this is my code:
proc choseWords(answerType: string): string =
  let good = ("Very well!", "Bravo!", "Thats it!", "Awsome!", "Amazing!")
  let bad = ("Sorry.", "Next time will be better.", "Think a bit harder.", "Bad
luck...", "Don't give up!")
  var words = ""
  let i = rand(0..2)
  if answerType == "good":
    words = good[i]
  else:
    words = bad[i]
  return words
