Emery cloth is used for polishing metal and is lubricated with water and oil. Which option describes this tool?

• A. Emery cloth
• B. Wet and dry paper
• C. Metal polish
• D. Bench sheers

Answer: (A)

The main idea here is recognizing an abrasive tool used to finish metal surfaces, where a cloth backing allows the abrasive to conform to shapes and be used with lubrication to control heat and prevent loading. This description fits emery cloth: a cloth-backed abrasive sheet that contains emery grains and is commonly used for polishing metal, often with water or oil to reduce friction and carry away debris.

That’s why it’s the best choice—the term itself matches the item, and the use with water and oil aligns with how emery cloth is typically used to get a smooth metal surface. Wet and dry paper is a sandpaper option with paper backing and is not described as emery cloth. Metal polish is a paste, not an abrasive sheet, and bench sheers are cutting tools, not methods for polishing.
