Explain why ABC may need employees with different skills in its e-waste business than in its concrete business.

• A. E-waste requires only simple, unskilled labor.
• B. Recovering metals from circuit boards requires scientific, chemical, and technical expertise that differs from traditional concrete manufacturing skills.
• C. Concrete manufacturing skills are sufficient for e-waste recovery.
• D. The HR department can train all staff identically.

Answer: (B)

The main idea here is that different lines of business require different technical skills and knowledge. In e-waste, the work involves disassembling electronic devices, safely handling hazardous materials, and recovering metals from circuit boards. These tasks rely on scientific, chemical, and technical expertise, along with strict safety and environmental regulations, to process materials correctly and efficiently.

That contrasts with concrete manufacturing, where the focus is on mix design, batching, plant operation, quality control, and maintenance of concrete production processes. Those skills don’t automatically cover the specialized methods and safety protocols used in e-waste recycling.

So, the company would need employees with scientific, chemical, and technical training for the e-waste side, while the concrete side relies on different production-oriented skills. The other options imply e-waste is simple, that concrete skills cover recovery, or that HR can train everyone identically, which isn’t realistic given the distinct technical requirements and regulatory considerations.
