答案是 E. perhaps none was more concentrated than
为什么是过去时啊？ 虽然说，这些tides of immigration 都是过去发生的事情 但是那个wave比其他的tides 更加集中是不仅仅过去还有现在也是正确成立的事情啊 用现在时不也可以吗？
这里的语法规则是什么呀？
补充：为了让句子更易懂，调整一下带入正确答案后句子的顺序： Perhaps none of all the vast tides of migrations that have swept through history was more concentrated than the wave that brought 12 million immigrants onto American shores in little more than three decades. 把各种定语去掉，就变成了： Perhaps none was more concentrated than the wave.
