乌克丽丽1995

The rate at which a road wears depends on various factors, including climate, amount of traffic, and the size and weight of the vehicles using it. The only land transportation to Rittland’s seaport is via a divided highway, one side carrying traffic to the seaport and one carrying traffic away from it. The side leading to the seaport has worn faster, even though each side has carried virtually the same amount of traffic, consisting mainly of large trucks.

Which of the following, if true, most helps to explain the difference in the rate of wear?

A.   The volume of traffic toand from Rittland’s seaport has increased beyond the intended capacity of thehighway that serves it.

       B.   Wear on the highway that serves Rittland’sseaport is considerably greater during the cold winter months.

       C.   Wear on the side of the highway that leads toRittland’s seaport has encouraged people to take buses to the seaport ratherthan driving there in their own automobiles.

       D.   A greater tonnage of goods is exported fromRittland’s seaport than is imported through it.

       E.   All of Rittland’s automobiles are imported byship.

为什么选D呢？公路的话不是无论出口还是进口都是一样的吗TAT

D   Correct. This suggests that the many trucks visiting the seaport tend to be more heavily laden with goods when traveling on the side of the highway leading to the seaport than when returning on the other side. The resulting difference in the trucks’ weight when traveling on the two sides could explain the different rates of wear.

想不明白呀求助！

还有想问问看了毕出逻辑那本书，但是不知道如何运用实战呢？

书上练习的题目太少了TAT

如果是出口的货物比进口的多，那么出口的那条路损坏的更快啊

很好理解啊。 D选项的意思是Rittland港口的货物出口量比货物进口量多。 那么就意味着有更多的载满货物的货车从港口开出去而不是开回来。注意文中说了出口和进口的路是divided，就像高速公路一样，那么肯定去港口的路要比出港口的那一条路磨损的多啊。
