"They have forty glasses, we have fifty."
Translation:Ei au patruzeci de pahare, noi avem cincizeci.
Yes I dropped the "noi" pronoun and just used "avem" verb conjugation and it was marked wrong. Is this not acceptable or is it just an error on Duolingo's side?
EDIT: I tried a couple of different variations of this. The first time I tried with neither pronoun ("EI" and "noi") and it was marked incorrect. The second time I omitted the first pronoun, "Ei" but included the "noi" pronoun and it was marked correct. This exercise seems to require the second pronoun.
