The burden of maintaining the U.S. highway system falls disproportionately on the trucking industry. Trucks represent only about 10 percent of the vehicles on U.S. roads. Yet road use taxes assessed on trucks amount to almost half the taxes paid for highway upkeep and repair.
Which of the following, if true, would most weaken the argument above?
(A) The trucking industry has enjoyed record after-tax profits in three of the past four years.
(B) Because of their weight, trucks cause over 50 percent of the damage sustained by highway surfaces each year.
(C) Without an economically viable trucking industry, the cost of goods in the United States would rise significantly.
(D) Road use taxes paid by trucking companies have decreased by 3 percent over the past five years.（B）
(E) Due to years of neglect, U.S. highways today are badly in need of major repairs and rebuilding.
题目意思，尤其是红色部分看不懂，能否帮翻译一下，谢谢！
Yet road use taxes assessed on trucks amount to almost half the taxes paid for highway upkeep and repair
然而在卡车上征收的道路使用税几乎占了高速公路维护税的一半
怎么会是选B呢?我相反觉得B是STRENGTH原文结论的，因为原文说TRUCK占10%却付50%的税,那B中说的"因为他们引起了超过50%的DAMAGE".
原文的意思是觉得卡车出的钱太多了.
The burden of maintaining the U.S. highway system falls disproportionately on the trucking industry
这是原文的结论，后面说，卡车出的钱和卡车数量不成比例。后面都是EVIDENCE 来SUPPORT 这个结论的。车少，出钱多.
要WEAKEN就是WEAKEN这个结论，卡车虽然少，造成的破坏大，所以出的钱就应该和车辆不成比例。
