这个英文句子不是病句么,that后面不是定语从句?请指出主语谓语,
Approved April 24,1800,the act of Congress that made provision for the
removal of the government of the United States to the new federal city,
Washington,D.C.,also established the Library of Congress.

主语the act of Congress + 定语从句that + 谓语 established + 宾语 the Library of Congress谢谢,请问also是不是有点多余?
