Problem: Please answer a question about the following article about Windows 8:
The term "Immersive app" had been used internally by Microsoft developers to refer to the apps prior to the first official presentation of Windows 8, after which they were referred to as "Metro-style apps" in reference to the Metro design language. The term was phased out in August 2012; a Microsoft spokesperson denied rumors that the change was related to a potential trademark issue, and stated that "Metro" was only a codename that would be replaced prior to Windows 8's release. Following these reports, the terms "Modern UI-style apps", "Windows 8-style apps" and "Windows Store apps" began to be used by various Microsoft documents and material to refer to the new apps. In an interview on September 12, 2012, Soma Somasegar (vice president of Microsoft's development software division) confirmed that "Windows Store apps" would be the official term for the apps. An MSDN page explaining the Metro design language uses the term "Modern design" to refer to the language as a whole.
When did Windows Store apps become the real term for the apps?
A: September 12, 2012

Problem: Traditionally a carnival feast was the last opportunity to eat well before the time of food shortage at the end of the winter during which one was limited to the minimum necessary. On what nowadays is called vastenavond (the days before fasting) all the remaining winter stores of lard, butter and meat which were left would be eaten, for it would soon start to rot and decay. The selected livestock had in fact already been slaughtered in November and the meat would be no longer preservable. All the food that had survived the winter had to be eaten to assure that everyone was fed enough to survive until the coming spring would provide new food sources.
Why were the winter stores of lard and meat eaten before fasting?
The answer is the following: it would soon start to rot and decay

After the Soviet Union launched the world's first artificial satellite in 1957, Eisenhower authorized the establishment of NASA, which led to the space race. During the Suez Crisis of 1956, Eisenhower condemned the Israeli, British and French invasion of Egypt, and forced them to withdraw. He also condemned the Soviet invasion during the Hungarian Revolution of 1956 but took no action. In 1958, Eisenhower sent 15,000 U.S. troops to Lebanon to prevent the pro-Western government from falling to a Nasser-inspired revolution. Near the end of his term, his efforts to set up a summit meeting with the Soviets collapsed because of the U-2 incident. In his January 17, 1961 farewell address to the nation, Eisenhower expressed his concerns about the dangers of massive military spending, particularly deficit spending and government contracts to private military manufacturers, and coined the term "militaryindustrial complex".
What organization did Eisenhower support after the Soviets launched the first artificial satellite?
NASA

Problem: Please answer a question about the following article about Diarrhea:
Immunization against the pathogens that cause diarrheal disease is a viable prevention strategy, however it does require targeting certain pathogens for vaccination. In the case of Rotavirus, which was responsible for around 6% of diarrheal episodes and 20% of diarrheal disease deaths in the children of developing countries, use of a Rotavirus vaccine in trials in 1985 yielded a slight (2-3%) decrease in total diarrheal disease incidence, while reducing overall mortality by 6-10%. Similarly, a Cholera vaccine showed a strong reduction in morbidity and mortality, though the overall impact of vaccination was minimal as Cholera is not one of the major causative pathogens of diarrheal disease. Since this time, more effective vaccines have been developed that have the potential to save many thousands of lives in developing nations, while reducing the overall cost of treatment, and the costs to society.
What year was the Rotovirus vaccine used?
A:
1985
