This is a hard one! espcially the last part!
What would "Are these letters?" be in Latin?
I wrote: "what does you write, Marcus? Are they letters? and was marked as wrong. "Scribis" may be translated as present or present progressive tense. Why was marked my answer as wrong?
Because it would be 'What do you write, Marcus?'. 'Does' is not the second person form.
Why not "are there letters?"
