Explanation:

When working unsafely with machines, cuts are a very common injury. Machines often have sharp parts or moving blades that can easily slice through skin if proper safety precautions (like guards) are not in place. Bruising is more of a soft - tissue injury from impact but not as common as cuts from machine - related incidents. Broken bones would require more forceful and specific types of trauma (like a heavy machine part falling on a limb) which is less frequent compared to the constant risk of cuts. Amputation is a severe and less common injury (though extremely dangerous) as it requires a more catastrophic machine failure or misuse scenario.
