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

E is the best option.

Evidence - small roads don't have proper edge markings. Clear edge markings will help when visibility is poor and contribute to road safety.
Conclusion - Annual accident rate increased slightly.

A. Irrelevant
B. It is mentioned in the argument that "Clear edge markings will help when visibility is poor ".
C. This doesn't support the conclusion.
D. Irrelevant
E. This option mentions that drivers avoided these roads at night earlier, but after clear edge markings were painted, drivers started using those roads(edge markings didn't help much) and hence the rate of accidents increased.

totally agree with E. Driving in the night is the primary reason for the high accident rate.

E for me too.

more people started using these roads => so there is a chance for increase in rate of accident

Ok, first I am wrong with B. now, I can explain it wrong because the weather have effects on both the before and after decision of painting edge marking. So, neutral.

(E) mean. after painting edge mark, more people drive on night than before. Make sense.

for most cr questions, such as , assumption, strengthen, weaken , evaluate and flaw questions, our success depend on our ability to criticize the argument before going to answer choice. we need to do criticization before going to answer choices.

do criticization,
why after set up markings, accident increases. there is something happen which make the marking usless.

E provides that action which make the marking unable to compensate .
