Structural Drawing — Brick and tile (masonry) are widespread, mainstream construction systems worldwide; calling them “less common forms of building construction” is misleading.

Introduction / Context:
Masonry construction using brick and tile is a ubiquitous building method for residential, institutional, and even commercial structures. The statement that brick and tile are among the “less common” systems is inaccurate in both historical and contemporary contexts.

Given Data / Assumptions:

• Masonry includes fired clay brick, concrete masonry units, and tile systems.
• Use cases range from bearing walls to veneers and partitions.
• Availability and skill base are widespread globally.

Concept / Approach:
Commonness in construction is measured by installed base, material supply chains, and contractor familiarity. Brick and tile score high on all three, making them mainstream rather than rare. Even where steel or reinforced concrete frames dominate, brick or tile often provide infill or enclosure.

Step-by-Step Solution:
1) Identify typical building types (housing, schools, low-rise offices) that rely on masonry.2) Note material supply and workforce training supporting widespread adoption.3) Recognize hybrid systems (RC/steel frame + brick infill) as further evidence.4) Conclude that labeling brick and tile as “less common” is incorrect.

Verification / Alternative check:
Market surveys and building codes frequently treat masonry as a primary material with extensive design standards, which would not be the case for a “less common” system.

Why Other Options Are Wrong:
Limiting masonry to industrial plants, temporary sheds, or specific climates contradicts its broad usage.

Common Pitfalls:
Confusing “structural system” (frame vs bearing) with “enclosure material” and wrongly inferring rarity.

Final Answer:
Incorrect
