What are two obvious ideas in the advertisement that reflect European views about race and the nonwhite people living in European colonies? What do these ideas imply about European colonialism and the belief in white superiority? How do these and other ideas in the advertisement use racism to promote imperialism?

Hello. You did not post the announcements that the question refers to, but I can help you, since the announcements that reflected European views at the time of imperialism, generally displayed obvious ideas about the purity and superiority of the white man and the idea that colonies are dirty places without civilization.

The idea of purity and superiority is related to the idea of the "white man's burden", which was a concept that stated that it was a duty (given by God) to Europeans to "clean up", take Christianity and dominate regions with inferior people , in this case, non-white people who lived in other countries, who were considered unclean and therefore needed to be purified by whites.

In this way, Europeans used a strong racist bias to dominate and enslave peoples of other ethnicities, promoting imperialism while claiming that this was the role that God had assigned to whites in this world.
