Try storing your third person verbs in a hash, keyed to their second person version. 
%verbs =
{ are  => 'is',
  do   => 'does',
  have => 'has',
}

If the verb doesn't change then leave it out. You should be able to do a simple replacement of the changed verbs (assuming that you don't change objects in the sentence). I doubt there are many verbs that change based on their object, especially since you're just working from a db of questions.
