I don't know what is stranger, that the mouse is eating meat or that they co-own it.
Because they are trying to teach Polish tenses using English tenses, and it fails and fails and fails, because language is not simplistic
I think because the thing it's describing is singular - nasza mysz is our (one) mouse.
How do we know this sentence is absolute present continue and can not be simple simple present? Because my answer was not accepted.
We don't know it, although Present Simple may be better rendered by "jada". Still, it should have worked, it's an accepted answer.
It could be nicer if they make us type in Polish more often instead of English but easy to moderate, I know polish have some complex words that are hard to remember how to type example: Mężczyzną
I can confirm, as previously mentioned above, that "our mouse eats meat" is not accepted.
Well, it's definitely on the list of accepted answers... I 'refreshed' them (made some change and reverted it), some say it can help... but what would be most helpful is if you could provide a screenshot next time an answer that you're sure of is rejected.
