Which of the following most logically completes the argument?[size=9.000000pt]
A new drug, taken twice daily for one month, is an effective treatment for a certain disease. The drug now most commonlyprescribed for the disease occasionally has serious side effects such as seizures; in field tests, the new drug’s side effects, though no worse than mild nausea, turned out to be much more frequent. Nevertheless, the new drug is clearly preferableas a treatment, since _____.
选E：there is a nonprescription medication that when taken with the new drug prevents the onset of nausea.
我对题目本身没有什么异议，不过不太理解这句话的结构，后面的从句中主语是什么？作者: alzn2765 时间: 2015-6-1 13:34
there b主句
that引导定语从句修饰medication
when引时间状语从句 作者: jingliu097 时间: 2015-6-1 14:29

there b主句
是medication taken with the new drug？
所以when taken with the new drug 要跟在medication后面，如果原句改为there is a nonprescription medication that prevents the onset of nausea when taken with the new drug就不对了吧？作者: alzn2765 时间: 2015-6-1 17:42
改写会产生歧义：原来when是that引导的定语从句中的时间状语从句，改写成上面的形式之后when可能是定语从句中的时间状语从句，也可能是主句的时间状语从句，产生歧义。
