For those who dont know: Latin doesn't have a definite article ("the"), and a sentence like this one could be understood as "you are a boy" or "you are the boy."
Latin does not have any articles at all. Neither a definite article ("the") nor an indefinite article ("a/an"). That is why "a boy" or "the boy" are equally good translations.
When selecting options, the "a" did not appear, so I couldn't put "You are a boy".
Did you report it with the Report Button? That's how we are processing the errors.
I did not have "a" as an option but "the" was - selecting it marked it correct.
It appears to be slightly off. It should be pronounced [ˈpʊ.ɛr] and she is pronouncing [pʊ.ˈɛr]
I think a non-english sounding speaker would be better. I find the male pronounciation much better than the female's that unfortunately sounds too unnatural and put on.
