Which of the above statements is/are correct?
✅ Correct Answer: A
🎯 Quick Answer:
Statements 1 and 2 correctly execute interrogative modal shifts. Statement 3 contains a critical tense violation.Structural Breakdown: Statement 1 correctly shifts "Who" to "By whom" while preserving the "can... be solved" structure.
Statement 2 seamlessly applies the "Modal + Object + be + V3" formula, dropping the vague subject "we" entirely.
Historical/Related Context: "Must" and "Can" questions test structural discipline.
Examiners frequently try to trick candidates by moving the modal verb away from the start of the sentence in the multiple-choice options.
Causal Reasoning: Statement 3 is incorrect because it converts a Simple Past active question ("Did they occupy") into a Present Perfect passive question ("Has... been occupied"). Voice rules strictly prohibit altering the tense.
The correct passive sentence is "Was the newly built coastal villa occupied by them?"
