Final answer:
The film adaptation of a short story by Roald Dahl can vary from the original text due to cinematic techniques, expansion of the storyline, and altering of the plot sequence. Film adaptations often utilize unique film techniques such as special effects and non-linear storytelling. Cervantes's book is considered the first modern novel because its characters evolve throughout the story.
Step-by-step explanation:
The difference between the film version and the actual short story by Roald Dahl can be numerous and depends on various factors. When a short story is adapted into a film, filmmakers may change aspects such as the plot sequence, key characters, or settings to suit the cinematic format and possibly expand on the story to fill a feature-length movie. Such changes can include altering the ending (significant alterations), expanding the storyline, omitting characters, changing the setting, or reimagining the plot's sequence for dramatic effect.
Moreover, in adapting a novel or short story, directors and screenwriters might apply various film techniques that can significantly alter how the story is told. These can include the use of special effects, non-linear storytelling, and creative editing, which are unique to the film medium, unlike the linear and more limited technique scope of theatre or a written narrative.
As for Miguel de Cervantes's book being described as "the first modern novel," the correct answer is that the characters evolve throughout the story. The concepts of character development and a sustained narrative that extends through the entire book were innovative for the time Cervantes was writing and have since become a staple of modern novel writing.
