Critical Reasoning

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 those 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 the 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.


Will post OA after some discussion.

IMO E

IMO E. Waiting for the OA.

Great!!!

OA is E .. Guys could you please explain how E is correct.

A. Greatwater County has an unusually high proportion of narrow, winding roads.
This is already mentioned in the argument but question is WHY ?

B. In bad weather it can be nearly as difficult for drivers to see the road as it is at night.
We are not talking about weather here. We have to show how annual accident rate actually increased.

C. Prior to the painting of the edge markings, Greatwater County's narrow, winding roads already had a somewhat
higher accident rate than other Greatwater County roads.
Irrelevant to look at other 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.
we are not concerned about single vehicles or collision of vehicles. We are only concerned about accident rate.

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 can be the reason why accident rate actually increased because the drivers who could have avoided the accident by going out of their way no longer did so because of the fear of collision with other cars, as painted markings are considered for road safety.
