   • C. Clay soil amended with perlite
   • D. Recycled compost blended with native subsoil

Answer: B. Loam or sandy loam with 2–5% organic matter and pH 5.5–7.0

Class B topsoil is commonly defined as loam or sandy loam with 2–5% organic matter and a pH range of 5.5–7.0, suitable for most planting applications.

Answer: B. Open, unoccupied areas that define or enhance featured elements

Negative space is the intentional void or open area around and between design elements that gives them visual definition and breathing room.

Answer: B. By ensuring the project adheres to local regulations and standards

Regulatory compliance is non-negotiable in construction to ensure safety, environmental protection, and legal adherence. Landscape architects must thoroughly understand and ensure their projects meet all local building codes, zoning ordinances, environmental laws, and accessibility standards. This prevents legal issues, avoids costly delays, and ensures public welfare.
