Interchange of Sentences — Important Questions

The bag is so heavy that it cannot be carried.

The pattern is 'so + adjective + that + cannot/could not + be + past participle' for passive voice transformation. Option B misses the object in active voice. Option C uses 'very' instead of 'so'. Option D misses 'that' which is essential in the structure. The transformation maintains the meaning of impossibility due to excess.

No sooner did the bell ring than students rushed out.

With 'No sooner', we use inversion: 'No sooner + did/had + subject + base form + than'. For simple past, use 'did + base form'. Option B misses auxiliary verb. Option C incorrectly uses 'had + rang' instead of 'had + rung'. Option D uses 'did + rang' instead of 'did + ring'. Remember: did + base form, had + past participle.

Mumbai is the largest city in India.

Comparative 'larger than any other' converts to superlative 'the largest'. This shows Mumbai as the biggest among all cities. Option B is comparative form. Option C is also comparative in negative form. Option D uses positive degree 'large' without comparison. Superlative degree uses 'the + -est' or 'the most + adjective'.

Not everyone liked the performance.

When negating 'everyone', we use 'not everyone' which means 'some did not like'. Option A uses double negative (no one disliked = everyone liked). Option C changes meaning completely (nobody liked). Option D is too strong and changes the meaning. 'Not everyone' maintains partial negation rather than complete negation.
