Question: How much can fixing water contamination improve child mortality rates overall?, Context: Given that water contamination is a major means of transmitting diarrheal disease, efforts to provide clean water supply and improved sanitation have the potential to dramatically cut the rate of disease incidence. In fact, it has been proposed that we might expect an 88% reduction in child mortality resulting from diarrheal disease as a result of improved water sanitation and hygiene. Similarly, a meta-analysis of numerous studies on improving water supply and sanitation shows a 22–27% reduction in disease incidence, and a 21–30% reduction in mortality rate associated with diarrheal disease.

Answer: 88%


Question: what machine is mentioned first?, Context: Eventually, when it was more common for electric recordings to be played back electrically in the 1930s and 1940s, the overall tone was much like listening to a radio of the era. Magnetic pickups became more common and were better designed as time went on, making it possible to improve the damping of spurious resonances. Crystal pickups were also introduced as lower cost alternatives. The dynamic or moving coil microphone was introduced around 1930 and the velocity or ribbon microphone in 1932. Both of these high quality microphones became widespread in motion picture, radio, recording, and public address applications.

Answer: radio


Question: What else besides standards can be different depending on the school?, Context: Vinaya is the specific moral code for monks and nuns. It includes the Patimokkha, a set of 227 rules for monks in the Theravadin recension. The precise content of the vinayapitaka (scriptures on Vinaya) differs slightly according to different schools, and different schools or subschools set different standards for the degree of adherence to Vinaya. Novice-monks use the ten precepts, which are the basic precepts for monastics.

Answer:
scriptures on Vinaya
