A study published in the British Medical Journal showed | that women (who ate nuts more than five times a week) were about one third less likely to suffer from coronary heart disease than those (who ate no nuts at all) were.

毕老师，是这样理解么？

ｗomen +定语 were less likely to suffer than those woman +定语。 老师，这个选项哪里错了？

这道题上课讲过，想起来了…
一周吃五次以上坚果的女人跟她们不吃的时候比

句子可以理解为是women A were less likely to do C than women B were likely to do C 么？

实在不理解为什么多出来一个were?不是人比人么……句子看懂了也做不对:(

不懂，求解答
