Laminated wood offers several advantages over solid wood. Which of the following is NOT an advantage of laminated wood? 

To determine which option is NOT an advantage of laminated wood, let's evaluate each option:

1. Option 1: Since laminated wood is glued, wood of only large dimensions can be used, which increases the amount of waste.
   - This statement suggests that laminated wood requires large pieces of wood, leading to increased waste. In reality, laminated wood can be made from smaller pieces of wood glued together, which actually reduces waste by using smaller off-cuts and lower-quality wood efficiently. This statement is incorrect because it doesn't represent an advantage of laminated wood. In fact, it is a disadvantage, as it misrepresents how laminated wood is utilized.

2. Option 2: Structures can be designed with laminated wood based on the required strength, and low-grade wood can be positioned accordingly.
   - This is true and an advantage of laminated wood. Designers can place higher-grade wood where strength is needed and use lower-grade wood elsewhere, optimizing material use and cost.

3. Option 3: Individual boards, which are used in laminated wood due to their relative thinness, can be properly dried without checking (cracking), and defects, such as knots, can be removed.
   - This is also true and an advantage. Thinner boards used in lamination can be dried more effectively, reducing issues like checking and allowing for the removal of defects, leading to higher-quality end products.

4. Option 4: It can be used to fabricate large members that are impossible to be made from solid wood.
   - This is a well-known advantage of laminated wood. Large structural members can be fabricated by laminating smaller pieces, which is not possible with solid wood due to size limitations and imperfections.
