OG127 分词和从句，ets喜欢谁？？

127. In theory, international civil servants at the United Nations are prohibited from continuing to draw salaries

from their own governments; in practice, however, some governments merely substitute living allowances

for their employees' paychecks. assigned by them to the United Nations.

(A) for their employees' paychecks, assigned by them

(B) for the paychecks of their employees who have been assigned(B)

(C) for the paychecks of their employees, having been assigned

(D) in place of their employees' paychecks, for those of them assigned

(E) in place of the paychecks of their employees to have been assigned by them

把C改成....exmployees assigned应该是对的吧？

觉得ets一会喜欢从句修饰，一会喜欢分词，到底他喜欢谁呢？？

怎么这么久也没人搭理?

没有歧义时用分词更简洁,用分词有歧义时用定语从句明确修饰对象.

在這個句子中，如果省略who have been,會產生一個可能的ambiguity:

the paychecks of their employees assigned by them to the UN.

是誰被assigned?employees還是paychecks?

open to discuss

AlienX

According to 白勇's GMAT SC book, a present perfect participle(e.g. have verb-ed/having been verb-ed) canNOT modify a noun; so C is not correct.

If C becomes
for the paychecks of their employees assigned
B is still slightly better because "have been assigned" indicates that "assign" happens before "substitute".
