{"knowledge_schema": {"broad_category": "Astronomy \u2192 Exoplanets \u2192 Planetary Density", "refinement": "This problem involves comparing the densities of different exoplanets based on their mass and composition.", "specific_scope": "The focus is on determining which of the given exoplanets has the highest density, considering their mass and the assumption of similar composition to Earth.", "goal": "Identify the exoplanet with the highest density among the provided options."}, "summary": "This problem requires understanding the concept of density in relation to mass and volume. The candidates include exoplanets with varying masses and compositions, and the goal is to determine which one has the highest density. By analyzing the mass and the assumption of similar composition to Earth, we can conclude that the planet with 5 times the mass of Earth (option c) will have the highest density due to the way density scales with mass and volume."}
