SAT语法题 08.1-16
By incorporating Pueblo figures into her strongly geometric and abstract work is why Pueblo artist Helen Hardin has had a significant impact on contemporary Native American art.
work is why 错了 为什么?

有了is why这句话就没有主语了.
By incorporating Pueblo figures into her strongly geometric and abstract work 只是一个表示方式的介词短语,介词短语是不能做主语的.
去掉is why就可以了.
