Respuesta :

Answer:

The answer is d: supported, suspended, and aerial lift trucks

Explanation:

An elevated temporary work platform is called a scaffold. Scaffolds can be divided into two categories:

Supported scaffolds are made up of one or more platforms that are held up by rigid parts like, for example, poles, frames and legs.

The scaffolds that hang from ropes or another pliable, above support, consisting of one or more platforms are suspended scaffolds

Aerial lifts, in particular, can be thought of as different kinds of supported scaffolds.
