The motive that best completes the list is:
European countries wanted to spread their culture and civilize Africa and Asia.
This motive is often referred to as the "civilizing mission" or "white man's burden" and was a common justification used by European imperial powers to justify their expansion into Africa and Asia during the late 19th and early 20th centuries. The idea was that Europeans had a moral obligation to bring their superior culture and civilization to the "uncivilized" peoples of the world. While this motive was often couched in benevolent terms, the reality was that European expansionism had significant negative impacts on the cultures, economies, and political systems of the regions they colonized.
