Compare the Hoyt sector model and the multiple-nuclei model in urban geography.

• A. Hoyt sector model divides a city into wedge-shaped sectors along transport routes; multiple-nuclei model posits several centers of activity as distinct nuclei.
• B. Hoyt sector model uses concentric rings; multiple-nuclei uses sectors along roads.
• C. Hoyt is for rural settlements; multiple-nuclei is for megacities only.
• D. Hoyt is a 19th-century model; multiple-nuclei is a 18th-century model.

Answer: (A)

When we look at how cities organize activities, two classic ideas explain different patterns of growth. The statement contrasts the Hoyt sector model with the multiple-nuclei model, and the best description is that the city develops wedge-shaped sectors radiating out from the central business district along transport routes, while there are several centers of activity that function as distinct nuclei.

The Hoyt sector model envisions growth along transportation lines, so the city splits into wedge-shaped sectors that extend from the center. These sectors reflect how railways, streets, and other corridors guide where people live and work, creating pie-slice patterns that radiate outward from the core.

In contrast, the multiple-nuclei model argues that a city does not rely on a single CBD. Instead, it contains several centers of activity—shopping districts, ports, universities, airports, and other nodal points—around which surrounding land uses cluster. These centers compete or complement each other, with corridors and residential areas forming around each nucleus.

That combination—wedge-shaped sectors along transport routes plus multiple centers of activity as distinct nuclei—is what the statement describes as the difference between the two models. The other options mix up the patterns (concentric rings belong to a different model; the notion of sectors along roads isn’t accurate for the multiple-nuclei idea) or misstate the scope and history of the models.
