3. which term describes the way an author writes a text?\nstyle\naudience\ngenre\npurpose

Brief Explanations:

To solve this, we analyze each option:

• "style" refers to the author's unique way of writing (word choice, tone, structure, etc.).
• "audience" is the intended readers, not the writing method.
• "genre" is the category of the text (e.g., fiction, non - fiction), not the writing style.
• "purpose" is the author's reason for writing (to inform, persuade, etc.), not the way of writing. So "style" is the correct term.

Answer:

A. style
