请问被动语态awkward的问题

在OG中经常能看到关于被动语态awkward的解释，但同时也有很多正确答案都含有被动语态。

所以被动语态在什么情况下才能判断为awlward?

请NN们总结一下

谢谢

57. In astronomy the term "red shift" denotes the extent to which light from a distant galaxy has been shifted toward the red, or long-wave, end of the light spec­trum by the rapid motion of the galaxy away from the Earth.

(A) to which light from a distant galaxy has been shifted

(B) to which light from a distant galaxy has shifted

(C) that light from a distant galaxy has been shifted

(D) of light from a distant galaxy shifting

(E) of the shift of light from a distant galaxy

in 61, OG explains that if there is clear action agent in the sentence, active voice provide more information than passive voice.

The Gorton-Dodd bill requires that a bank disclose to their customers how long they will delay access to funds from deposited checks.

(A) that a bank disclose to their customers how long they will delay access to funds from deposited checks

(B) a bank to disclose to their customers how long they will delay access to funds from a deposited check

(C) that a bank disclose to its customers how long it will delay access to funds from deposited checks

(D) a bank that it should disclose to its customers how long it will delay access to funds from a deposited check（C）

(E) that banks disclose to customers how long access to funds from their deposited check is to be delayed

In E, the use of the passive construction is to be delayed is less informative than the active voice because the passive does not explicitly identify the bank as the agent responsible for the delay.
