a given climatic region's fallen snow, sleet, and hail exceeds the amount able to be
the amount of snow, sleet, and hail that falls in a given climatic region exceeds the amount
the snow, sleet, and hail in a given region exceeds the amount able to be
a given climatic region exceeds the amount of snow, sleet, and hail that falls and cannot be
题目分析：
本题中可以发现比较词exceed，其连接的两者需要在语法和逻辑上保持的对等。能产生“超过（exceed）”关系的两者一定要对等，即“数量”超过“数量”。而不是能是“雪”超过“数量”，可以排除(A)(B)(D)(E)，答案为(C)。
选项分析：
略
请问C选项为什么是that falls而不是that fall呢？that 从句应该是修饰snow, sleet and hail吧？如果有个F选项是把C的falls 改成fall,会不会更好呢？
修饰的是amount
fall修饰的是snow, sleet, and hail，都是不可数名词
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。
