Answer the following question given this paragraph: 

Materials that have high resistance to electric current are called electric insulators . Examples include most nonmetallic solids, such as wood, rubber, and plastic. Their atoms hold onto their electrons tightly, so electric current cannot flow freely through them. Dry air is also an electric insulator. You can learn more about electric insulators—as well as how to test whether a material is an insulator—by doing the activity at this URL:.
