Question

Family tree — Probably the most common first example of a logic program is that involving a family tree. Give the following family tree (see attached screenshot)

a) Build a knowledge base using the predicate parent/2, which encodes a person is the parent (biological, not by marriage) of another person; male/1, which encodes a person is a male; and female/1, which encodes a person is a female.

b) Add the following rules to the knowledge base:

i. mother(X, Y), which means X is Y’s mother.
father(X, Y), which means X is Y’s father .
grandfather(X, Y), which means X is Y’s grandfather. (Note: Y can have two

grandfathers: one on the maternal side, the other on the paternal side.)
grandmother(X, Y), which means X is Y’s grandmother. (Note: Y can have two

grandfathers: one on the maternal side, the other on the paternal side.)
v. siblings(X,Y). which means X and Y are siblings.
vi. You may add aunt, uncle and cousin.

c) Test your implementation by asking queries. Write down your query and also the result.

i. Who are the siblings of Lisa?

ii. List all the grandparents of Lisa? iii. List all family members?

(Note: Same type of facts and rules should be grouped together, otherwise, you will get discontiguous error and clauses will be ignored.)

This image is a family tree depicting connections among several characters from the television series "The Simpsons" and "Futurama." It outlines the familial relationships and showcases the lineage through images and names of each character.

### Family Tree Breakdown:

1. **Top Generation:**
- **Abraham Simpson**
- **Mona Simpson**
- **Clancy Bouvier**
- **Jackie Bouvier**

2. **Middle Generation:**
- **Herb Powell** (Child of Abraham Simpson and unidentified partner)
- **Homer Simpson** (Child of Abraham and Mona Simpson)
- **Marge Bouvier Simpson** (Child of Clancy and Jackie Bouvier)
- **Patty Bouvier** (Sister of Marge; child of Clancy and Jackie Bouvier)
- **Selma Bouvier** (Sister of Marge; child of Clancy and Jackie Bouvier)

3. **Lower Generation:**
- **Bart Simpson** (Child of Homer Simpson and Marge Bouvier Simpson)
- **Lisa Simpson** (Child of Homer Simpson and Marge Bouvier Simpson)
- **Maggie Simpson** (Child of Homer Simpson and Marge Bouvier Simpson)
- **Ling Bouvier** (Child of Selma Bouvier)

### Diagram Analysis:

The diagram uses a traditional family tree structure with horizontal lines connecting spouses and vertical lines depicting parent-child relationships. The images next to each name enhance recognition by providing visual representations of the characters. Each character's placement illustrates their generational tier within the family lineage, aiding in the understanding of both immediate and extended family relationships.
