D. To move the reader toward the climax of the story This is the correct naswer.
Authors create tension to engage the readers. Tension is what makes a story worth reading since it will touch or move the reader’s feelings. The reader’s rational side will be set aside by his/ her emotions.
These answers are not right:
A. To introduce the characters in the story and describe where the story takes place ( This is part of the setting).
B. To reveal the author’s personal bias and opinion ( The opinion should be infered through the whole story , not jut through the tension in it).
C. To neatly tie up loose ends at the story’s close ( The tension leads to the climax not to the end of the story),
