In Michael Crichton's "Jurassic Park," the characters rely on Grant's expertise to ensure the safety of the children in a dangerous environment. His background as a dinosaur expert positions him as the ideal person to navigate the challenges posed by the park's genetically engineered dinosaurs.

This highlights a key theme in the story: the importance of knowledge and expertise in crisis situations. Grant's qualifications not only provide reassurance to the kids but also emphasize the underlying tension between human ingenuity and the unpredictable nature of the recreated prehistoric world.
