Let's fill in the blanks with the appropriate comparative or superlative forms of the adjectives and adverbs in parentheses:

1. The weather is finer today than it was yesterday.
2. London is one of the biggest cities in the world.
3. This sentence is more difficult than the first one.
4. This dictation is not so easy as the last one.
5. Which is the highest mountain in the world?
6. His face was getting redder and redder.
7. This present is the best of all.
8. Your composition was the worst in the class.
9. The cat will be much happier in her new home.
10. I am not so tall as Jimmy.
11. Athens is farther (or further) from London than Rome is.
12. This film is as interesting as the one we saw last week.
13. They have more hens than we have, but they get fewer eggs.

These answers are based on the rules for forming comparatives and superlatives in English. For one-syllable adjectives, generally, we add "-er" for the comparative (e.g., "fine" becomes "finer") and "-est" for the superlative (e.g., "big" becomes "biggest"). For most two-syllable adjectives and all adjectives with more than two syllables, we use "more" for the comparative and "most" for the superlative (e.g., "difficult" becomes "more difficult"). However, there are irregular adjectives, like "good" and "bad," which become "better" and "worse" respectively in their comparative forms, and "best" and "worst" in their superlative forms. The word "happy" ends in a consonant plus "y," so we change "y" to "i" and add "er" for the comparative ("happier") and "est" for the superlative ("happiest").
