To increase reader interest in a text, authors tend to a avoid too much punctuation b create vivid and varied sentences c include as many opinions as possible d use only the most basic words

The correct answer is B. Create vivid and varied sentences

Explanation:

In texts, vivid and varied sentences imply using different types of sentences and structures and also including in them details that help the reader imagine the elements described. These two features make the text dynamic rather than monotonous and catch the reader's attention as using different types of sentences and descriptive details make the text easy to read and understand. Also, these elements are linked to coherence and cohesion in text. Therefore, it is creating vivid and varied sentences the one that an author can use to increase the reader interest.
