请问一道prep题目

Glaciers form when the snow, sleet, and hail that fall in a given climatic region exceed the amount capable
of being lost through evaporation or melting.
A. the snow, sleet, and hail that fall in a given climatic region exceed the amount capable of being
B. a given climatic region's fallen snow, sleet, and hail exceeds the amount able to be
C. the amount of snow, sleet, and hail that falls in a given climatic region exceeds the amount
D. the snow, sleet, and hail in a given region exceeds the amount able to be
E. a given climatic region exceeds the amount of snow, sleet, and hail that falls and cannot be


oa:C


不理解的是C选项中"that falls in a given climatic region exceeds the amount"that指代的应该是snow, sleet and hail. 动词为什么是单数呢？

我来搬运一下答案喏， 这个是我在GMATLA 底下评论翻到的，希望大家有所收获！同时引用Ron的原意，The OA is always the truth!
       两个并列的不可数名词作主语时，其后的谓语动词通常用复数，有时也用单数。
　　使用原则：
　　1. 如果两个不可数名词是指两样东西，则谓语动词用复数；
　　例：Coal and iron are minerals. 煤和铁都是矿物。
　　2. 如果两个不可数名词是指同一事物或同一概念，或因其紧密相关而被视作一个整体，则谓语动词用单数。
　　例：Trial and error is the source of knowledge. 反复试验是知识的源泉。

顶上。 哪位大牛给个解释啊。 不明白 C 的 “falls” 是怎么回事

我觉得falls是修饰hail的吧 肯定不说amount啊 amount不能fall呀 那就只能就近修饰hail了 我当时也因为这个把它排除了

顶起来，不懂为什么是falls啊！

我终于看懂这题了。。。我一直把form看成from了。

我个人感觉that其实指的是the amount，所以在这里为单 ...

我也觉得that指代的应该是the amount，所以fall用的是单数（the amount of ~~~~，核心还是the amount）

amount fall？这个逻辑很奇怪啊
