The pressing comb with an on/off switch or thermostat is called a/an _____ pressing comb.

• A. Regular
• B. Electric
• C. Thermal
• D. Auto

Answer: (B)

When a pressing comb has its own on/off switch or a built-in thermostat, it is powered by electricity and designed to regulate heat. That combination—electric heating plus adjustable temperature control—defines an electric pressing comb. This setup lets you turn the heat on and off and keep it at a consistent, safe level to straighten hair without scorching it.

A regular pressing comb gets heat from an external source, like a stove, and lacks built-in temperature control. A thermal pressing comb suggests a design that preserves heat but isn’t inherently defined by having an electrical control. So the presence of an electric switch or thermostat is the clue that it’s an electric pressing comb.
