我的理解是，首先，有as when的组合，我在逻辑里揪出了两个例子（兴奋不已啊！）。
21.    The initial causes of serious accidents at nuclear power plants have not so far been flaws in the advanced-technology portion of the plants. Rather, the initial causes have been attributed to human error, as when a worker at the Browns Mills reactor in the United States dropped a candle and started a fire, or to flaws in the plumbing, exemplified in a recent incident in Japan. Such everyday events cannot be thought unlikely to occur over the long run.
19.    The charge made above against alternative medicine is most seriously weakened if it is true that
(A) predictions based on orthodox medicine have sometimes failed, as when a patient has recovered despite the judgment of doctors that an illness is fatal
(B) alternative medicine relies on concepts of the body and of the nature of healing that differ from those on which orthodox medicine is based
(C) alternative medicine provides hope to those for whom orthodox medicine offers no cure
(D) a patient’s belief in the medical treatment the patient is receiving can release the body’s own chemical painkillers, diminish allergic reactions, and promote healing
(E) many treatments used for a time by orthodox medicine have later been found to be totally ineffective
其次，as肯定是连词，意思是“正如”，when作副词。加在一起，结合这三个例子，“as when”的意思可以理解为“正如当…的时候。”

从逻辑意思上并非假设关系。
C中
superficial if the three major networks all
意思是“如果。。。，则可能肤浅”
言外之意是“如果不同时播同一个东西就不肤浅”
显然不如E好。
