I've added that, it's possible here. The general idea is that it's reasonable to think that a Swedish determinate can mean an English possessive in cases where the first interpretation would be that you are talking about something that belongs to the subject – it's about something that you are expected to have. For instance, Vi borstar tänderna We probably brush our teeth, not just some other teeth. Vi köper äpplena We're not likely to buy apples that are already our own, so no way. Vi läser tidningarna There's no good reason to assume we're reading our own newspapers. It could happen in real life (although rarely) that tidningarna would be our newspapers but shouldn't happen in this course since it is unlikely.
