"Kanin" (rabbit), "kort" (card, short), "kasse" (box) and "kat" (cat), all these words begin with a k and therefore they actually sound like k's. "Tak" (thanks) is pronounced like [tag], "bakke" (hill) like [bagge] and "taske" (bag) like [tasge]. You get the idea :) Generally k only sounds like k, when it's the first letter of a word. I can't think of any examples where this rule doesn't apply.
The right answer should be: An elephant does not speak Danish, because the duck is an "he" or a "she"... So in English it will be doesn't instead of "dont" "Don't" would be right if the subject was "You".
I hope my answer can help you!
Lots of succes! Kind regards, Hannah
