Final answer:
Option (D) does not help resolve the discrepancy between the safety report and the city public safety records.
Step-by-step explanation:
The option that does not help resolve the apparent discrepancy between the safety report and the city public safety records is (D) Because the city's seat belt laws have been so rarely enforced, few drivers in the city have complied with them.
This option does not help resolve the discrepancy because it suggests that the seat belt laws have not been effectively enforced, which could be the reason why the number of traffic deaths per year has remained the same despite the existence of the laws.
By contrast, options (A), (B), (C), and (E) all present possible explanations for the discrepancy between the safety report and the city public safety records.
