How does the map of modern South Asia demonstrate the lingering effects of the British colonial rule PLEASE HELP

The main effect of the British Colonial Rule that can be still seen in the image is that prior to the British Colonization, South Asia was much more politically divided: there were many more kingdoms. The British unified the region, in order to make it easier to manage. Railroads were built all over the territory for this purpose, and to ease communication, and political administration was centralized.

on december 1, 1774, the continental association was created to boycott all contact with british goods. by reversing the economic sanctions placed on the colonists, the delegates hoped britain would repeal its intolerable acts.
