I too see no reason against asking {ben 'ar}. Indeed, {ben 'ar bIboghpu'} is the usual way to ask someone’s age.

Can I say {ben 'ar Sorvo' vIghro' Dajotlhpu'}, for "how many years ago did you take down the cat from the tree" ?

Or is it that because of some reason, we can't use the {'ar} with {ben} ?
