Answer:
d. It includes a question that the reader will want to know the answer to.
Step-by-step explanation:
Suspense is created in a story when there are certain events in the story where there are unanswered questions or even some information is still left in the story. They help intensify the interest of the readers in wanting to know more about what the future scenes will reveal.
In the given excerpt from "Heart of a Samurai" by Margi Preus, the suspense is created when the question of where the third person is and who made the graves is brought up. Everyone, including the readers, would want to know the answers to these questions.
Thus, the correct answer is option d.
