PROBLEM: After World War II, two new competing formats came onto the market and gradually replaced the standard "78": the 33 1⁄3 rpm (often just referred to as the 33 rpm), and the 45 rpm (see above). The 33 1⁄3 rpm LP (for "long-play") format was developed by Columbia Records and marketed in June 1948. RCA Victor developed the 45 rpm format and marketed it in March 1949, each pursuing their own r&d in secret. Both types of new disc used narrower grooves, intended to be played with smaller stylus—typically 0.001 inches (25 µm) wide, compared to 0.003 inches (76 µm) for a 78—so the new records were sometimes called Microgroove. In the mid-1950s all record companies agreed to a common recording standard called RIAA equalization. Prior to the establishment of the standard each company used its own preferred standard, requiring discriminating listeners to use pre-amplifiers with multiple selectable equalization curves.

SOLUTION: What two formats replaced the 78?

PROBLEM: In Ukraine, Lviv and Kiev celebrated Ukrainian Independence Day on January 22, 1989. Thousands gathered in Lviv for an unauthorized moleben (religious service) in front of St. George's Cathedral. In Kiev, 60 activists met in a Kiev apartment to commemorate the proclamation of the Ukrainian People's Republic in 1918. On February 11–12, 1989, the Ukrainian Language Society held its founding congress. On February 15, 1989, the formation of the Initiative Committee for the Renewal of the Ukrainian Autocephalous Orthodox Church was announced. The program and statutes of the movement were proposed by the Writers Association of Ukraine and were published in the journal Literaturna Ukraina on February 16, 1989. The organization heralded Ukrainian dissidents such as Vyacheslav Chornovil.

SOLUTION: What is commemorated on January 22 in Ukraine?

PROBLEM: In the Treaty of Fontainebleau, the Allies exiled him to Elba, an island of 12,000 inhabitants in the Mediterranean, 20 km (12 mi) off the Tuscan coast. They gave him sovereignty over the island and allowed him to retain the title of Emperor. Napoleon attempted suicide with a pill he had carried after nearly being captured by the Russians during the retreat from Moscow. Its potency had weakened with age, however, and he survived to be exiled while his wife and son took refuge in Austria. In the first few months on Elba he created a small navy and army, developed the iron mines, and issued decrees on modern agricultural methods.

SOLUTION:
In which treaty was Napoleon exiled?
