Question Stats:

Many small roads do not have painted markings along their edges. Clear edge markings would make it easier for drivers to see upcoming curves and to judge the car's position on the road, particularly when visibility is poor, and would therefore seem to be a useful contribution to road safety. However, after Greatwater County painted edge markings on all its narrow, winding roads the annual accident rate along these roads actually increased slightly. Which of the following if true, most helps to explain the increase in accident rate?
A. Greatwater County has an unusually high proportion of narrow, winding roads.
B. In bad weather it can be nearly as difficult for drivers to see the road as it is at night.
C. Prior to the painting of edge markings, Greatwater County's narrow, winding roads already had a somewhat higher accident rate than other Greatwater County roads.
D. Many of the accidents on narrow, winding roads involve a single vehicle veering off the road, rather than the collision of two vehicles.
E. After the markings were painted on the roads, many drivers who had gone out of their way to avoid driving on those roads at night no longer did so.

A. Greatwater County has an unusually high proportion of narrow, winding roads. - does not help, the proportion may be higher or lower but accident rate should have decreased compared to previous accident rate.
B. In bad weather it can be nearly as difficult for drivers to see the road as it is at night. - passage reads edge markings makes drivers easier to see in poor visibility.
C. Prior to the painting of edge markings, Greatwater County's narrow, winding roads already had a somewhat higher accident rate than other Greatwater County roads. - winding roads may have accident rate of 80% compared to other GC roads... but with edge markings that particular rate should decrease.
D. Many of the accidents on narrow, winding roads involve a single vehicle veering off the road, rather than the collision of two vehicles. - passage doesn't compare the type of accident
E. After the markings were painted on the roads, many drivers who had gone out of their way to avoid driving on those roads at night no longer did so. correct - drivers who were avoiding driving in bad visibility now drives more at that time

It is the resolve paradox type question.

Clear edge marking would contribute to road safety for the reasons mentioned.
But, after Clear edge marking were painted on a road, the accidents increased there. Why so OR how so?

A. Greatwater County has an unusually high proportion of narrow, winding roads.
This factor remained unchanged after or before the painting.

B. In bad weather it can be nearly as difficult for drivers to see the road as it is at night.
It is mentioned that these markings assist drivers to avoid accidents in poor visibility. It couldn't possibly have caused a negative result. Furthermore, this is also a constant factor in both scenarios.

C. Prior to the painting of edge markings, Greatwater County's narrow, winding roads already had a somewhat higher accident rate than other Greatwater County roads.
It draws a comparison between narrow roads AND other roads. We are concerned about narrow roads only before AND after the painting.

D. Many of the accidents on narrow, winding roads involve a single vehicle veering off the road, rather than the collision of two vehicles.
This may be true. But, passage doesn't give us any correlation between types of accident AND painting. Out of scope.

E. After the markings were painted on the roads, many drivers who had gone out of their way to avoid driving on those roads at night no longer did so.

This gives us a possible scenario where marking has an adverse effect. Earlier only 1000 people were regularly using the road at night, now 2000(some random number more than 1000) people are using the road. Greater number of cars on the road may result in more accidents.

E for me
yipeeeeeeeee
only this explains the increase is due to an increase the total increase in the no of drivers on the road........ :) :)

E for me as well. The conclusion talks about the rate. One way the rate might have increased is because of more people took the route.

Initially I thought the answer is C. After seeing the result, I realized that C, in fact, complicates the argument.
