huinventors1-8, Exercise 1: Why they left Model answer (any three): 1. The upheavals of 1919 and the violent reaction that followed drove some intellectuals out. 2. The 1920 law limiting university admission by group, aimed in practice at Jewish students, pushed some to study abroad, especially in Germany. 3. The rise of the Nazi regime in the 1930s forced those who had settled in Germany to move again, to Britain and the United States. 4. Universities and laboratories abroad offered posts, resources and colleagues that were hard to find at home. There was no single cause. Details should be checked.
