Final answer:
The reference materials provided do not contain the necessary information to determine the higher crash rate of novice drivers versus experienced drivers, so an accurate answer cannot be given.
Step-by-step explanation:
The student is asking about the relative crash rate of novice drivers compared to experienced drivers. The correct answer to this question is not provided in the information given, as the provided reference material does not include statistics on the relative crash rates of novice versus experienced drivers. Without the specific statistical data to determine the multiple by which novice drivers are more likely to be involved in crashes, it's not possible to confidently select between options a) 2 times, b) 5 times, c) 10 times, or d) 15 times. For an accurate response, additional research or a reliable source specifically addressing the crash rates of novice versus experienced drivers would be required.
