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.
Civilization is the establishment of culture and a system of government in a society. And due to such privilege the society enjoys it thrives and grow larger and there would be a population growth and also poverty would be present and thus slums are created due to such growth but the system didn't change to cope up with the change happening.
President Franklin D. Roosevelt laid his plans aimed to end the Great Depression through The New Deal program. The New Deal is set of laws which will be passed for the first 100 days of his term. This does not include the Fair Labor Standards Act.
John F. Kennedy had sent the civil rights bill so John F. Kennedy is the correct answer
