Question

which contributed to the spread of domestic terrorism? colonial groups seeking independence from imperialistic powers civilian unrest due to government - enforced restrictions declining economies in various developing countries improved methods for recruiting new members

Explanation:

Civilian unrest due to government - enforced restrictions can create an environment where some individuals may turn to domestic terrorism as a form of protest or to achieve their goals. Colonial groups seeking independence from imperialistic powers usually engage in struggles against external powers rather than domestic terrorism in the context of the home - country. Declining economies in developing countries may cause social problems but not directly contribute to domestic terrorism. Improved recruitment methods are a consequence or a tool for terrorist groups rather than a root cause for the spread of domestic terrorism.

Answer:

civilian unrest due to government - enforced restrictions
