Why do I need to use meg here and not és ? - "Magas vagy és alacsony vagyok"

I do not understand why I have the wrong answer Magas vagy meg alacsony vagyok Could you tell me? :)

I thought the te and the "en" were implied in vagy and vagyok. (I wrote "Magas vagy, es alacsony vagyok...sorry, I cannot access the accents in this format.)

Why not "pedig" here?

Can i put vagyok here as in "Te magas vagy, én meg alacsony vagyok"?

Why is Te vagy magas not acceptable? does vagy always go at the end?

Is "vagy" required here, or could it be left out?

Do the prononus strictly need to be there? What about magas vagy, de alacsony vagyok?

Should "Magas vagy és alacsony vagyok" be accepted?

I've used "Te" instead of "Ön" and my answer is not correct. Why is that? (My whole answer was "Te magas, én pedig alacsony")

I put meg before én. Is this acceptable? Te magas vagy, meg én alacsony.

Beside the german learnig ... the maghiar structure of learning is not that good , in german the would learn me some words like tall , short and so on and after would give me this kind os sentences ... but here ..... take the sentance .... translate ... . And beside the structure of the sentances are different than english ... so even worse

Why can't I write, 'Te magas vagy es alacsony vagyok'??

Ez szó szerint így lenne: "Te magas vagy, és én alacsony vagyok"- mégsem fogadta el : (
