2. Predicates are to be included for the following relations only (others must be learnt): father,mother,son,daughter,brother,sister,wife,husband/2 male,female,person/1 (child/3 & married/2 will be needed in defining these)
3. To assist you in the programming task some procedures are provided in the file $ai/prolog/family.pl which you MUST incorporate in your program (there are also additional hints and optional help predicates in this file).
4. Sentences of these types should be recognized by the system:
DO you know what AN R is ?
DOES P have AN R ?
PRINT EACH R of P.
PRINT EACH R. DO you know P ?
