Explanation:

False

Explanation:

According to Walter Christaller's central place theory, it is FALSE that smaller cities can provide a more diverse array of services than larger cities.

This is evident in the fact that Walter Christaller, a German Geographer in 1933, brought the idea of central-place theory in his book titled "Central Places in Southern Germany."

Walter Christaller explained that larger cities or higher-order places produce more goods and services than other places, while the smaller cities or lower-order places have little market areas, hence, they produce goods and services that are purchased more frequently than higher-order goods and services.
