Input: 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.
