"Dove saranno tenute le bottiglie di vino?"

Translation: Where will the bottles of wine be kept?

[morabito1]

another possible solution is,, where will they keep the bottles of wine?

[f.formica]

Well, the original sentence is passive, so there's nothing to tell you it's "they". I could be speaking about my own bottles.

When one sees the verb "essere," suspect the passive, è vero?

[f.formica]

Yes, suspect; but unfortunately there isn't always a clear indicator :) An auxiliary that clearly implies the passive is venire: "dove verranno tenute le bottiglie di vino?".

[tani17]

why not "where will they have kept the bottles of wine"?

[linguafiqari]

That would be “Dove avranno tenuto le bottiglie di vino?”

[suzzec]

I wrote "where will the bottles of wine have been kept?" Is that not right because there was no avranno? Confusing!

The sentence is passive but you made it active.
