970 which university had more students, Princeton University or American University in Cairo? Passage:Beinin was raised as a Zionist in an American Jewish family. On graduating from high school, he spent six months working on a kibbutz, where he met his future wife. He studied Arabic at university, and received his B.A. from Princeton University in 1970. He spent the summer of 1969 studying Arabic at the American University in Cairo. Intending to move to Israel permanently, he joined other members of Hashomer Hatzair in living and working at Kibbutz Lahav. There, on encountering attitudes that struck him as being contemptuous of Palestinians, he gradually became disenchanted with his early ideals. He returned to the United States in 1973, and took his M.A. from Harvard University in 1974, and, after working in auto plants in Detroit, obtained his A.M.L.S. and Ph.D. from the University of Michigan in 1978 and 1982, respectively. He has also studied at the Hebrew University of Jerusalem.
