    "Whose" mainly functions as genitive determiner, not subject or object, and hence it is not omissible: "I can't contact the people [whose house we're renting]". – BillJ Apr 21 at 15:27
  • You haven't shown us any sentences, so we don't know which ones you're talking about. – tchrist Apr 21 at 17:03
