### Chinese: 你确保是新鲜煮的食物，而不是旧的？
### English: Are you sure these are foods cooked just now, but not cooked before?
### Errors: There is a minor error at "these are foods cook". There is a minor error at "just now". There is a minor error at "not cooked before".

### Improved English: Are you sure the food was freshly cooked and not from before?
