Their study found that theobromine,found in cocoa,was nearly a thirdmore effective in stopping coughs than codeine,which was considered the bestcough medicine at present.中,which的先行词是theobromine,还是codeine?为什么

答案

我觉得是codeine
原因有二,
一、逻辑意思,全文的中心高频词肯定是theobromine,一种新发现的药,为了介绍他的药效,用codeine对比,所以应显示codeine的地位,即which（codeine） was considered the bestcough medicine at present
二、习惯用法.一般来说,老外绝对是把现行词放在定语从句的前面.这样简单,不易混淆.
