Jes. Tiu estis mia unua respondo sed duolingo ne ĝin akceptis.
I reported "Sofia went somewhither, but whither?", which is technically the most direct translation. We'll see if it gets accepted…
Yes, but as with hearing something said in any language you can usually work out the word from the sense of the sentence. In this case “sed” seemed to me to be the only word that could fit. I don’t always hear every word said to me in English, but it is very rare for me to misunderstand something because of that.
