Explanation:

The theory of implicit powers has its origin in the US Supreme Court, in the year 1819, in the preceding Mc CulloCh v. Maryland. According to theory, the Constitution, by granting a function to a particular institution, also implicitly confers the necessary means for the achievement of the activities of that institution. Thus, we can conclude that the correct answer to your question is:

all cities have a governor

all cities are in states or provnies then country

all cities have people

some are rich

some are poor

some are average
