（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

我选的D 我觉得A 有问题啊。。D的表述更明确一点。。
只是我还想问一点 如果存在比较的话（有2个以上包含2个的情况下）是不是比较的部分必须保持一致，比如这道题中是不是carry那个比较和cost less 都做主句？

D选项中把Carry。。。这部分改成了从属成分，而原句中是并列成分，如果不是不存在很严重的错误，一般不要改动原句的成分，这里的变动改变了原句的意思，所以错误

我觉得A的问题也大啊。那个第一个逗号之前的and你看到了么？难道不会产生歧义么？后面那个compared 一放在这，不就破坏了并列 的成分了么？我之前下了一个GWD13那个解释，上面选的是D,答案是A。so confused.....

yidiyuehans

这个句子其实是两个并列的，第一个就是carry 和第一个 and后面的整体并列，第二就是cost, allow, and have并列；compared。。。这部分只是要给插入语，可以不用考虑，而且D选项中，在主语Minivans和谓语动词之间有两个插入成分，把主谓语隔的太远，也是不合理的

got it .thx...anyway ,A is superior to D
