B.It often competed against Massachusetts and other sates

D.It became a richer state than Massachusetts with faster growth.

参考答案：C

参考解析：

定位到This growth also occurred in Pennsylvania. The iron industry pushed that state along and helped it to grow even faster. 可见，宾州的铁工业让州得到了发展。A项：他有类似于马塞诸塞州的纺织工业，错误，原文没有提到他有纺织工业，B项：他经常和马塞诸塞州和其他州进行竞争，错误，原文没有提到它跟别的州竞争，C项：他的铁工业比其他州的铁工业还强，符合原文，D项：他成为一个比马塞诸塞州更富有的州，错误，文中没有提到它更富。故本题正确答案选C。
