Cmore faster
Dmore fast
Answer:
A. faster
Read Explanation:
Correct sentence: Monkeys are faster learners than elephants.
Explanation
Comparative degree: The sentence compares two groups of animals: monkeys and elephants. Therefore, we need the comparative form of the adjective fast.
Formation: For short adjectives such as fast, we generally add -er to form the comparative degree. Thus, fast → faster.
Use of “than”: The word than is commonly used after a comparative adjective to make a comparison.
Why not “more faster”? Using more with faster is incorrect because faster is already in the comparative degree.
Why not “very fast” or “more fast”? “Very fast” expresses a high degree without making a direct comparison, while “more fast” is not the standard comparative form.
Grammar rule: Positive degree → Comparative degree → Superlative degree
