Which statement is true?

• A. Unishears can be used to cut in any direction.
• B. A torx screwdriver can tighten any type of screw.
• C. A portable band saw cannot cut through strut.
• D. When using a disk grinder you should never unplug it when changing disks.

Answer: (A)

The idea being tested is how tool design determines what you can do safely and effectively. Unishears are designed to cut sheet metal with control in multiple directions, including curves, which makes them suitable for trimming shapes when space is tight or angles are needed. That flexibility is why this statement is true: they can be used to cut in any direction as you guide the cut.

The other statements don’t fit because they describe capabilities or safety rules that aren’t accurate. A torx screwdriver is made for Torx screws and won’t properly tighten other screw types, so it isn’t universal. A portable band saw can indeed cut through strut with the right blade, so claiming it cannot is incorrect. For disk grinders, unplugging before changing discs is a fundamental safety practice; never unplugging contradicts safe procedure and can lead to injury.
