Interpret the queries and guess(!) the answer(s) produced by the program:

1. day("Holiday").

2. day(X).

3. visit_mom(X).

4. visit_mom(X). provided you have changed the rule with this: visit_mom(X) :- no_office(X) , take_leave(X).

5. define a new rule working_day(X)to detect the days that are not holidays.

a. I can visit my mom every day.

b. I can visit my mom if I have no office.
