What was less visible then,however,were the new,positive forces that work against the digital divide.
为什么前面用was而后面用were,请大神帮忙分析一下句子结构含义。。
(我们20年前就做过演讲).......只不过(however)当时不清楚的是(What was less visible then)那些新的、积极的抵制数字化分界的力量(were the new,positive forces that work against the digital divide.)
本回答被网友采纳为什么后面要用were?
