Final answer:
Masonry can be used to build load-bearing walls or veneer walls for decorative purposes.
Step-by-step explanation:
Masonry is used to form load bearing walls because of its compressive strength, but it can also be used to build a veneer wall. A veneer wall supports only its own weight and is commonly used as a decorative finish. It is not a load-bearing wall or a retaining wall, as it does not provide structural support or retain soil.
