Which word describes a very hard material made of carbon and one or more heavy metals, used in a saw blade?

• A. Carbide
• B. Awash
• C. Dismal
• D. Straggly

Answer: (A)

A very hard material made of carbon and a heavy metal, used in a saw blade, is called carbide. In industrial tools, tungsten carbide is a prime example—carbon bonded with tungsten creates a compound that is exceptionally hard and wear-resistant, which keeps saw blades sharp and effective through tough cutting jobs. The other options don’t describe a material at all; awash means flooded or covered, dismal means gloomy, and straggly means spread out or irregular in growth. These words refer to states or appearances, not a hard cutting material.
