▶ Your Answer :
In this recommendation, the author argues that Prunty County should undertake the same kind of road improvement project that Butler County had five years ago to improve highway safety. Although this may seem convincing at first, the lack of evidence leads me to question the validity of this argument.
First, the author needs to provide solid evidence on that the speed limit of Prunty County last year was failure. The consequence may be aberrant because it was last year. Therefore it may not be continued in the long run. In addition, the result that the number of accidents has not decreased may be caused not by the speed limit, but the increase of traffic. Also, the adverse weather might be prevalent. So, It is possible that the speed limit was not failure.
Second, more specific evidence is needed on the solid conclusion that the project in Butler County should be undertaken in Prunty County. Because there might be different intrinsic conditions between them. While Butler County needed to increase lane widths and resurface rough highways, Prunty County might have wide lane enough and smooth highways.
Lastly, the author needs to supplement the argument with more evidence on that the Butler County's speed limit is not a problem. It might be still a problem since the 25% reduce of accidents might be caused not by the speed but by less traffic. Also, if the real number of accidents is marginal, the 25% reduce may not so significant.
In brief, the evidence by the author are not valid in many respects. Therefore more detailed evidence should be provided to argue that Prunty County should undertake the same project in Butler County.
