She is the dullest girl in the class.
Select the correct positive degree of the above.

The correct answer is Option D (No other girl in the class is as dull as she.).

Key Points:
• This question tests the transformation of sentences across different Degrees of Comparison (Superlative to Positive) without changing the meaning.
• Option 4 is correct. The original sentence is in the superlative degree ('the dullest'), indicating that she surpasses all others in dullness in that specific group. To convert this to the positive degree, we use the structure 'No other + noun + verb + as [adjective] as + subject'. Thus, 'No other girl in the class is as dull as she' conveys the exact same meaning.
• Option 1 ('Very few...') is used when the superlative is 'one of the dullest', which is not the case here. Option 2 is comparative, not positive. Option 3 ('as dull as any other') is grammatically awkward and typically used for comparative forms ('duller than any other').
• When converting a direct superlative ('the + -est') to positive, always start with 'No other'.
• Key Takeaway: Remember: 'The + superlative' transforms into 'No other + ... + as [adj] as' in the positive degree.
