______ covers the joints between walls and ceilings.

The correct answer is trim, which refers to the decorative finish that covers the joints between walls and ceilings. Trim is essentially the molding or finishing that helps create a smooth transition between the two surfaces, enhancing the overall aesthetic of a room. This finishing touch not only adds visual appeal but also serves functional purposes, such as hiding imperfections where the wall meets the ceiling.

In residential construction, trim can vary in style and material and is often painted or stained to match the interior decor of a home. It plays a significant role in the overall design and helps define spaces within a room.

Understanding the role of trim is crucial, as it helps in both construction and appraisal practices to assess the quality and completeness of a property’s interior finishes.
