But the important question is what natural power creates a big city center. We are, after all, in an age of electronic communication; our big shopping areas have moved out of city centers, and our living areas moved out of them long ago. Yet some force causes offices and service industries related to them to gather in London or New York or Tokyo. This suggests that far from the problems of a crowded environment forcing companies and people to move out, there is a critical (重大的) size beyond which more companies are attracted to move in. Nobody seems to know why, yet the answer is important to the way traffic jam is dealt with.

C．The great number of cars in the city centers. D．The bad road conditions.
