Learn Spanish (Latin America): La pirámide no fue restaurada porque el proyecto fue cancelado. - The pyramid was not restored because the project was canceled.

In the passive voice, the past participle acts like an adjective describing the subject. Since la pirámide is feminine, it takes the feminine ending restaurada. El proyecto is masculine, so it takes the masculine ending cancelado.

Why use the preterite fue instead of the imperfect era?

We use the preterite fue because these are viewed as completed past events. The cancellation was a specific event that occurred and ended. If we used era, it would sound like a continuous, ongoing process or a background description rather than a single event.

Could I use estuvo instead of fue here?

Not if you want to talk about the action itself. Using ser (like fue) in the passive voice focuses on the event taking place. If you used estar (like estuvo), it would describe the resulting state of the pyramid or project, rather than the action of restoring or canceling it.
