• Identifying the Comparison: The sentence uses the word "than", which is a clear indicator that a comparative degree is required. We are comparing Mita to a group ("many other kids").
2. Grammatical Rule: For short adjectives (usually one syllable like smart), the comparative degree is formed by adding the suffix "-er".
Positive: Smart
Comparative: Smarter
Superlative: Smartest
3. Sentence Structure: The correct structure is: [Noun] + [Verb] + [Comparative Adjective] + than + [Noun/Pronoun]. Therefore, "Mita is smarter than many other kids..." is the only grammatically correct version.
