Question: The most common forms of uranium oxide are triuranium octoxide (U
3O
8) and UO
2. Both oxide forms are solids that have low solubility in water and are relatively stable over a wide range of environmental conditions. Triuranium octoxide is (depending on conditions) the most stable compound of uranium and is the form most commonly found in nature. Uranium dioxide is the form in which uranium is most commonly used as a nuclear reactor fuel. At ambient temperatures, UO
2 will gradually convert to U
3O
8. Because of their stability, uranium oxides are generally considered the preferred chemical form for storage or disposal.
Try to answer this question if possible: Along with UO2, what is the least commonest form of uranium oxide?
Answer: unanswerable
Question: At Buya in Eritrea, one of the oldest hominids representing a possible link between Homo erectus and an archaic Homo sapiens was found by Italian scientists. Dated to over 1 million years old, it is the oldest skeletal find of its kind and provides a link between hominids and the earliest anatomically modern humans. It is believed that the section of the Danakil Depression in Eritrea was also a major player in terms of human evolution, and may contain other traces of evolution from Homo erectus hominids to anatomically modern humans.
Try to answer this question if possible: How far back do scientists think archaic Homo sapiens transitioned to anatomically modern humans?
Answer: unanswerable
Question: Japan conscripted many soldiers from its colonies of Korea and Formosa (Taiwan). To a small extent, some Vichy French, Indian National Army, and Burmese National Army forces were active in the area of the Pacific War. Collaborationist units from Hong Kong (reformed ex-colonial police), Philippines, Dutch East Indies (the PETA) and Dutch Guinea, British Malaya and British Borneo, Inner Mongolia and former French Indochina (after the overthrow of Vichy French regime) as well as Timorese militia also assisted Japanese war efforts.
Try to answer this question if possible: What colonies did Japan conscript soldiers from?

Question: In Ancient Greece, green and blue were sometimes considered the same color, and the same word sometimes described the color of the sea and the color of trees. The philosopher Democritus described two different greens; cloron, or pale green, and prasinon, or leek green. Aristotle considered that green was located midway between black, symbolizing the earth, and white, symbolizing water. However, green was not counted among of the four classic colors of Greek painting; red, yellow, black and white, and is rarely found in Greek art.
