In a study of historical urban planning, researchers examined the growth of 'Garden Cities.' planners prioritized concentric rings of greenbelt land to limit urban sprawl.
| City | Greenbelt (%) | Pop. Density (per/km^2) |
| :--- | :--- | :--- |
| Letchworth | 42 | 850 |
| Welwyn | 38 | 920 |
| Stockley | 15 | 2,400 |
Which statement regarding the relationship between land use and density is most reasonably inferred?
- The Garden City model is the only effective method for preventing modern cities from exceeding a density of 1,000 people per km^2.
- There is a strong inverse correlation between the preservation of greenbelt land and the resulting population density of the city.
- Letchworth and Welwyn were more successful than Stockley because their densities remained below 1,000 people per km^2.
- Urban planners in Stockley were fundamentally opposed to the core tenets of the Garden City movement.
