The test station is an automated manufacturing line needs to work without the tested part being ______ loaded onto it.

• A. Automatically
• B. Electronically
• C. Randomly
• D. Manually

Answer: (D)

The main idea is that automated systems are designed to run without human handling of parts. In an automated manufacturing line, you want parts to be fed into the process by conveyors, robots, or other automatic means, not by a person putting them in by hand. So the word that fits is the one that describes manual effort. Saying the line needs to work without the part being loaded by hand makes sense: it emphasizes that no human intervention is required for loading. The other terms would imply different loading methods (automatic or electronic feeding or random placement) that don’t capture the goal of eliminating manual handling in an automated system.
