9 Correct the mistakes. 1 This is the better program on TV! 2 Paris is most beautiful than London. 3 Russia is the colder than Spain. 4 I eat less of you. 5 My schoolbag is heaviest than yours. 6 Is your dress most expensive than mine?

Here are the corrected sentences: 1. This is a better program on TV! *Explanation*: The word 'better' already implies a comparison, so you need the article 'a' before it. 2. Paris is more beautiful than London. *Explanation*: For longer adjectives like 'beautiful,' we use 'more' to form the comparative degree. 3. Russia is colder than Spain. *Explanation*: The comparative form of 'cold' is 'colder'. 4. I eat less than you. *Explanation*: 'Less' requires 'than' to make a comparison. Also, you should eat less food than someone else, not less of someone else. 5. My schoolbag is heavier than yours. *Explanation*: The comparative form of 'heavy' is 'heavier.' The 'y' changes to 'i' before adding '-er'. 6. Is your dress more expensive than mine? *Explanation*: For longer adjectives like 'expensive,' we use 'more' to form the comparative degree.
