No wonder Americans who practice yoga are often well-educated, have higher-than-average household income and are willing to spend a bit more on so-called “green” purchases seen as benefiting the environment or society.
这道题错误之处是benefited改为benefiting,解析说是非谓语动词误用,benefit与它的逻辑主语green purchases是主谓关系,因此应该使用现在分词形式。我的问题是seen as做什么成分,参照解析来说benefiting是非谓语,那么seen as的宾语是谁?
