PROBLEM: Passage: In 2014, Ivanovic enjoyed a resurgence and attained a number of career-best achievements. She began the year by winning her first title in three years at the ASB Classic, defeating former world No. 1 Venus Williams in three sets before upsetting the reigning world No. 1 Serena Williams en route to her second Australian Open quarterfinal where she lost in three sets to thirtieth seed, Eugenie Bouchard. During the clay court season, Ivanovic reached her third final of the year at the Porsche Tennis Grand Prix, losing to two-time defending champion Maria Sharapova; the quarterfinals of the Mutua Madrid Open and the semi-finals of the Internazionali BNL d'Italia, defeating Sharapova for the first time since 2007 en route but was ultimately upset by Lucie Safarova in the third round of the French Open. She rebounded by winning her first career singles title on grass at the Aegon Classic before reaching the final of the Western & Southern Open (her first top tier Premier final since 2009) and thus returned to the top ten of the WTA rankings for the first time in five years as a result. In September, Ivanovic reached her sixth singles final of the year (a new career-best) at the Toray Pan Pacific Open, where she defeated Caroline Wozniacki to claim her fourth title of the season, the most titles she won in a single season.

PROBLEM: Passage: In the spring of 1902, Bulgaria, an Ottoman vassal state which was interested in acquiring Macedonia, signed a military convention with Russia. Late in the fall, Russia, supported by the United Kingdom and France, proposed to the Ottomans political reforms for the Macedonian vilayets. On 8 December, the Ottoman sultan, Abdul Hamid II, signed a decree implementing most of the reforms. In February 1903, the new Russian foreign minister, Vladimir Lamsdorf, visited Vienna and signed the so-called "Vienna Program" on Macedonian reforms. The program was substantially the same as the Ottoman decree of December. The immediate provocation of a new agreement at Murzsteg was the IlindenPreobrazhenie Uprising that broke out on 2 August. With its quick suppression, the Vienna Program lay dead. In September Tsar Nicholas II of Russia visited the Emperor Francis Joseph of Austria-Hungary at the latter's castle in Murzsteg, Austria. The two rulers put their signatures to a new memorandum, substantially identical to the Vienna Program, which called for the appointment of one Russian and one Austro-Hungarian civil agent to oversee the reform of the administration, judiciary and local gendarmerie in the Macedonian vilayets. In all these institutions Christians were to take part. After Abdul Hamid accepted the proposal in November, Russia appointed one N. Demerik as its agent, and Austria chose one G. Muller. They began their work under Huseyin Hilmi Pasha, the Inspector-General of Macedonia, in early 1904. Under the Murzsteg program, each Great Power appointed an advisory official to the Ottoman official in charge of reforming the gendarmerie in each province. Austria-Hungary appointed an advisor to the sanjak of Uskup, Russia to the sanjak of Thessaloniki, France to the sanjak of Siroz and Britain to the sanjak of Drama.
