The Story
Jurassic Park is a theme park where scientists have brought dinosaurs back from extinction. The owner invites some experts to come and visit the park to try it out before it opens to the public.
However, while the guests are enjoying a tour of the park, one of the park’s employees (Dennis Nedry) tries to steal dinosaur embryos. To escape from the park he switches off all the electric fences and the dinosaurs escape and kill and eat several people.
How could things have been different?
Dennis stole the embryos and switched off the electric fences to escape. As a result, all the dinosaurs escaped and killed and ate people.
If Dennis hadn’t switched off the electric fences, the dinosaurs wouldn’t have escaped.
