Answer:
Writing style is the way the author puts the story together, and the vocabulary he/she uses.
Step-by-step explanation:
Some authors will purposely write grammatically incorrectly, as it is their writing style. Some authors may repeat themselves. Some authors may organize the story to be slow at the beginning, but then have an immediate climax.
All writing styles are different, as they are the preference of the author themselves, and how they want the story to be perceived.
