I've been working on RT's online Russian lessons.
- Дмитрий Владимирович ещё не … кольцо.
There is a multi choice question among the options were покупал and купил, купил was correct. This struck me as strange. If he was yet to buy the ring wouldn't it be perfective (покупал) I would have thought купил would imply an ongoing process i.e. he was buying rings?
Guidance on this will be much appreciated. Cheers.
