Statement: The Government transferred the entire staff of police station X and ordered a magisterial inquiry into the mysterious death of a man in police custody. Assumptions: I. A magisterial inquiry can uncover the cause of death in custody. II. Transferring the entire staff helps ensure a free and fair inquiry.

Introduction / Context:
In suspected custodial-death cases, governments often combine fact-finding (independent inquiry) with administrative steps (transfers) to reduce interference. We must decide which assumptions are necessary for this twin action to be sensible.

Given Data / Assumptions:

• Magisterial inquiry is ordered.
• Entire station staff is transferred.
• I: Inquiry can reveal cause/circumstances.
• II: Transfers help fairness by preventing influence or evidence tampering.

Concept / Approach:
Fact-finding presupposes capability to discover truth; administrative insulation presupposes that those potentially involved should not remain in positions affecting the process. Both are standard integrity safeguards.

Step-by-Step Solution:
1) Without I, ordering an inquiry would be pointless.2) Without II, wholesale transfers would be unnecessary overreach; their logic is to remove conflict-of-interest risks.3) Therefore, both assumptions are necessary.

Verification / Alternative check:
Independent inquiries worldwide commonly rely on separation of potentially implicated personnel to preserve process integrity, reinforcing both I and II.

Why Other Options Are Wrong:
Any option omitting I or II ignores a core rationale for the dual measures.

Common Pitfalls:
Thinking that “inquiry” alone suffices; process design also guards against interference.

Final Answer:
Both I and II are implicit.
