For example, I was asked to fill in passive verbs in the following:
Great damage _____ (do) when the country _____ (rock) by an earthquake.
"The country" suggests occurrence in a past tense. Can I use the present perfect or past perfect after "when"?
- Great damage was done when the country has been rocked by an earthquake - I'm not sure because it isn't necessary relates to the present but does omits a specific time of occurrence
- Great damage was done when the country had been rocked by an earthquake - it is suggested that the two actions happen approximately very close to each other which is not past perfect.
