What do malcolm and donald bain decide to do in the wake of their fathers murder?

After they are told about their father's murder, Malcolm goes to England and Donalbain goes to Ireland. 

They fled Inverness without telling anyone, so they were suspected of committing their own father's murder.

Hope this helps!

Urban growth invariably feeds increased commercialization and industrialization. it requires continually expanding land areas. when urbanization rates are high, and countries do not have the institutional and managerial capacities or economic wherewithal to manage such rapid growths, they exert intense pressure on the types and nature of the resulting settlements. they contribute to the development of overcrowded slums and shanty towns without adequate essential services and necessary infrastructure.-by asit k. biswas and cecilia tortajada
