In order to lessen the risk of accidents caused by careless driving

I pick E.

The premise states that the information about the plan is only going to be sent to houses in and around Colvin. For this plan to work, those people who receive the information have to be relavant to the situation. In other words, they have to be driving through that particular intersection in order to care about the information that is been sent to them.

E as the correct choice has to include the drivers living in and around Colvin who drive through this intersection. A is limited in its scope by including only the drivers involved in accidents.

Although the option I selected was correct, it was a fluke.

My understanding of the argument:
1. There is an intersection where a lot of accidents take place.
2. City plans to install equipment to monitor the traffic in the morning and evening.
3. This plan of monitoring and recording stuff is supposed to stop accidents.

We need to select an option that supports the fact that the plan will work. And then the options are five numbers - speed limit, percentages. Can someone please explain how these numbers would help towards the plan to be successful?

I was originally confused by D because I interpreted it to mean that we would have the future statistics. Clearly the future stats would be most useful in determining success. But D is actually only referring to current stats which isn't relevant. What if it's 100%? What if its 1%? It doesn't tell us anything.

Need to more emphasize on the distribution of detailed plan around Colvin...2 best contenders are A and E while in A scope is limitted.

Hello GMATNinja VeritasPrepKarishma,

In option E, how will it "lessen the risk of the # of accidents due to jaywalking and careless driving". I somehow can't logically relate how information from Option E will help to solve the problem stated in the arguement

Request your help. Thanks

I think a, d and e are strong contenders. Could you please xplain reasoning behind the correct choice e

(A) The percentage of people living in and around Colvin who have been involvedd in accidents at the intersection.
-Doesn't help
(B) The opinion of the plan held by the majority of people living in Colvin.
-Doesn't matter
(C) The speed limit for the stretch of road on which the intersection is found.
-Could be, but we need more elaboration of this point, so this isn't it.
(D) The percentage of cars that drive through the intersection that are involved in accidents.
-Percentage could help monitor repeat offenders, but doesn't help the plan.
(E) The percentage of drivers who drive through this intersection that live in and around Colvin.
-The plan is announced to the public. If a large percentage of people from out of town drive through this intersection, then the plan won't work because those out of town drivers wouldn't be aware of the announcement. So, if percentage is low, plan will work. If not, it won't.

now what if all this plan/detailed info (announced on radio, local news papers ....) is not received by the majority of the drivers in Colvin ( drivers who don't live in the city but only commute for work for example)
the plan won't be received by the majority of the drivers and thus will fail to reduce the accidents .
That's what option E is all about.

VERITAS OFFICIAL EXPLANATION

The conclusion is that there will be fewer accidents as a result of the plan to install electronic equipment and to let the residents of Polvin know about the installations. The question asks us to choose the most relevant information in evaluating the strength of this plan. If we know the percentage of drivers who go through this intersection who are Polvinians (and thus know about the monitoring equipment), we can say the plan will work (if the percentage is high) or won't work (if the percentage is low). Thus choice E helps us evaluate the relative strength of the argument (the plan). Choice A has it backwards; the percentage of Polvinians who pass through the intersection is not important. In answer B, the opinion of the plan by most of those living in Polvin doesn't matter. What matters is whether they'll drive differently, which you can't tell from this choice, making it incorrect. Choice C does not affect the outcome of the plan. Answer D in incorrect because whether that percentage is 1% or 50%, the only thing that matters is whether the percentage will drop.

Lets make this simple.

Installing equipment and sharing the information with residents of Polvin -> Reduce the risk of accidents caused by careless drivers

Falsification-Installing quipment and sharing info will not lead to reduction in accidents

What if, the accidents are caused by people staying out of the town

Assumption- Most accidents are caused by people of the town

Evaluate-The percentage of drivers who drive through this intersection that live in Polvin.

(A) The percentage of people living in and around Colvin who have been involved in accidents at the intersection. ->The % of people living in and around Colvin already involved in an accident won't help us predict that the plan is success or failure. If this option would have been the %age of people jaywalking then it could have been an evaluate

(D) The percentage of cars that drive through the intersection that are involved in accidents. -> Incorrect because whether that percentage is 1% or 50%, the only thing that matters is whether the percentage will drop.

(E) The percentage of drivers who drive through this intersection that live in and around Colvin. CORRECT
