我今天做了GWD30，有两道语法题没有搞明白，请各位帮忙解答，谢谢！

Q29.Researchers agreed that the study of new treatments for heart attack patients was extremely important but more research was needed to determine that balloon angioplasty preceded with ultrasound was or was not any better for heart attack patients than the balloon procedure by itself.

1. more research was needed to determine that balloon angioplasty preceded with ultrasound was or was not any better for heart attack patients than
2. more research was needed for determining whether or not balloon angioplasty preceded by ultrasound is any better for heart attack patients than is
3. that more research was needed to determine whether balloon angioplasty preceded by ultrasound is any better for heart attack patients than
4. that more research was needed to determine that balloon angioplasty preceded with ultrasound was any better for heart attack patients than
5. that more research was needed for determining that balloon angioplasty preceded by ultrasound is or is not any better for heart attack patients than is

参考答案选B，我自己选了C。其实，我觉得B的whether or not的表达是不对的，因为whether本身就有是否的意思，不需要加or not的，但是为什么要选B？还有为什么C不对？

Q41.Elk now live almost solely in the Rocky Mountains, which would make it seem that elk are mountain dwellers, while they once ranged over virtually all of the continental United States except for a small strip in the extreme Southwest.

1. Elk now live almost solely in the Rocky Mountains, which would make it seem that elk are mountain dwellers, while
2. The fact that elk now live almost solely in the Rocky Mountains would make it seem that they are mountain dwellers, but
3. It would seem that elk would be mountain dwellers because of their living now solely almost in the Rocky Mountains, but still
4. Now living almost solely in the Rocky Mountains, it would seem that elk were mountain dwellers, although
5. It seems that elk would be mountain dwellers from the fact that they now live solely almost in the Rocky Mountains, since

参考答案选A。但是如果按照修饰就近原则，A选项的which从句修饰Rocky mountains的话，句子是说不通的, which从句应该是修饰Elk now live almost soley in the rocky mountains这种行为，但是非限定从句能修饰这个句子吗？另外，B为什么不对？

我自己选的也是C和B，

对于第一题，B确实有LZ所说的问题，但是看了一下前人的讨论，C的第二个that有歧义，还是有道理的，算是争议题吧。

第二题我觉得就是B拉。

谢谢！请问你没有没第一题相关讨论的连接？因为我查到的GWD语法讨论区里面的题号好像和我在做练习的题目对不上号。很奇怪，数学题也是这样~~

找不到以前讨论的衔接啊。。c的第二个that怎么有歧异了？
