story: (CNN) -- Samantha Stosur stopped Caroline Wozniacki from clinching the year-end women's No. 1 tennis ranking with a shock 6-4 6-3 victory at the WTA Championships in Qatar on Wednesday night. 

The Australian romped to her second straight victory in the Maroon Group, following her revenge win over French Open champion Francesca Schiavone on Tuesday. 

The Roland Garros runner-up's kick serve was a potent weapon against Wozniacki, with the triumph giving the 26-year-old every chance of reaching the semifinals ahead of her final group match against Russia's Elena Dementieva on Thursday. 

It was her second victory over a top-ranked player this year, having beaten Serena Williams on the way to reaching the final in Paris. 

The fifth seed fired 26 winners to Wozniacki's 14, and could afford to serve two double-faults in the deciding game before the Dane returned a backhand long on her first match-point. 

Wozniacki, who thrashed seventh seed Dementieva on Tuesday, will next take on Italy's Schiavone on Thursday. 

Kim Clijsters, who won the $4.5 million season-ending event in 2002 and 2003, earlier triumphed in her opening White Group match 6-2 6-3 against fellow former No. 1 Jelena Jankovic despite serving 10 double-faults. 

The Belgian, returning to action after having a mole cut off her foot, broke Jankovic to love in the first game of the match and then again in the seventh. 

The three-time U.S. Open champion was less impressive in the second set but had enough to see off the Serbian, who is struggling with illness in the oppressive heat in Doha. , question: Who was Stosur's final group match against?
answer:
Elena Dementieva


question:
story: The Crimean War was a military conflict fought between October 1853 – March 1856 in which Russia lost to an alliance of France, the United Kingdom, the Ottoman Empire, and Sardinia. The immediate cause involved the rights of Christian minorities in the Holy Land, which was controlled by the Ottoman Empire. The French promoted the rights of Catholics, while Russia promoted those of the Eastern Orthodox Christians. The longer-term causes involved the decline of the Ottoman Empire and the unwillingness of the United Kingdom and France to allow Russia to gain territory and power at Ottoman expense. It has widely been noted that the causes, in one case involving an argument over a key, have never revealed a "greater confusion of purpose", yet led to a war noted for its "notoriously incompetent international butchery." 

While the churches eventually worked out their differences and came to an initial agreement, both Nicholas I of Russia and Napoleon III refused to back down. Nicholas issued an ultimatum that the Orthodox subjects of the Empire be placed under his protection. Britain attempted to mediate, and arranged a compromise that Nicholas agreed to. When the Ottomans demanded changes, Nicholas refused and prepared for war. Having obtained promises of support from France and Britain, the Ottomans officially declared war on Russia in October 1853., question: What two people didn't?
answer:

Nicholas I of Russia and Napoleon III
