In 2009 NASA said that they had found a lot of water on the moon. The water is not liquid but is in the form of hydrates and hydroxides. Liquid water cannot exist on the Moon because photodissociation quickly breaks down the molecules. However, from the image NASA received, there is a history of water existence.
During the Cold War, the United States Army thought about making a military post on the Moon, able to attack targets on Earth. They also considered conducting a nuclear weapon test on the Moon. The United States Air Force had similar plans. However, both plans were brushed-off as NASA moved from a military to a civilian-based agency.
Even though the Soviet Union left remains on the Moon, and the United States left a few flags, no country has control over the Moon. The U.S. and Soviet Union both signed the Outer Space Treaty, which calls the Moon and all of outer space the "province of all mankind". This treaty also banned all use of the military of the Moon, including nuclear weapons tests and military bases.

Captivity (animal)
Animals who live under human control or care are in captivity. Captivity can be used as a term meaning the keeping of either domesticated animals (livestock, pets) or wild animals. This may include for example farms, private homes and zoos. Sometimes humans take care of critically endangered animals and therefore these animals are in captivity.
Choctaw
The Choctaw are a Native American people originally from the southeastern United States.
Native Americans in the United States
Native Americans in the United States (also known as Indians) are the indigenous peoples from the areas of North America now part of the continental United States, including parts of Alaska. The Cherokee were the first Native Americans to be recognized as US citizens. In the 19th century white colonists called the Cherokee one of the Five Civilized Tribes. The others were Chicksaw, Choctaw, Creek and Seminole.
There are about 310 Indian reservations in the US. Most Native Americans do not live on a reservation anymore.
Native Americans are affected by some problems more than White Americans. For example Native Americans are six times more likely to suffer from alcoholism than average. About 24% live in extreme poverty. Native American and Native Alaskan women are more likely to be targets of sexual violence than other women.

Ob River
The Ob is a river in Siberia. Together with the Lena and the Jenissei, it is one of the most important rivers of Siberia. Depending upon how its length is measured, it can be between 3.650 km and 6.210 km long. Some important cities on the banks of the river include Novosibirsk(Russia's third largest city), Barnaul, Kolpashevo, Nizhnevartovsk, Surgut, Khanty-Mansiysk, Beryozovo, Labytnangi, and Salekhard. The Irtysh is the Ob river's main tributary. Other tributaries include the Omsk, Parabel, Chaya, Tobol and Ishim.
Deductive reasoning
Deduction is one of the two main types of reasoning. The other is induction. In deduction, we apply a general rule to a particular case.
Deductive arguments are attempts to show that a conclusion must follow from a set of premises or hypotheses. A deductive argument is valid if the conclusion follows necessarily from the premises.
Aristotle, the first person we know who wrote down laws of deduction, gives this example of deduction:
The first two statements are called "premises". The last statement is called the "conclusion". The conclusion is taken from the premises.
Deductive reasoning is often called "top-down logic", whereas inductive reasoning is called "bottom-up reasoning".
Inductive reasoning
Induction is one of the main forms of logical reasoning. The other is deduction. In induction, we find a general rule by using a large number of particular cases. For example, watching water in many different situations, we can conclude that water always flows downhill.
Induction is not the method of science, but it can be the starting-point for science. Everyone can see that the sun, moon and stars appear to move across the sky. Early civilisations thought this meant they revolved around the Earth, because that is what they always seem to do. We now know this is quite wrong, but discovering the real explanation was the start of modern science (see Copernicus, Galileo and heliocentrism). What they did was to work out an alternative theory or hypothesis, which eventually was shown to be a much better explanation of all the observations. That is real science, but the observations of the heavens, which started with the Babylonians, showed the regularity which needed to be explained. What science did was to prove the obvious explanation was not the right one.
