Task: Question Generation
Input (English): Background Paragraph: Biodiversity is determined by many things, and one of them is abiotic stress. If an environment is highly stressful, biodiversity tends to be low. If abiotic stress does not have a strong presence in an area, the biodiversity will be much higher.This idea leads into the understanding of how abiotic stress and endangered species are related. It has been observed through a variety of environments that as the level of abiotic stress increases, the number of species decreases. This means that species are more likely to become population threatened, endangered, and even extinct, when and where abiotic stress is especially harsh. 
Story: Two neighboring regions were exposed to different levels of abiotic stress. Eastern region was exposed to high levels of abiotic stress, while Western region was almost stress-free.
Output (English): Which region had more animal species inhabiting it?
