which of the following choices was not a factor that inspired imperialism?
religious fervor and cultural superiority
the need for raw materials for industrialization
nationalism and desire for power
the need for cheap labor for industrialization

I think it would be religious fervor and cultural superiority.   During the imperialist era, many colonies were created because of these two reasons. To take an example, Spain had started exploring the New World because they wish to expand their territory and to Christianize the natives whom they referred to as barbarians.
