Task: Question Generation
Input (English): Background Paragraph: A mycorrhiza (Greek for "fungus roots") is a symbiotic association between a fungus and the roots of a plant. In a mycorrhizal association, the fungus may colonize the roots of a host plant by either growing directly into the root cells, or by growing around the root cells. This association provides the fungus with relatively constant and direct access to glucose, which the plant produces by photosynthesis. The mycelia of the fungi increase the surface area of the plant’s root system. The larger surface area improves water and mineral nutrient absorption from the soil. 
Story: Two mycologists were studying fungi. Jim studied more about wood eating mushrooms and gourmet mushrooms, while George decided to study more about mycorrhiza, and its benefits for humans.
Output (English): Which mycologist learned less about a symbiotic association between a fungus and the roots of a plant?
