Which of the following represent elements of an author’s style?

The elements that represent elements of an author's style are the sentence length, the language used, syntactical structure and rhetorical devices. Using rhetorical devices is a way of using  effective expression or assertive text that aims to change the reader's mind or make the reader support the author's point of view. Sentence length is important because reading long convoluted sentences is off-putting to the reader. If the sentence structure is too short, however, it causes a stilted flow and the reader won't enjoy reading what the author has written either.
