Bart has never been skiing before and decides he wants to go$.$ He goes to a ski resort that offers lessons for beginners, but also has several highly advanced $$Black Diamond$$ runs for experienced skiers. As Bart is renting equipment from Lisa, a ski instructor at the resort, he admits to her that he has never been skiing before. Lisa tells him clearly that he should take a lesson before he tries to go down any hill, and that he should stay far away from the Black Dimond runs because as a beginner, he would not be able to get down the mountain without any injury
