When we compare two things, we like to put them on the same background. same condition.
For the fact given above, in the same time, foundmentally, the two region have the same traffic condition, except, the speedlimit is improved in one, and the other keep the same. So we can get the result that the reason of the difference is that the improved speed limit. And also the change will give some other inconvinent to the people there. For example, the people will not familiar with the change, have some problem in handle the speed.
So, what I think is that the citizen should show the government the statistic number of the difference. Argue with them. Comments:
This response is fundamentally deficient as a critique for two reasons:
-- although the writer has relied heavily on the language of the topic,it is clear that the writer has no real control of language, and
-- there is little or no evidence of the writer's ability to develop an organized response.
