Which component is described as a threaded sleeve with dual internal threads?

• A. barrel
• B. bolt
• C. secured
• D. round pan truss

Answer: (A)

The idea being tested is recognizing a hollow cylindrical part that accepts other pieces by threading on the inside. A threaded sleeve with dual internal threads means a hollow sleeve whose interior has threads at two locations (essentially two ends) to mate with two components. In this context, that description fits the barrel best. The barrel is a hollow cylindrical component designed to receive other parts by threading inside, often with ends that accept attachments from either side. The other options don’t describe a hollow sleeve with internal threading: a bolt has external threads, a secured isn’t a hardware part, and a round pan truss is a structural framework without threaded interiors.
