You are tasked with breaking down a long article about the history of renewable energy into semantically coherent segments for a reward model. Each segment should focus on a distinct sub-topic (e.g., early water wheels, the development of solar panels, modern wind turbine technology). Write a clear and effective prompt that you would provide to a Large Language Model to perform this segmentation. Your prompt should instruct the model to insert a specific marker (e.g., [SEGMENT]) at the end of each identified semantic segment.
