Some patients who do not respond to therapies for depression may simply have received inadequate treatment, having, for example, been prescribed a drug at a dosage too low to be effective or having been taken off a drug too soon.
(A) having, for example, been prescribed a drug at a dosage too low to be effective or having been
(B) having, for example, a drug prescription that was ineffective because the dosage was too low, or being
(C) as, for example, having too low of a dosage of a prescribed drug for it to be effective, or being
(D) when they have, for example, been prescribed too low a drug dosage to be effective, or were
(E) for example, when they have a drug prescription with a dosage too low to be effective, or been
原文意思：一些病人不愿意进行抑郁症治疗可能是因为治疗力度不够，例如一个药物剂量不够或者吃的太快了
题目分析：原文有一个并列关系，就是having been prescribed or having been taken off这个并列，它故意用for example把两个having隔开让我看出来的难度大一些，A这个并列写的不错，留着。B中的 that was ineffective because the dosage was too low太罗嗦了，杀。C中的as和or后面不对应，并且it很不爽，杀。D以when开头，但后面是for example，这两个连词奇怪，for example就是后面把前面说的细一些，没有必要加when，干掉。E和D是一样的，杀！
