"This girl is a children's composer."
Translation:Эта девушка — детский композитор.
I am not an expert but i asked my wife who is russian and she said the only thing that would make her decide to use девушка would be the fact you that you are talking about a profession that a girl would not have but something that a young woman would. So if you key off that information, Девушка seems more appropriate.
why is детская композитора not accepted? Since this is a girl, but using the masculine form of the word?
I type using transliterated English instead of a Russian keyboard, and when I type "Eta devushka - detskii kompozitor", it says I am wrong and the correct answer is "Eta devushka — det-skii kompozitor."
Any idea why детский would be transliterated as det-skii instead of detskii?
Duolingo, you really need to add more error categories; for this, I get three possible errors I can report: audio is wrong, dictionary hints are wrong or the english is wrong. However, here, the problem is with the transliteration. det-skii works, detskii doesn't. That's a bizarre error, and you should fix it. These kinds of problems do not inspire an interest in paying for your product, especially as you also seem entirely disinterested in fixing errors and bugs.
