Hi Community,
Please see my question below:

That the new managing editor rose from the publications soft news sections to a leadership position is more of landmark in the industry than her being a woman.

a. her being a woman
b. being a woman is
c. her womanhood
d. that she was a woman
e. that she is a woman

correct ac: "e"

Is the reason for E as a correct ac b/c we need some sort of pronoun or preposition after "than" as we see after "more"?

Thanks in advance for your help.
