【参考答案及解析】
Rationale: Data can be lost or corrupted as the result of deliberate actions such as fraud, sabotage, commercial espionage or malicious damage - as well as human error. The other statements are true: new staff pose a security risk because of the risk of human error (if they are inexperienced or untrained)； it is impossible to prevent all threats (important to be realistic!)； and smoke detectors are an example of protection from physical risks (in this case, fire).Pitfalls: Don't forget physical security measures: you may have discounted Option D too quickly. Data security also involvesprotection against fire, flood, interruption of power source and so on.
