QUESTION TWO
You are required to come with a Prolog program for an extended family. It stores basic facts
about the individuals that are part of the extended family, and some of the basic relationships
between individuals in that family. It should also have rules that allow the derivation of new
knowledge from the knowledge base. Below is a partial listing for a knowledge base on family
relationships.

gender (male or female)
age (in years)
height (in inches, feet, or centimeters)
mother’s father;
brother’s sister;
husband’s wife.
You may add other properties that you find relevant or interesting (e.g. weight, hair color, odd
habits …). You can also add other relationships such as fiancé, friend, business partner,etc., but it
is probably better to keep it simple. Your family should span at least 15 individuals over three or
more generations; if necessary, you can add fictional individuals. Each individual must have at
least one relationship, and on average each individual must have at least two instantiated
properties.
