求助 【】内的句子的 ——主语是啥?谢谢啦.
some researchers have come up with the finding that influentials have far less impact on social epidemics than【 is generally supposed.】

influentials我怎么觉得是impact呢?正在思考中,请稍等,我还原整句
influentials have far less impact on social epidemics than influentials is generally supposed on the social epidemics before,
就是influentials 吧,influentials 和impact不是同一个意思吗?以我看来,应该是influentials 作为主语,influentials 也是从句主语不是吗?than作为连词,后面如果主语相同可以省略.好像有点道理啊_____xiexie其实我没过than 后面就直接is的,感觉好像错的,刚才搜了一下,还有这种用法,感觉怪怪的
