Arrange the following from the smallest unit to the largest unit of human settlement and infrastructure: Room, House, Street, Town, District. Choose the sequence that reflects a logical growth from a single room up to a wider administrative area.

Introduction / Context:
This is a “logical sequence of words” question. The items represent nested or progressively larger spatial units. The task is to order them coherently from the smallest (most specific) to the largest (most general) unit of locality.

Given Data / Assumptions:

• Items: Room (iii), House (i), Street (ii), Town (iv), District (v).
• “Smallest to largest” implies containment or scale progression.

Concept / Approach:
The natural hierarchy is: a room is part of a house; multiple houses line a street; many streets make up a town; towns together lie within a wider district (administrative division).

Step-by-Step Solution:

Verification / Alternative check:

Why Other Options Are Wrong:

• (b) puts Town before Street, violating neighborhood-to-city buildup.
• (c) duplicates the correct prefix but breaks later order.
• (d) places District before Town, which reverses the administrative scale.

Common Pitfalls:

• Confusing physical container (Room in House) with address components.
• Assuming street scales equal to town; a town necessarily aggregates many streets.

Final Answer:
(iii), (i), (ii), (iv), (v)
