"I do not know what are you going to ask" was rejected.
Same for me, and I was in a really good streak
In English, if the sentence is a question, the verb should come after "what" or any other question word. This sentence is not a question; the "what" introduces the a relative clause, so the verb should come after the subject "you."
How would you translate "I do not know that you are going to ask" (that instead of what)?
"Eu não sei que você vai perguntar". If you hint word for word you'll find o=the, que=that. But, if you find "o que", the translation is what
In French it would be "ce que" right?
Yup!! = "je ne sais pas ce que tu vas demander?" (Right?)
