什么意思？

As early as 1647,Ohio made a decision that free ,tax supported schools must be established in every town having 50 households or more是这句哟！那里只能打那么多字。

早在1647年，俄荷俄州就作出决定,在有50户以上居民的城镇建立免费的，以税收支持的学校。

答案是a 全句的意思是：“早在1647年ohio州就做出决定，拥有50或50户以上家庭的每一个镇，都必须建立免费的由税收维持的学校。”句中in every town having 50 households or more 相当于in every town which has 50 households or more。。
