According to what I had learnt many years ago in Latin and reading the comments, my correct answer was marked as incorrect. I am grateful for the comments, just to make sure that I am relearning correct Latin. It would be good if Duo would revise the Latin course better sooner than later.
Ok. I am putting it here, but it can go anywhere. In Latin "c" is spelled like in e.g. "car" before "a", "o" and "u" and all consonants. Before "i" and "e" however it is spelled "ts": so civitas is "tsiveetas" NOT "qiveetas". Please change that. It gets annoying after every time I hear it
