Which object is cleared by the side or alley arms as part of their function?

• A. Buildings and trees
• B. Highways
• C. Telephone lines
• D. Transformer stations

Answer: (A)

Side or alley arms are attachments that reach out into the work area to push aside or remove obstacles that would block the operation. They’re meant to deal with large, solid objects that can intrude into the clearance path, such as buildings and trees. These are the kinds of things that hardware like this would physically clear to create a usable space. In contrast, highways are already open routes, and delicate utilities like telephone lines or transformer stations require special handling and aren’t simply “cleared” by these arms. So the object that fits the function described is buildings and trees.
