Hi,
I read in MGMAT SC book that any subject preceded by 'any' is singular. Any of these women is suitable.
Now look at this question (sorry I could not comment there directly. ): https://www.manhattanprep.com/gmat/foru ... -t485.html
Isn't option b out because predecessors is plural and 'any of theirs' is singular? Shouldn't it be 'olden than their supposed' instead?
