Which word can mean to produce an annoying sound through friction?

• A. Gravity
• B. Grate
• C. Global
• D. Goad

Answer: (B)

This item centers on a verb that describes making an annoying sound by rubbing surfaces. Grate fits perfectly because when something grates, it rubs or scrapes against another surface in a way that produces a harsh, unpleasant noise. It also carries the sense of irritation—something that grates on you can annoy you—but the key idea here is the friction-generated sound.

Gravity refers to the force of attraction between objects, not a sound. Global means worldwide. Goad means to provoke or urge someone to action, which can irritate but doesn’t describe a sound produced by friction.
