GMAT Sentence Correction (SC) | Re: The ancient Anasazi harvested such native desert vegetation

Hi chetan2u,

I agree that "called" is a past participle here. However, I would like to know the usage of "now". if we don;t use "now and just uses the sentence as "commonly called wild spinach" then also it will be correct.

But in this modifier we are using 2 word "Now"- Present tense
Called -> Past
