🔍 Explanation Summary:

- Each idiom has a figurative meaning, not literal.
- We matched the context of each sentence to the most appropriate idiom.
- Some idioms were used more than once (like *let the cat out of the bag*), which is okay as long as it fits the meaning.
- Pay attention to grammar (e.g., “I have lost my marbles” vs. “I have lost my marbles” — past tense is needed here).
