Question

The election of 2008 was historically significant for women because
there were potentially two women on the final ballot.
a third-party female candidate made a strong showing.
women outnumbered male candidates for the Senate.
women outnumbered male candidates for the House.

Answer 1

"there were potentially two women on the final ballot."

Reason: In 2008 Hillary Clinton was a major contender for the Democratic presidential nomination and John McCain chose Sarah Palin as his running mate, so it was possible for two women to appear on the general‑election ballot (had Clinton won the Democratic nomination). The other options are not accurate for 2008.
