"Das ist nicht, warum Sie tranken, oder?"

why does this not fit "that wasn't why you drank, was it?"

[Acts16_31]

i wonder why can't you say "right?" in this sentence? "That is not why you drank, right?"

[siebolt]

"Das ist nicht .... oder?" is Präsens, "warum Sie tranken" is Imperfekt. You can't just change Präsens into Imperfekt even if there is a part of the phrase in Imperfekt.

[thomaswalsh75]

Yep, sorry, I was just focusing on Sie tranken and automatically took the whole sentance as Imperfekt.

I sounded a bit more severe than I meant, because your mistake is logical.
