Questions & Answers about Она вдруг вспомнила про билеты.
Why does this sentence use про билеты instead of о билетах?
Both mean 'about the tickets', but using про with the accusative case is more conversational and typical for everyday spoken Russian. The preposition о with the prepositional case (о билетах) is slightly more formal or neutral.
Could we use the imperfective verb вспоминала here instead?
No, because the adverb вдруг (suddenly) signals a spontaneous, one-time realization. The perfective aspect (вспомнила) is required to show that the action of remembering was an instant, completed event.
Is there a difference between вдруг and внезапно for 'suddenly' in this context?
They are often interchangeable, but вдруг is perfect for a sudden internal thought or realization like remembering something. Внезапно sounds a bit more dramatic and is usually used for abrupt external events, like a sudden storm or a loud noise.
How would this sentence look if we applied the 'не успел ... как' structure from the current lesson?
You would pair не успела with the perfective infinitive вспомнить. For example: Не успела она вспомнить про билеты, как поезд уехал (No sooner had she remembered the tickets than the train left).
