1 Answer

B. Her mother told her to zip her lip.

Explanation:

An idiom is saying something but not meaning it literally.

A. Her face was like the moon at midnight, that is a simile because it's comparing her face and the moon at midnight.

B. Her mother told her to zip her lip, that's an idiom because you can't actually zip your lip, her mother is just telling her to be quiet.

C. Her mitt flew up to catch the ball as it zoomed over her head, that's a hyperbole which exaggerates the truth.

D. Her mood changed as quickly as the second hand on watch is a simile because it's comparing her mood and the second hand.

An idiom is just an experssion. It has its own meaning than the words actually being used and you learn idioms but just hearing them and asking what they mean.
