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.
