In order to lessen the risk of accidents caused by careless driving and jaywalking at a busy intersection, the town of Colvin plans to install electronic equipment for monitoring and recording the traffic at this intersection during the morning and evening rush hours. Detailed information about this plan has been published in local papers, announced on the radio, and sent directly to every home in and around Colvin.
Which of the following pieces of information would be most helpful in predicting how well the plan described above will work?
(A) The percentage of people living in and around Colvin who have been involved in accidents at the intersection.
(B) The opinion of the plan held by the majority of people living in Colvin.
(C) The speed limit for the stretch of road on which the intersection is found.
(D) The percentage of cars that drive through the intersection that are involved in accidents.
(E) The percentage of drivers who drive through this intersection that live in and around Colvin.

(C) The speed limit for the stretch of road on which the intersection is found.
(D) The percentage of cars that drive through the intersection that are involved in accidents.
(E) The percentage of drivers who drive through this intersection that live in and around Colvin.
Correct Answer: E
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.

Hi hdwnkr,
Premise 01: To reduce accidents (due to careless driving & Jaywalking) monitoring equipment planned to be installed
Premise 02: Information about this plan would be published and transmitted through appropriate medium to "LOCAL" population
Please note carefully the keyword I have highlighted.
This is evaluate the argument sort of question.
Answer choice E is correct because:
- If the number of driver passing through the mentioned busy junction not residing LOCALLY then the people driving through would not be aware of plan:
Result: Plan could fail
- If the number of driver passing through the mentioned busy junction residing LOCALLY then the people driving through would be aware of plan:
Result: Plan could succeed
Also note that in evaluate the argument questions you can check the answer choice by proving two polar opposite choices.
Hope it helps!

I go with option E. Reason:
A -- We cannot help predict the success of the plan with the % or Colvin residents who have already been involved in accidents.
B -- Opinion cannot be used to predict. We need data.
C -- The speed limit for the stretch of the road cannot be used to predict anything.
D -- Again we cannot use this information.
E -- Yes, if the percentage of drivers who drive through the intersection is known then by broadcasting this plan to the local residents we could predict the success of the plan.
