Why "Why are sons of Zofie not here" is not accepted?
God, I've failed this question a dozen of times already....
Edited. Thanks :)
Your sentence requires a definite article.
Starduo is right. The word "the" is required for proper English grammar in this sentence.
where does "synove" come from?
I guess it is nominative plural of syn
'Why are not here Žofie's sons' is not accepted; why?
because is messed up the word order.
"Why Žofie's sons are not here" isn't accepted?
That word order is incorrect in English. If you used it, you would probably be understood, but it should not be an accepted translation.
