الصفحة 29 - Also, certain types of facilities require a certain size of population. For example, a symphony orchestra cannot exist in a small town. There is also the problem of size versus number. For example, many areas of the American Midwest have a large number of small colleges, each with 1,000 or 2,000 students. They all have libraries with more or less the same basic books. In a way, this large number of small colleges creates heterogeneity, but in another sense, a small number of large universities can...
