GWD的语法题：
1.Minivans carry as many as seven passengers and, compared with most sport utility vehicles, cost less, get better gas mileage, allow passengers to get in and out more easily, and have a smoother ride.


A.Minivans carry as many as seven passengers and, compared with most sport utility vehicles, cost less,
B.Minivans, which carry as many as seven passengers, compared with most sport utility vehicles, they cost less,
C.Minivans carry as many as seven passengers, in comparison with most sport utility vehicles, and have a lower cost, they
D.Minivans, carrying as many as seven passengers, compared with most sport utility vehicles, cost less,
E.Minivans, which carry as many as seven passengers, compared with most sport utility vehicles the cost is lower, and they

答案是D，请问E有什么问题？我觉得D有run-on的问题喔，cost less, get better, allow...

2.A new hair-growing drug is being sold for three times the price, per milligram, as the drug’s maker charges for another product with the same active ingredient.

1. as
   
2. than
   
3. that
   
4. of what
   
5. at which
   
   答案是D，我想问一下C选项有什么问题？指代不清？如果抛开这道题，three times 后面可不可以跟that/those 这类指代词呢？

第一个题目应该选择A，D是错误的

第二个题目我选择that，这里that是定语从句

选择what的话就成了the price of the price了，what只能指代价格，charge for已经说明了

两道题目答案应该都是错误的，你好好check下是不是自己看错了，要么就是答案错误了

谢谢楼上，这个是GWD的题目，答案没看错...
第一题that是定语从句引导词吗？
第二题请问A又是什么结构呢？各个选项如何排除？

好象第二题在新prep里面也有,答案是that, 但是我好象也见过, 答案是at which 的. 重要要看charge 这个词的用法吧,是应该用 charge how much for something 还是charge for something of something. 求指教
