Input: Read this: There are typically 40 million bacterial cells in a gram of soil and a million bacterial cells in a millilitre of fresh water. There are approximately 51030 bacteria on Earth, forming a biomass which exceeds that of all plants and animals. Bacteria are vital in recycling nutrients, with many of the stages in nutrient cycles dependent on these organisms, such as the fixation of nitrogen from the atmosphere and putrefaction. In the biological communities surrounding hydrothermal vents and cold seeps, bacteria provide the nutrients needed to sustain life by converting dissolved compounds, such as hydrogen sulphide and methane, to energy. On 17 March 2013, researchers reported data that suggested bacterial life forms thrive in the Mariana Trench, which with a depth of up to 11 kilometres is the deepest part of the Earth's oceans. Other researchers reported related studies that microbes thrive inside rocks up to 580 metres below the sea floor under 2.6 kilometres of ocean off the coast of the northwestern United States. According to one of the researchers, "You can find microbes everywhere they're extremely adaptable to conditions, and survive wherever they are."
Question: How many bacteria cells can be in a milliltre of fresh water?

Output: million bacterial cells

QUES: The Alma-Ata Protocol also addressed other issues, including UN membership. Notably, Russia was authorized to assume the Soviet Union's UN membership, including its permanent seat on the Security Council. The Soviet Ambassador to the UN delivered a letter signed by Russian President Yeltsin to the UN Secretary-General dated December 24, 1991, informing him that by virtue of the Alma-Ata Protocol, Russia was the successor state to the USSR. After being circulated among the other UN member states, with no objection raised, the statement was declared accepted on the last day of the year, December 31, 1991.

Which country took over the Soviet Union's UN membership?
What is the answer?
ANS: Russia

QUES: During the Middle Ages, Paris was a center of Jewish learning with famous Talmudic scholars, such as Yechiel of Paris who took part in the Disputation of Paris between Christian and Jewish intellectuals. The Parisian Jewish community was victim of persecution, alternating expulsions and returns, until France became the first country in Europe to emancipate its Jewish population during the French Revolution. Although 75% of the Jewish population in France survived the Holocaust during World War II, half the city's Jewish population perished in Nazi concentration camps, while some others fled abroad. A large migration of North Africa Sephardic Jews settled Paris in the 1960s, and represent most of the Paris Jewish community today. There are currently 83 synagogues in the city; The Marais-quarter Agoudas Hakehilos Synagogue, built in 1913 by architect Hector Guimard, is a Paris landmark.
When was the Marais-quarter Agoudas Hakehilos Synagogue built?

ANS: 1913

Arguing against the absolutist position, Leibniz offers a number of thought experiments with the purpose of showing that there is contradiction in assuming the existence of facts such as absolute location and velocity. These arguments trade heavily on two principles central to his philosophy: the principle of sufficient reason and the identity of indiscernibles. The principle of sufficient reason holds that for every fact, there is a reason that is sufficient to explain what and why it is the way it is and not otherwise. The identity of indiscernibles states that if there is no way of telling two entities apart, then they are one and the same thing.
If it is possible to answer this question, answer it for me (else, reply "unanswerable"): What states that two things are not necessarily the same just because no difference can be identified?
Ah, so.. unanswerable

Question: The change in political structure led to the inevitable development of the peasant class or smerdy. The smerdy were free un-landed people that found work by labouring for wages on the manors which began to develop around 1031 as the verv' began to dominate socio-political structure. The smerdy were initially given equality in the Kievian law code, they were theoretically equal to the prince, so they enjoyed as much freedom as can be expected of manual labourers. However, in the 13th century they began to slowly lose their rights and became less equal in the eyes of the law.
Try to answer this question if possible: Who began to slowly gain their rights and become more equal in the eyes of the law?
Answer: unanswerable

QUES: DC systems (especially third-rail systems) are limited to relatively low voltages and this can limit the size and speed of trains and cannot use low-level platform and also limit the amount of air-conditioning that the trains can provide. This may be a factor favouring overhead wires and high-voltage AC, even for urban usage. In practice, the top speed of trains on third-rail systems is limited to 100 mph (160 km/h) because above that speed reliable contact between the shoe and the rail cannot be maintained.
Why DC system can effect the speed of trains?

ANS:
low voltages
