Here is a question about this article: Carnival means weeks of events that bring colourfully decorated floats, contagiously throbbing music, luxuriously costumed groups of celebrants of all ages, King and Queen elections, electrifying jump-ups and torchlight parades, the Jouvert morning: the Children's Parades and finally the Grand Parade. Aruba's biggest celebration is a month-long affair consisting of festive "jump-ups" (street parades), spectacular parades and creative contests. Music and flamboyant costumes play a central role, from the Queen elections to the Grand Parade. Street parades continue in various districts throughout the month, with brass band, steel drum and roadmarch tunes. On the evening before Lent, Carnival ends with the symbolic burning of King Momo.
What is the answer to this question: How long does Aruba's biggest celebration last?
****
So... a month

The problem: Answer a question about this article:
The 45 rpm discs also came in a variety known as extended play (EP), which achieved up to 1015 minutes play at the expense of attenuating (and possibly compressing) the sound to reduce the width required by the groove. EP discs were cheaper to produce, and were used in cases where unit sales were likely to be more limited or to reissue LP albums on the smaller format for those people who had only 45 rpm players. LP albums could be purchased 1 EP at a time, with four items per EP, or in a boxed set with 3 EPs or 12 items. The large center hole on 45s allows for easier handling by jukebox mechanisms. EPs were generally discontinued by the late 1950s in the U.S. as three- and four-speed record players replaced the individual 45 players. One indication of the decline of the 45 rpm EP is that the last Columbia Records reissue of Frank Sinatra songs on 45 rpm EP records, called Frank Sinatra (Columbia B-2641) was issued on December 7, 1959. The EP lasted considerably longer in Europe, and was a popular format during the 1960s for recordings by artists such as Serge Gainsbourg and the Beatles.
What was a benefit of EPs over LPs?
****
The answer: EP discs were cheaper

Problem: Please answer a question about the following article about Estonia:
Estonia (i/stoni/; Estonian: Eesti [esti]), officially the Republic of Estonia (Estonian: Eesti Vabariik), is a country in the Baltic region of Northern Europe. It is bordered to the north by the Gulf of Finland, to the west by the Baltic Sea, to the south by Latvia (343 km), and to the east by Lake Peipus and Russia (338.6 km). Across the Baltic Sea lies Sweden in the west and Finland in the north. The territory of Estonia consists of a mainland and 2,222 islands and islets in the Baltic Sea, covering 45,339 km2 (17,505 sq mi) of land, and is influenced by a humid continental climate.
Where is Estonia located in Northern Europe?

Question: Read this and answer the question

From the 9th century, the Pecheneg nomads began an uneasy relationship with Kievan Rus. For over two centuries they launched sporadic raids into the lands of Rus, which sometimes escalated into full-scale wars (such as the 920 war on the Pechenegs by Igor of Kiev reported in the Primary Chronicle), but there were also temporary military alliances (e.g. the 943 Byzantine campaign by Igor). In 968, the Pechenegs attacked and besieged the city of Kiev. Some speculation exists that the Pechenegs drove off the Tivertsi and the Ulichs to the regions of the upper Dniester river in Bukovina. The Byzantine Empire was known to support the Pechenegs in their military campaigns against the Eastern Slavic states.[citation needed]

What year did the Pechenges attack the city of Kiev?
Answer: 968

Problem: A team led by Enrico Fermi in 1934 observed that bombarding uranium with neutrons produces the emission of beta rays (electrons or positrons from the elements produced; see beta particle). The fission products were at first mistaken for new elements of atomic numbers 93 and 94, which the Dean of the Faculty of Rome, Orso Mario Corbino, christened ausonium and hesperium, respectively. The experiments leading to the discovery of uranium's ability to fission (break apart) into lighter elements and release binding energy were conducted by Otto Hahn and Fritz Strassmann in Hahn's laboratory in Berlin. Lise Meitner and her nephew, the physicist Otto Robert Frisch, published the physical explanation in February 1939 and named the process "nuclear fission". Soon after, Fermi hypothesized that the fission of uranium might release enough neutrons to sustain a fission reaction. Confirmation of this hypothesis came in 1939, and later work found that on average about 2.5 neutrons are released by each fission of the rare uranium isotope uranium-235. Further work found that the far more common uranium-238 isotope can be transmuted into plutonium, which, like uranium-235, is also fissile by thermal neutrons. These discoveries led numerous countries to begin working on the development of nuclear weapons and nuclear power.
Who was the aunt of Otto Robert Frisch?
The answer is the following: Lise Meitner

Input: Article: Increasing state control over the oil sector, the RCC began a program of nationalization, starting with the expropriation of British Petroleum's share of the British Petroleum-N.B. Hunt Sahir Field in December 1971. In September 1973, it was announced that all foreign oil producers active in Libya were to be nationalized. For Gaddafi, this was an important step towards socialism. It proved an economic success; while gross domestic product had been $3.8 billion in 1969, it had risen to $13.7 billion in 1974, and $24.5 billion in 1979. In turn, the Libyans' standard of life greatly improved over the first decade of Gaddafi's administration, and by 1979 the average per-capita income was at $8,170, up from $40 in 1951; this was above the average of many industrialized countries like Italy and the U.K.

Now answer this question: What company's property did Libya nationalize in December of 1971?

Output:
British Petroleum
