Task: Question Generation
Input (English): Background Paragraph: Because of human activities, there is more carbon dioxide in the atmosphere today than in the past hundreds of thousands of years. Burning fossil fuels and has released great quantities of carbon dioxide into the atmosphere. Cutting forests and clearing land has also increased carbon dioxide into the atmosphere because these activities reduce the number of autotrophic organisms that use up carbon dioxide in photosynthesis. In addition, clearing often involves burning, which releases carbon dioxide that was previously stored in autotrophs. 
Story: Thanks to environmental initiatives, Quebec has grown a large number of forests recently that are densely populated with tall trees. At the same time, Ottawa has been cutting down large numbers of trees in their forests and clearing the land to make room for housing developments and new construction sites.
Output (English): Which city, Quebec or Ottawa, has increased their number of autotrophic organisms?
