Which material is described as deciduous trees with broad leaves that grow slowly (about 80–100 years), making sustainable growth more challenging?

• A. Hardwood
• B. Manufactured board
• C. Blockboard
• D. Chipboard

Answer: (A)

Hardwoods come from deciduous trees with broad leaves, and they generally grow more slowly than softwoods. Because these trees can take around 80–100 years to reach harvest size, renewing supplies sustainably requires long-term forest management and careful planning. That slow growth makes sustainable harvesting more challenging, which is why this material fits the description. Engineered boards like manufactured board, blockboard, and chipboard aren’t tied to a single slow-growing tree’s life cycle; they’re made from wood fibers or veneers and can use fast-growing species or recycled material, so the specific slow-growing, broad-leaved-tree characteristic doesn’t apply to them.
