Basic sanitation techniques can have a profound effect on the transmission of diarrheal disease. The implementation of hand washing using soap and water, for example, has been experimentally shown to reduce the incidence of disease by approximately 4248%. Hand washing in developing countries, however, is compromised by poverty as acknowledged by the CDC: "Handwashing is integral to disease prevention in all parts of the world; however, access to soap and water is limited in a number of less developed countries. This lack of access is one of many challenges to proper hygiene in less developed countries." Solutions to this barrier require the implementation of educational programs that encourage sanitary behaviours.
How much does hand washing reduce the chances of disease?
approximately 4248%

Input: Greeks
Greek surnames were widely in use by the 9th century supplanting the ancient tradition of using the father's name, however Greek surnames are most commonly patronymics. Commonly, Greek male surnames end in -s, which is the common ending for Greek masculine proper nouns in the nominative case. Exceptionally, some end in -ou, indicating the genitive case of this proper noun for patronymic reasons. Although surnames in mainland Greece are static today, dynamic and changing patronymic usage survives in middle names where the genitive of father's first name is commonly the middle name (this usage having been passed on to the Russians). In Cyprus, by contrast, surnames follow the ancient tradition of being given according to the father's name. Finally, in addition to Greek-derived surnames many have Latin, Turkish and Italian origin.

What does it mean to have the letters OU added to the ending of a males last name ?
Output: some end in -ou, indicating the genitive case of this proper noun for patronymic reasons.

Input: Article: In 2010 and 2011, state and federal funds were awarded to Connecticut (and Massachusetts) to construct the Hartford Line, with a southern terminus at New Haven's Union Station and a northern terminus at Springfield's Union Station. According to the White House, "This corridor [currently] has one train per day connecting communities in Connecticut and Massachusetts to the Northeast Corridor and Vermont. The vision for this corridor is to restore the alignment to its original route via the Knowledge Corridor in western Massachusetts, improving trip time and increasing the population base that can be served." Set for construction in 2013, the "Knowledge Corridor high speed intercity passenger rail" project will cost approximately $1 billion, and the ultimate northern terminus for the project is reported to be Montreal in Canada. Train speeds between will reportedly exceed 110 miles per hour (180 km/h) and increase both cities' rail traffic exponentially.

Now answer this question: What location provided the northern terminus for the Hartford Line?

Output: Springfield's Union Station

Article: The signatures of the parties' representatives follow at the very end. When the text of a treaty is later reprinted, such as in a collection of treaties currently in effect, an editor will often append the dates on which the respective parties ratified the treaty and on which it came into effect for each party.

Question: Even if signed and ratified on the same date, the treaty might have done what on different dates?
Ans: came into effect

Here is a question about this article: An influential school of phonology in the interwar period was the Prague school. One of its leading members was Prince Nikolai Trubetzkoy, whose Grundzuge der Phonologie (Principles of Phonology), published posthumously in 1939, is among the most important works in the field from this period. Directly influenced by Baudouin de Courtenay, Trubetzkoy is considered the founder of morphophonology, although this concept had also been recognized by de Courtenay. Trubetzkoy also developed the concept of the archiphoneme. Another important figure in the Prague school was Roman Jakobson, who was one of the most prominent linguists of the 20th century.
What is the answer to this question: What school was Trubetzkoy a member of?
****
So... the Prague school.

Article: Animal intestines contain a large population of gut flora. In humans, the four dominant phyla are Firmicutes, Bacteroidetes, Actinobacteria, and Proteobacteria. They are essential to digestion and are also affected by food that is consumed. Bacteria in the gut perform many important functions for humans, including breaking down and aiding in the absorption of otherwise indigestible food; stimulating cell growth; repressing the growth of harmful bacteria, training the immune system to respond only to pathogens; producing vitamin B12; and defending against some infectious diseases.

Question: Where could one find a large population of gut flora?
Ans:
Animal intestines
