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.

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

答案是：“A greater tonnage of goods is exported from Rittland's seaport than is imported through it.”

但是如果出口更多的话难道不应该是离开Seaport的那一边磨损更严重嘛？？？

想不通啊……

解决了。因为出口首先得有装满货物的truck开去seaport,然后再出口. 做题的时候忽略了这个过程，以为出口就是直接从seaport出去呢呵呵～
