Final answer:
The question about the percentage of recent graduates who read exactly one book cannot be answered without additional specific data regarding the number of graduates and how many read one book.
Step-by-step explanation:
The original question asking about what percent of the recent graduates read exactly one book does not provide sufficient data for a direct answer. The information given in the references does not contain specific details about the reading habits of recent graduates regarding the exact number of books they read. To find a percentage, one would typically need information on the total number of graduates in the survey and the number that read exactly one book. Without this data, the question cannot be answered accurately.
