On December 7, 1941, Japan attacked the United States at Pearl Harbor, bringing it too into the war on the Allied side. China also joined the Allies, as eventually did most of the rest of the world. China was in turmoil at the time, and attacked Japanese armies through guerilla-type warfare. By the beginning of 1942, the major combatants were aligned as follows: the British Commonwealth, the United States, and the Soviet Union were fighting Germany and Italy; and the British Commonwealth, China, and the United States were fighting Japan. The United Kingdom, the United States, the Soviet Union and China were referred as a "trusteeship of the powerful" during the World War II  and were recognized as the Allied "Big Four" in Declaration by United Nations These four countries were considered as the "Four Policemen" or "Four Sheriffs" of the Allies power and primary victors of World War II. From then through August 1945, battles raged across all of Europe, in the North Atlantic Ocean, across North Africa, throughout Southeast Asia, throughout China, across the Pacific Ocean and in the air over Japan.
When did the attack on Pearl Harbor occur?

Input: Warsaw Pact
The Warsaw Treaty's organization was two-fold: the Political Consultative Committee handled political matters, and the Combined Command of Pact Armed Forces controlled the assigned multi-national forces, with headquarters in Warsaw, Poland. Furthermore, the Supreme Commander of the Unified Armed Forces of the Warsaw Treaty Organization which commands and controls all the military forces of the member countries was also a First Deputy Minister of Defense of the USSR, and the Chief of Combined Staff of the Unified Armed Forces of the Warsaw Treaty Organization was also a First Deputy Chief of the General Staff of the Armed Forces of the USSR. Therefore, although ostensibly an international collective security alliance, the USSR dominated the Warsaw Treaty armed forces.

Despite being headquartered in Poland, the top-ranking operatives of the Warsaw Pact were from which country?
Output: the USSR


Input: Article: Conversely, YouTube has also allowed government to more easily engage with citizens, the White House's official YouTube channel being the seventh top news organization producer on YouTube in 2012 and in 2013 a healthcare exchange commissioned Obama impersonator Iman Crosson's YouTube music video spoof to encourage young Americans to enroll in the Affordable Care Act (Obamacare)-compliant health insurance. In February 2014, U.S. President Obama held a meeting at the White House with leading YouTube content creators to not only promote awareness of Obamacare but more generally to develop ways for government to better connect with the "YouTube Generation". Whereas YouTube's inherent ability to allow presidents to directly connect with average citizens was noted, the YouTube content creators' new media savvy was perceived necessary to better cope with the website's distracting content and fickle audience.

Now answer this question: In 2013 who did the healthcare exchange commission to impersonate Obama and post it to youtube?

Output: Iman Crosson


Article: West's breakthrough came a year later on October 23, 2002, when, while driving home from a California recording studio after working late, he fell asleep at the wheel and was involved in a near-fatal car crash. The crash left him with a shattered jaw, which had to be wired shut in reconstructive surgery. The accident inspired West; two weeks after being admitted to the hospital, he recorded a song at the Record Plant Studios with his jaw still wired shut. The composition, "Through The Wire", expressed West's experience after the accident, and helped lay the foundation for his debut album, as according to West "all the better artists have expressed what they were going through". West added that "the album was my medicine", as working on the record distracted him from the pain. "Through The Wire" was first available on West's Get Well Soon... mixtape, released December 2002. At the same time, West announced that he was working on an album called The College Dropout, whose overall theme was to "make your own decisions. Don't let society tell you, 'This is what you have to do.'"

Here is a question about this article: In the early 20th century, many Europeans (particularly Spaniards and Italians but also thousands from Central Europe) immigrated to the city. In 1908, 30% of the city's population of 300,000 was foreign-born. In that decade the city expanded quickly: new neighbourhoods were created and many separate settlements were annexed to the city, among which were the Villa del Cerro, Pocitos, the Prado and Villa Colón. The Rodó Park and the Estadio Gran Parque Central were also established, which served as poles of urban development.
What is the answer to this question: In 1908 what percent of the city's population was foreign-born?
****
So... 30%


Article: An early advantage of AC is that the power-wasting resistors used in DC locomotives for speed control were not needed in an AC locomotive: multiple taps on the transformer can supply a range of voltages. Separate low-voltage transformer windings supply lighting and the motors driving auxiliary machinery. More recently, the development of very high power semiconductors has caused the classic "universal" AC/DC motor to be largely replaced with the three-phase induction motor fed by a variable frequency drive, a special inverter that varies both frequency and voltage to control motor speed. These drives can run equally well on DC or AC of any frequency, and many modern electric locomotives are designed to handle different supply voltages and frequencies to simplify cross-border operation.

Question: How can different range of voltages be supplied for AC locomotives?
Ans:
multiple taps on the transformer
