My question is based on Past Simple and Past Progressive. I had a test a couple weeks ago, and there was this sentence with 2 verbs that you had to choose one to make the sentence true grammatically:
She collected / was collecting stickers last year.
It turns out that the right answer is "collected".
Doesn't it depend on the verb? Because you can collect stuff for a continuous period of time. If you judge by the rest of the sentence, it's absolutely "collected" (Past Simple), because there is nothing mentioned about how she collected stickers for a continuous period of time.
