套路出来了果然比较好写，终于再次进入了30min大关，以后的任务就是争取增加篇幅。当然， 这篇逻辑上可能落了主要的点，希望大家指点。
我的提纲：
1.两条路的使用情况可能不同。
2.使用的时间短不代表用的少，跟交通状况有关。
3.没有Good Intentions的变化情况，无法判断Appian的变化就是占优势的。
Argument
题号：新GRE 170
题目：The surface of a section of Route 101, paved just two years ago by Good Intentions Roadways, is now badly cracked with a number of dangerous potholes. In another part of the state, a section of Route 40, paved by Appian Roadways more than four years ago, is still in good condition. In a demonstration of their continuing commitment to quality, Appian Roadways recently purchased state-of-the-art paving machinery and hired a new quality-control manager. Therefore, I recommend hiring Appian Roadways to construct the access roads for all our new shopping malls. I predict that our Appian access roads will not have to be repaired for at least four years.
写作要求：Write a response in which you discuss what questions would need to be answered in order to decide whether the recommendation is likely to have the predicted result. Be sure to explain how the answers to these questions would help to evaluate the recommendation.

The author recommends in this argument that they should hire Appian Roadways to build the access roads for all their new shopping mall, which could result in avoiding repairing for at least four years. While the author seems confident in his contention, his reasoning lacks answering certain questions after a close scrutiny.
First off, a threshold problem lies in the comparing between the extent of damage of Route 101 and that of Route 40. The author omits to inform us the frequency of transportation on the roads, which could cast doubts on the soundness of this piece of information. Route 101 would be certainly more damaged were it more trampled by more trucks, in which case the contention would lose its validness even though the two routes are of uniform quality. Thus the predicted result of Good Intentions Roadways being unreliable might be false due to a lack of evidence.
Moreover, even if the two routes are provided with evidence of similar frequency of use, there exists possibility of changed conditions owing to different time of constructing the two routes. We can extract from the argument that Route 101 was built two years ago, while Route 40 was built four years ago, of which the assumption made by the author that the less years put into use, the less frequency of use of a route is invalid. In effect, Route 101 could be built in demand of increasing traffic jams, observed more often than not four years ago, while Route 40 might be built out of private benefits, incurring fewer cracks from fewer trucks running on it, for instance. In this case, the author’s prediction would surely fall apart.
Besides, conceding that the foregoing questions may be overlooked for the time being, the fact of Appian Roadways purchasing state-of-the-art paving machinery as well as hiring a new manager is not even relevant to the demonstration of the quality of Appian being compared with that of Good Intentions, for a lack of information of the change in the latter. If Good Intentions have purchased more machineries of the same kind and substitute its manager with a more qualified one, Appian is no threat to Good intentions in the field of construction of roads any more.
In retrospect, the author’s prediction would not come to reality at all, unless he could answer to the question discussed above: the frequency of the use of both routes, the traffic conditions during the last four years, and the change in Good Intentions Roadways pertaining to managers and machineries other than that in merely Appian. Only by solving this ambiguous problems could the author announce a more convincible prediction unequivocally.
