Task: Question Answering
Input (English): Background Paragraph: Arbuscular mycorrhizal fungi vary across many environmental gradients. Their tolerance to freezing and drying is known to shift between AM fungal taxa. AM fungi become less prevalent and diverse at higher soil nutrient and moisture concentrations, presumably because both plants allocate less carbon to AM fungi and AM fungi reallocate their resources to intraradical hyphae in these environmental conditions. Over the long term, these environmental conditions can even create local adaptation between plant hosts, AM fungi and the local soil nutrient concentrations. 
Story: Hill town had two large forests nearby. Lake forest had trees that were in a symbiotic relationship with a large variety of arbuscular mycorrhizal fungi. These fungi were less prevalent  in Brook forest. 
Question: Which forest had a greater diversity of arbuscular mycorrhizal fungi?
Output (English): Lake.
