QUES: The Polish nobility differed in many respects from the nobility of other countries. The most important difference was that, while in most European countries the nobility lost power as the ruler strove for absolute monarchy, in Poland the reverse process occurred: the nobility actually gained power at the expense of the king, and the political system evolved into an oligarchy.

What did the political system eventually evolve into?
What is the answer?
ANS: oligarchy
QUES: The NES can be emulated on many other systems, most notably the PC. The first emulator was the Japanese-only Pasofami. It was soon followed by iNES, which was available in English and was cross-platform, in 1996. It was described as being the first NES emulation software that could be used by a non-expert. NESticle, a popular MS-DOS emulator, was released on April 3, 1997. There have since been many other emulators. The Virtual Console for the Wii, Nintendo 3DS and Wii U also offers emulation of many NES games.

What wasn't the first NES emulator?

QUES: 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 may be the result of developing effective ways to target new pathogens?
What is the answer?
