Task: Question Answering
Input (English): Background Paragraph: Predators play an important role in an ecosystem. For example, if they did not exist, then a single species could become dominant over others. Grazers on a grassland keep grass from growing out of control. Predators can be keystone species . These are species that can have a large effect on the balance of organisms in an ecosystem. For example, if all of the wolves are removed from a population, then the population of deer or rabbits may increase. If there are too many deer, then they may decrease the amount of plants or grasses in the ecosystem. Decreased levels of producers may then have a detrimental effect on the whole ecosystem. In this example, the wolves would be a keystone species. 
Story: Large birds are natural predators of rodents. Unfortunately, rodents consume crops in farmlands. In recent years, use of chemicals in agriculture has seen reduced number of large birds in Germany. But in some places in France farmers are cautions about using chemicals in agriculture. As a result, large bird population had been stable in France. 
Question: In which country ecosystem would be less balanced, France or Germany?
Output (English): Germany.
