Arrange the urban/place hierarchy by containment from smallest unit to larger aggregations. 1. Apartment 2. Town 3. Street 4. Building 5. Complex

Introduction / Context:
Place hierarchies can be ordered by physical containment and administrative scale.

Given Data / Assumptions:

• Apartment is a unit inside a building.
• Building may belong to a complex (group of buildings).
• Complex sits on/along a street.
• Streets belong to a town.

Concept / Approach:
Order by smallest contained unit to larger container: unit → building → complex → street → town.

Step-by-Step Solution:
1 Apartment.4 Building containing apartments.5 Complex containing buildings.3 Street serving the complex.2 Town including the street network.

Verification / Alternative check:
Check if each element can logically contain the previous one.

Why Other Options Are Wrong:
Sequences that place town before street or complex before building break containment logic.

Common Pitfalls:
Confusing administrative boundaries with private developments; however, the general containment order remains sound.

Final Answer:
1, 4, 5, 3, 2
