Of all the vast tides of migration that have swept through history, may be none is more concentrated as the wave that brought 12 million immigrants onto American shores in little more than 3 decades.
I understand this is an idiom + verb question and it should be more X than Y.
I have a question about the verb tense usage here.
the answer uses "was" so,
perhaps none was more concentrated than.
Why should we use was, when we are using present perfect "have swept". why can't it be ,
none "is" more concentrated than the wave...
this answer choice was not there in the choices, but I would like to know why "was" is correct.
Can you not use simple present after using present perfect?
