Questions & Answers about Dopo che ebbero aperto la tomba, trovarono un frammento intatto.
Why do we use ebbero aperto here instead of the regular past perfect avevano aperto?
Ebbero aperto is the trapassato remoto (preterite perfect). It is used specifically to show that an action was completed immediately before another action in the distant, historical past. If you used the everyday trapassato prossimo (avevano aperto), it would sound mismatched with the historical past tense of trovarono.
What makes dopo che so important in this sentence?
The trapassato remoto is almost never used in a main clause. It relies heavily on time-related conjunctions like dopo che (after), non appena (as soon as), or quando (when) to connect it to the main action. It emphasizes that the opening of the tomb was fully completed before the finding of the fragment began.
Could we say hanno trovato instead of trovarono for the main action?
You could, but then you would have to change the first verb too! Trovarono is the passato remoto (distant past), which forces the preceding dependent action into the trapassato remoto. If you updated the sentence to the everyday past tense (hanno trovato), you would also change the first verb to the regular past perfect: Dopo che avevano aperto la tomba, hanno trovato...
Since la tomba is feminine, why isn't the participle feminine ()?
