Scholars and students have always been great travellers. The official case for "academic mobility" is now often stated in impressive terms as a fundamental necessity for economic and social progress in the world, and debated in the corridors of Europe, but it is certainly nothing new. Serious students were always ready to go abroad in search of the most stimulating teachers and the most famous academies; in search of the purest philosophy, the most effective medicine, the likeliest road to gold.

It must also have been reassuring to know that other people in other parts of the world were about to make the same discovery or were t
A. was a way of spreading ideas
B. broke down political barriers
C. led to economic progress
D. made new ideas less schooling
