20. As a general rule, really great novels contain A. complexplots B. universal truths C. multiple settings D. one main conflict.

The correct answer is B. universal truths.<br /><br />Great novels often contain universal truths, which are fundamental principles or realities that are common to all human beings. These truths can be about the human condition, relationships, emotions, or the nature of existence. By exploring these universal themes, novels can resonate with readers from different backgrounds and cultures, making the story more meaningful and relatable. While complex plots, multiple settings, and one main conflict can contribute to the depth and structure of a novel, it is the exploration of universal truths that often sets truly great novels apart.
