Answer:
A. "Hey, Jack. Are the new road maps in?"
Jack looked puzzled. "Maps, huh? Local or national?" he replied.
"National, please," Chris said with a broad smile.
Step-by-step explanation:
Based on the passage provided, we can know that Ben is quite familiar with the store "Ahab's Books". In fact, he had worked there too. But once graduation draws near, he quit to concentrate on his studies. When he asked Jack for a national map, it implies that he's planning on going out of the town after his graduation. He would have known all the places within the town as he had been a part of it this whole time. Also, the surprised and puzzled look reaction that Jack gave him when he asked for the national road map shows that even he (Jack) was shocked. The conversation between them foreshadows his plans of moving after graduation.
