number - 用于可数对象+可数名词；
amount - 用于不可数对象+集合名词；
·The number of students this year is increased.(注意the number of / a number of的区别：the number of + 复数名词 + 单数谓语动词；a number of + 复数名词+复数谓语词)
在结构上as引导从句表原因，with表伴随
C correct
d选项错在它的状语重心space debris & satellites所以就相当于伴随着这两个东西，那就不对了，而c选项是因为一整件事情。
amount不可数 numbers可数
as表示因为 卫星是可数的 需要用number
Because debris is not a countable noun, it must be described as an amount;
satellites are countable,so they must be referred to as a number, not an amount.
D.主要的错误the number of satellites前面没有increasing的修饰， This leaves the function of and the
number of satellites uncertain and confusing.
D increase
the amount of 修饰不可数；the number of 修饰可数名词；所以AB❌
D选项with 后面引导两个由and连接的并列名词成分，而两者前的修饰词continually increasing 要分别有，才能保持平行结构；
E选项：句子冗杂，不直接，让人迷茫
D为什么不对啊
and前后不平行
increasing定语就近修饰，只修饰了amount，没有修饰number，意思不对
as从句表原因，with引导短语还是句子都是伴随，在语义上就不对

if you've got a fraction of NOUN or a percentage of NOUN, you retain the singular/plural nature of NOUN.
so, since "students" is clearly a plural noun, so is "x% of students". since "precipitation" is clearly a singular noun, "50% of the precipitation" would also be a singular noun.
