Q6: Consider the following statements regarding sentence transformations:

1. The active sentence "You must obey the traffic rules" converts to the passive voice as "The traffic rules must be obeyed by you."
2. The active sentence "She can solve this complex puzzle" converts to the passive voice as "This complex puzzle could be solved by her."
3. The passive sentence "The environment ought to be protected by us" converts to the active voice as "We ought to protect the environment."

Which of the above statements is/are correct?
A
Only 1 and 3
B
Only 2 and 3
C
Only 1 and 2
D
All 1, 2, and 3
✅ Correct Answer: A
🎯 Quick Answer:
Statements 1 and 3 correctly process modal verbs. Statement 2 incorrectly alters the modal.
Concept Definition: These statements test the application of voice changes to sentences utilizing modal auxiliaries (must, can, ought to). Structural Breakdown: Statement 1 successfully applies "must be + V3". Statement 3 successfully strips "be" to return "ought to be protected" back to "ought to protect". Historical/Related Context: Similar to the "will/would" error, examiners use the "can/could" shift to trap students who confuse direct/indirect speech with active/passive voice, a very common sight in 2024 exam papers.
Causal Reasoning: Statement 2 is incorrect because the modal "can" has been shifted to its past tense form "could". In voice transformation, the modal must remain exactly the same.
The correct conversion is "This complex puzzle can be solved by her."
