根据以下材料回答下面的题目:Academic MobilityScholars and students have always been great travelers. "Academic mobility" is now often stated as a fundamental necessity for economic and social progress in the world, 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.Mobility of this kind means also mobility of ideas, their transference across frontiers, their simultaneous impact upon many groups of people.

The vehicle which has made this possible has of course been the aero plane, making contact between scholars even in most distant places immediately feasible, and providing for the very rapid transmission of knowledge. Apart from the vehicle itself, it is fairly easy to identify the main factors which have brought about the recent explosion in academic movement. Some of these are purely quantitative and require no further mention: there are far more centers of leaming, and a far greater number of scholars and students.In addition, one must recognize the very considerable multiplication of disciplines, particularly in the sciences, which by widening the total area of advanced studies has produced an enormous number of specialists whose particular interests ale precisely defined. These people would work in some isolation if they were not able to keep in touch with similar isolated groups in other countries.It can be concluded from the passage that "academic mobility"__________
