he KB is:

$$ If X swims and X eats algae, then X is a clownfish.

$$ If X hops and X has a tail, then X is a kangaroo.

$$ If X is a clownfish, then X is orange and white.

$$ If X is a kangaroo, then X is red$-$brown.

$($a$)(10$ points$)$ The goal is to conclude the color of an animal is orange and white. You

are also given the following facts. The pet swims and the pet eats algae. Using

these two facts and the knowledge base, use forwarding chaining to show that the

color of the animal is orange and white.

$($b$)(10$ points$)$ Using the same KB as the previous question, use backward chaining to

show that a pet that hops and has a tail is red$-$brown
