Which of the following, if true, helps resolve this paradox?

1. Most drivers substantially reduced their speed in response to the new limits, producing both safer roads and fewer violations.
2. Accident-reporting requirements were tightened just after the new limits took effect, expanding the set of incidents officials were obligated to record.
3. The city assigned a substantially larger number of police officers to patrol the affected streets throughout the period in question.
4. Many of the traffic accidents in the city occur late at night, on poorly lit roads where driver visibility is unusually low.
5. The fines levied for exceeding the speed limit were doubled at the very same time that the lower speed limits were introduced.
