Step 1: Understanding the Use of "Fewer" and "Less":
"Fewer" is used with countable nouns, while "less" is used with uncountable nouns. "Classes" is a countable noun, so we need to use "fewer." Step 2: Analyzing the Options:
- Less: Incorrect because "less" is used with uncountable nouns.
- Little: Incorrect because "little" is used with uncountable nouns and refers to a small quantity.
- Fewer: The correct choice because "fewer" is used with countable nouns like "classes."
- Any: This is incorrect because "any" is used for questions or negative sentences, not for expressing quantity in affirmative statements. Step 3: Conclusion:
The correct word is fewer, as it refers to a smaller number of countable items (classes).
