Task: Question Generation
Input (English): Background Paragraph: The Gaia hypothesis states that the biosphere is its own living organism. The hypothesis suggests that the Earth is self-regulating and tends to achieve a stable state, known as homeostasis . For example the composition of our atmosphere stays fairly consistent, providing the ideal conditions for life. When carbon dioxide levels increase in the atmosphere, plants grow more quickly. As their growth continues, they remove more carbon dioxide from the atmosphere. In this way, the amount of carbon dioxide stays fairly constant without human intervention. 
Story: Two friends had a sleepover. They spent most of the time online looking up stuff and talking about it. Bill looked up the Gaia hypothesis, while Frank read about the Flat Earth theory.
Output (English): Which friend read more about Earth being self-regulating?
