"Rigardu, estas ankoraŭ unu peco da ĉokolado en la skatolo."
Translation:Look, there is still one piece of chocolate in the box.
Why I can't say a piece instead of 1 or one piece?
In case anybody is wondering, I would expect the course - for sentences like this one only - to accept da or de.
Why would you point that out?!
(See what I did there?
Because, y'know, brownies are chocolate.
Nice. I s'pose that makes sense.
