6. The use of gravity waves, which do not interact with matter (in the way electomagnetic waves do, hopefully will enable)astromomers to study the actual formation of black holes and neutron stars.
b in the way electromagnetic waves do, will, it is hoped, enable
c like electromagnetic waves, hopefully will enable
d like electromagnetic waves, would enable, hopefully
e such as electomagnetic waves do, will, it is hoped, enable

答案b。不太明白原文的意思，只能看出gravity waves是不能和e-wave interact的。有谁帮忙翻一下！还有是不是在gmat只有it is hoped, 没有hopefully？

8 A majority of the international journalists surveyed view nuclear power stations as unsafe at present but (that they will, or could,) be made sufiiciently safe in the future.
d think that they will be or could
e think the power stations would or could

答案d. 对D有疑问。1。they在这里指代没有power stations清楚，有可能指代journalists。2。 will be or could好象没有would or could更平行。但E又缺that。
碰到这种情况，怎么处理？

20 Never before in the history of music have musical superstars been able to command (so extraordianry fees of the kind they do today).
b so extraordinary fees as they are today
c such extraordianry fees as they do today
答案c
但不明白为什么补出do  原文前面是superstars have been able to
在这道题中，因为选项的限制只好选c
但如果以后再碰到sb have been able to do sth. than sb 。。。 后面应该补什么呢？是than sb have, than sb can， than sb are  很困惑。

看完就糊涂了。on the basis,on the ground of , because在意思上有什么区别？
