Can Someone walk me through the answer. It is E.
My own set of words were (i) give credence (ii) concept.
;:
My Reasoning:
Since 2nd part of the sentence starts with even and it says: that even the more central idea was more or less a theoretical thing (concept) , so he did not pay heed/attention to the idea of race (gives no credence).
Any help would be appreciated since old gre walkthroughs have been put down.
Thanks.
