Unlike
emergency calls that travel through regular telephone lines, where they thus
automatically inform the operator of the location and phone number of the
caller, cellular calls require emergency operators to determine the location of
the caller

phone number of the caller, cellular calls require emergency operators to
determine the location of the caller

number of the caller, cellular calls require emergency operators to determine

number of the caller, the location of the caller on a cellular phone has to be
determined by the operator


    

(D)

number of the caller, emergency operators have to determine the location of the

with high wheels capable of crossing rutted roads, muddy flats, and the
nonroads of the prairie and they had a floor curved upward on either end so as
to prevent
cargo from shifting on steep grades.

此题仅一步就可以选出正确答案。unlike后面必须马上说出来谁干什么了,而不允许让接收人琢磨,换句话说,凡是逗号后面没有接名词noun,而是代词pronoun的,必错!此原则适用95%GMAT考题。

AB排除过程参照上题
C那个with恶心,参照上题也可干掉
DE开比,发现E so that it的这个代词又得琢磨,明显不爽,干掉,填D。
此题做完

 
答案是D,但是D的结构是xxx had A1 capable of crossing B1, B2, and B3, and A2 that xxxxx.
