Q94: Consider the following statements regarding sentence transformations:

1. The active sentence "Who painted this magnificent portrait of the king?" converts to the passive voice as "By whom was this magnificent portrait of the king painted?"
2. The active sentence "Which novel are you currently reading for your literature class?" converts to the passive voice as "Which novel is being read by you currently for your literature class?"
3. The active sentence "How many electric cars did the company manufacture last quarter?" converts to the passive voice as "How many electric cars did manufactured by the company last quarter?"

Which of the above statements is/are correct?
A
Only 1 and 3
B
Only 1 and 2
C
Only 2 and 3
D
All 1, 2, and 3
✅ Correct Answer: B
🎯 Quick Answer:
Statements 1 and 2 expertly execute complex interrogative shifts. Statement 3 fails structurally by combining active and passive auxiliary verbs.
Concept Definition: These examples test multi-word interrogatives ("Who", "Which novel", "How many electric cars") that function as entire interrogative units and must not be broken apart during voice conversion.
Structural Breakdown: Statement 1 flawlessly shifts "Who" to "By whom". Statement 2 correctly treats "Which novel" as the passive subject, linking it to "is being read." Historical/Related Context: "How many" questions are notorious for causing syntax errors.
This exact format appeared in the May 2024 CHSL shifts, testing if candidates knew how to properly replace the dummy auxiliary "did". Causal Reasoning: Statement 3 is incorrect because it retains the active dummy auxiliary "did" while simultaneously attempting to use the past participle "manufactured." In simple past passive questions, "did" must be completely replaced by "was" or "were". The correct passive conversion is "How many electric cars were manufactured by the company last quarter?"
