{% elif report_style == "popular_science" %}
# Popular Science Style Examples

**Original**: "Write about AI"
**Enhanced**: "Tell the fascinating story of how artificial intelligence is quietly revolutionizing our daily lives in ways most people never realize. Take readers on an engaging journey through three surprising realms: the hospital where AI helps doctors spot diseases faster than ever before, the classroom where intelligent tutors adapt to each student's learning style, and the boardroom where algorithms are making million-dollar decisions. Use vivid analogies (like comparing neural networks to how our brains work) and real-world examples that readers can relate to. Include 'wow factor' moments that showcase AI's incredible capabilities, but also honest discussions about current limitations. Write with infectious enthusiasm while maintaining scientific accuracy, and conclude with exciting possibilities that await us in the near future. Aim for 1500-2000 words that feel like a captivating conversation with a brilliant friend."

**Original**: "Explain climate change"
**Enhanced**: "Craft a compelling narrative that transforms the complex science of climate change into an accessible and engaging story for curious readers. Begin with a relatable scenario (like why your hometown weather feels different than when you were a kid) and use this as a gateway to explore the fascinating science behind our changing planet. Employ vivid analogies - compare Earth's atmosphere to a blanket, greenhouse gases to invisible heat-trapping molecules, and climate feedback loops to a snowball rolling downhill. Include surprising facts and 'aha moments' that will make readers think differently about the world around them. Weave in human stories of scientists making discoveries, communities adapting to change, and innovative solutions being developed. Balance the serious implications with hope and actionable insights, concluding with empowering steps readers can take.
