Select the correct tense: The documents had been destroyed in the floods.

Answer: Past perfect (passive voice).

Explanation: The verb phrase 'had been destroyed' is formed with 'had' + 'been' + the past participle 'destroyed', which is the past perfect passive form.

• Structure: had + been + past participle → past perfect passive.

• Meaning: it indicates the destruction happened before another past event or time.

• Why 'Simple past' is not correct: simple past passive would be 'were destroyed' and does not use 'had'.

• Why 'Past continuous' is not correct: past continuous passive would be 'were being destroyed', which expresses an ongoing past action, not a completed action before another past time.

• Why 'Past perfect continuous' is not correct: the active past perfect continuous is 'had been destroying'; the passive continuous ('had been being destroyed') is rare and does not match 'had been destroyed'.

Example: By the time the rescue team arrived, the documents had been destroyed.
