应该是这样理解的：人们不要下一子就学会用火的,而是通过长时间的积累,取得无数的进步.后面那个 offset by regressive periods 是修饰 advances 的,意思是由逐渐减少的周期来取得进步.（或者说：用越来越少的时间取得下一次的进步）汗,这个思维太难转变了,自己明白了也很难解释清楚.
另外补充一句,我也是曾经去考过SAT,可惜家里不支持我留学啊.

这句话的意思是：人类并不是一下子就学会使用火的，而是慢慢学会。这期间经历了无数充满曲折的进步。offset是抵消的意思，前面是进步（advances），那么只能被退步抵消，选项中也就只有regressive。这也与前面的slowly契合。
