Q55: Consider the following statements regarding sentence transformations:

1. The active sentence "Should we protect the environment at the cost of industrial growth?" converts to the passive voice as "Should the environment be protected at the cost of industrial growth?"
2. The active sentence "Will my uncle pay my tuition fee?" converts to the passive voice as "Will my tuition fee be paid by my uncle?"
3. The active sentence "Must we protect the endangered species?" converts to the passive voice as "Must the endangered species protected by us?"

Which of the above statements is/are correct?
A
Only 1 and 2
B
Only 1 and 3
C
Only 2 and 3
D
All 1, 2, and 3
✅ Correct Answer: A
🎯 Quick Answer:
Statements 1 and 2 correctly execute interrogative modal shifts. Statement 3 omits a mandatory structural word.
Concept Definition: These examples test sentences that begin with modal auxiliary verbs (Should, Will, Must) functioning as questions.
Structural Breakdown: The formula for an interrogative modal passive is strictly: "Modal + Object + be + V3 + by + Subject". Statements 1 and 2 follow this template exactly, retaining the modal at the front of the sentence.
Historical/Related Context: Interrogative modals test a candidate's structural discipline.
These specific variations are drawn from the March 2026 objective test banks for banking exams, evaluating precision under timed pressure.
Causal Reasoning: Statement 3 is incorrect because it fails to include the base verb "be". The passive voice for modal verbs strictly requires this addition.
The correct passive sentence must read: "Must the endangered species be protected by us?"
