The event itself is the topic in each case, with no agent to name. Select all sentences that use their intransitive verbs correctly.
The eclipse was occurred just after sunset.
The delay happened outside the signal area.✓Richtige Antwort
Two saplings were died during the dry spell.
The relief convoy arrived before the bridge closed.✓Richtige Antwort
Erklärung
The delay happened and the convoy arrived are active clauses because neither verb supplies an object for a passive transformation. The alternatives wrongly attach passive auxiliaries to intransitive verbs.
