shouldnt this be also 'tu închizi cuptorul'?
this happens a lot, it is not clear from the english sentence if duolingo wants singular or plural...
It can be that too, and it's accepted as well.
Where is the 'you' inferred from? The conjugation of the noun?
Yes, the verb hints that it can only be you (plural form).
Since you're much more likely in everyday life to speak to one person than to a group, I can't help but wish that Duolingo would emphasize tu, not voi. But the opposite seems to be true.
Why "YOU" only VOI? YOU is TU ! Why wrong "tu ai închis cuptorul"?
For example that it's a past sentence? :D
"Tu închizi cuptorul" este corect?
