Which of the following is an example of a manufactured board?

Plywood is an example of a manufactured board because it is created by gluing together multiple layers of wood veneer, which are often sourced from different types of trees. This process not only utilizes otherwise wasteful wood byproducts but also enhances the strength and stability of the board compared to solid wood. The cross-layering of the veneers helps to prevent warping and splitting, making plywood a versatile material used in various applications like furniture, cabinetry, and construction.

In contrast, the other choices—oak, maple, and teak—are examples of solid hardwoods that are harvested directly from trees. These woods are prized for their natural grain patterns and durability but do not go through the manufacturing process that creates engineered products like plywood. Thus, understanding the distinction between solid wood and manufactured boards highlights why plywood is categorized differently.
