A recent survey showed that while many banks have service charges on interest-bearing and non-interest-bearing accounts with balances that are falling below a set minimum, some banks provide virtually free checking regardless of the account balance.
with balances that are falling below
whose balances fall below
whose balances fall below that of
that have balances below that of
that have balances that fall below those of
题目分析：
本题具有比较词fall below；在(A)(B)中，具有fall below关系的两者为“结余（balances）”和“最小值（a set minimum）”；在(C)(D)(E)中，具有fall below关系的两者为“结余（balances）”和“that of 最小值（a set minimum）”
选项分析：
A选项：定语从句that are falling below a set minimum的时态有误。没有理由在本句中用正在进行时，应改为一般现在时。
B选项：Correct. 本选项在语法和逻辑上均是正确的。
C选项：比较对象有误。与“结余（balances）”形成“低于（fall below）”关系的应该是“最小值（a set minimum）”，而不是that of a set minimum。
D选项：比较对象错误同选项(C)。
E选项：比较对象错误同选项(C)。

B强调的是余额低于某个值
比较对等
前：whose balances
后：一直纠结前部分，没有仔细看后部分的选项间区别，而且不要一看到比较，就下意识选 that of，这里的是a set minum最小值，不用加that of！
A， accounts with balances that are falling below a minimum，强调是余额正在下降到某个临界值的账户
B，accounts whose balances fall below a minimum，表述账户余额低于某个临界值的账户，语意更优
CDE的that 和those均没有指代
因为whose本身就不仅仅用于指代人，指代物也是可以的。因为物本身并没有所有格状态下的连词嘛~登录 或 注册 后可以参加讨论
