Input: Question: What was the combined ages of Victoria Azarenka and Svetlana Kuznetsova when Sventlana defeated Victoria in the quarterfinals? Passage:In the women's singles, WTA No. 49, twenty-two-year-old Estonian Kaia Kanepi defeated unseeded Petra Kvitová 6–3, 3–6, 6–1, to advance to the quarterfinals, her best result thus far in a Grand Slam tournament. World No. 4 Svetlana Kuznetsova matched her 2007 Roland-Garros performance by advancing to the quarterfinals, easily defeating sixteenth-seeded Victoria Azarenka (who had showed some good form in winning her first three matches for the loss of only six games) 6–2, 6–3. The first quarterfinal saw the highest seed remaining, Ana Ivanovic, beat tenth seed Patty Schnyder 6–3, 6–2, to reach her second consecutive semifinal at the French Open. She was joined in the afternoon by another 2007 French Open semifinalist, World No. 3 and Serbian No. 2 Jelena Janković, who dispatched nineteen-year-old Spanish qualifier Carla Suárez Navarro 6–3, 6–2, in little more than an hour.
