请找出它的语法错误
1、The trgic story of paolo and francesca was the subject of a poem and a symphony ,being popular throughout the nineteenth century .
2、Just as Ireland has produced many famous writers and the Netherlands an abundance of famous painters,(so) Finland has provided a large number of famous architects.括号中的so没有错误吗?
感谢planet 999 还有一点疑惑
being不能单纯作修饰吗 为什么要用having been呢
plant 999 好像不在

1\being popular _ having been
2\so 有错,just as 后面不能加so
用having been 是因为主句是过去式；being能单纯作修饰
