请教一个关于多重定语从句的问题!
It was above all the French,followed closely by the Americans,who were the most passionate exporters of the invention,helping to start cinema in China,Japan,Latin America and Russia.
Q1：句子中的who指代的是法国还是美国?
Q2：是法国还是美国帮助了中日俄开创了电影事业?

Answer 1

法国.美国是其次,而主句讲的是most passionate,有唯一指代的意思.

还是法国,美国那个是插入语,补充信息用,不影响主句的意思.
