Example input: There are a million times more viruses on the planet than stars in the universe. Viruses also harbor the majority of genetic diversity on Earth. Scientists are finding evidence of viruses as a planetary force, influencing the global climate and geochemical cycles. They have also profoundly shaped the evolution of their hosts. The human genome, for example, contains 100,000 segments of virus DNA.
Example output: How many segments of virus DNA does the human genome contain?
Example explanation: The paragraph states the number of segments of virus DNA does the human genome contain, hence the question asked above is appropriate.
Q: Jacksonville, like most large cities in the United States, suffered from negative effects of rapid urban sprawl after World War II. The construction of highways led residents to move to newer housing in the suburbs. After World War II, the government of the city of Jacksonville began to increase spending to fund new public building projects in the boom that occurred after the war. Mayor W. Haydon Burns' Jacksonville Story resulted in the construction of a new city hall, civic auditorium, public library and other projects that created a dynamic sense of civic pride. However, the development of suburbs and a subsequent wave of middle class 'white flight' left Jacksonville with a much poorer population than before. The city's most populous ethnic group, non-Hispanic white, declined from 75.8% in 1970 to 55.1% by 2010.
A:
What drove residents to quieter suburban housing?
