Lea is small, brown and of age ripe. She likes classical music, the books of adventure and swimming. She seeks a brown man, not very tall and of age ripe.

1. Using PROLOG, express the facts above in the form of predicates.

2. It is considered that two people X and Y, of different sexes, are matched if : X is appropriate to Y and Y is appropriate to X.

X is appropriate to Y if:

X is appropriate physically to Y (height, color of hair and age of X are those which Y seeks) and,

X and Y have the same tastes regarding music, literature and sport.

Write a PROLOG program determining the matched couples. Example 1 :

| ?- match(X,Y).

X = kevin

Y = eva ? ;

X = eva

Y = kevin ? ;
