Given the cities on the following list, what is the ratio of cities with high network connectivity to cities with low network connectivity?
boston / kinshasa / london / pyongyang / seoul.

High network connectivity - Boston, London, Seoul

Low network  connectivity - Kinshasa, Pyongyang

Explanation:

The cities that have high network connectivity are cities that have very well developed and modern infrastructure that enables them to be well connected with every other city and town in the closer and more distant areas. This kind of cities are typical for the developed nations, as they are nations that are open, have free flowing trade and communication, and the people are not restricted in their movement. On the other side, we have cities that have low network connectivity. Those are usually the cities in the countries that are not well developed, and the main reason why their network connectivity is low is because the infrastructure is very bad, the politics often are very restrictive for the economy and movement of people. These cities are usually only connected to the closest most important cities, and even that is done in a very bad manner which is everything but on satisfying level.
