Humber/Ontario Real Estate Course 4 Exam Practice

Which of the following statements is correct regarding brick walls?

1. Brick walls are entirely out of fashion and not used in load-bearing structures.

2. Brick walls can be recognized by the absence of headers.

3. Brick walls can show a wavy look if constructed too fast without adequate mortar curing time.

4. Roof rafters spreading will never harm the structural reliability of a brick wall.

The correct answer is: Brick walls can show a wavy look if constructed too fast without adequate mortar curing time.

The correct statement regarding brick walls is that they can show a wavy look if constructed too fast without adequate mortar curing time. When brick walls are constructed rapidly, and the mortar does not have sufficient time to cure properly, the bricks may not bond effectively. This can lead to structural issues, including a wavy appearance in the wall. The integrity of the wall depends significantly on the quality of the mortar joint and its curing process, which is essential for providing stability and a uniform appearance. Other options refer to incorrect or misleading statements about brick walls. For example, while brick walls may not be as commonly used in some newer designs compared to other materials, they are still a vital component in many load-bearing structures. Additionally, the presence or absence of headers does not solely define brick walls, as various bricklaying techniques can be utilized. Lastly, roof rafters spreading can indeed affect the structural reliability of a brick wall; if roof loads are not adequately supported, this can create tension and stress on the walls, especially if they are not designed to handle such forces. Therefore, the correct answer highlights an important aspect of brick wall construction that is critical for ensuring quality and durability.
