The sort of question I had in mind was of the form:

  ta ge vasru na go loi tcati gi loi ckafi gi vasru ma

or

  ta ge vasru pa da poi ke`a cmima loi tcati ce loi ckafi
  gi vasru ma

- as jimc has already suggested.

A neat way of saying it might be:

  ta vasru ma poi ke`a du pa da poi ke`a cmima loi tcati
  ce loi ckafi

or

  ta vasru ma poi ke`a na go tcati gi ckafi

[NB: by {go} I mean "iff". I may have misremembered this.]
