To effectively compare two countries based on the data in the graph (which I can't see), I can guide you on how to frame your response. For instance, if you choose Country A and Country B, you might say:
"Country A experienced significantly higher casualties due to ongoing civil conflict exacerbated by a weak central government and ethnic tensions, leading to widespread violence in urban areas. In contrast, Country B, while also facing turmoil, benefitted from international support and a more stable governance structure, which helped mitigate the impact of recent events. The differences in government response and external intervention played crucial roles in the contrasting casualty figures between the two nations."
Make sure to incorporate specific events and location details relevant to your course to strengthen your answer.
