the audience for which they are writing.

Explanation:

It is important for writers to tailor their writing according to the people to which they are directing their work. This is called an audience. If the author wants to write for children, then he needs to use simple words, lots of action, and short sentences. If the author intends to write a story for an adult, then the text should have more complexity. Regardless of the content and preferences of the author, it is important that he adapts his writing for the audience, as this will make it more likely for the reader to be interested.
