Which statement about drywall is correct?

1. Drywall can only be installed vertically, not horizontally.

2. Drywall was mostly replaced by plaster in residential construction.

3. Gypsum is commonly used to manufacture pre-made drywall.

4. Drywall is installed to provide structural integrity rather than decorative purposes like concealing pipes and wires.

5. Modern residential buildings do not use drywall.

6. Drywall installation requires specialized training.

The correct answer is: Gypsum is commonly used to manufacture pre-made drywall.

The correct answer is that gypsum is commonly used to manufacture pre-made drywall. This statement accurately reflects the core composition of drywall, which is primarily made from gypsum, a natural mineral. Gypsum provides the necessary properties that make drywall an effective material for construction, including its fire-resistant qualities, ease of installation, and soundproofing characteristics. The other statements are not accurate representations of drywall as a building material. While drywall can be installed in various orientations depending on specific structural and design needs, it is not restricted to vertical installation. Historically, plaster was commonly used; however, drywall has largely supplanted plaster in residential construction due to its ease of use and cost-effectiveness. Drywall is primarily intended to serve both functional and aesthetic roles in construction, including concealing wiring and plumbing, rather than solely providing structural integrity. It is also a standard material in modern building methods; therefore, it is incorrect to state that new residential buildings do not use drywall. Although specialized training can be beneficial for drywall installation, it is not a strict requirement, as many homeowners engage in DIY projects without formal training.
