Answer:
The correct answer is:
1. comparative: bigger
2. positive: big
3. superlative: biggest
Explanation:
A comparative adjective compares differences between two objects. For regural adjectives, we just add "er" to it. If the adjectiveis a single sillable word and ends with consonant, we double the last consonant as in "bigger". Example: "my car is bigger than my sister´s"
We use a superlative adjective when describing an object that is higher or lower in a quality. Example: biggest. We form a superlative adjective in this case by adding "est" and doubling the final consonant of the word. Example: "My car is the biggest one in the family"
A positive adjective is just describing a quality or characteristic of a noun. Example: "My car is big"
