b. keep the blade sharp
c. protect the surface under the object
d. avoid electrocution

Answer:

c. protect the surface under the object

When using a utility knife, placing a piece of scrap under the object you are cutting helps protect the surface under the object. Placing a piece of scrap under the object you are cutting with a utility knife serves the purpose of protecting the surface underneath.

Utility knives are commonly used for various cutting tasks, such as trimming materials, opening packages, or performing DIY projects. By placing a scrap piece of material, such as cardboard or wood, underneath the object being cut, you create a protective barrier between the sharp blade and the surface below.

The scrap piece acts as a cushion or sacrificial layer that absorbs the impact of the knife, preventing it from directly contacting and potentially damaging the underlying environment. This is particularly important when cutting materials that can easily scratch, scrape, or leave marks, such as tabletops, countertops, or flooring. By using a scrap piece, you can minimize the risk of accidentally scratching or damaging the surface.
