Question: Time is one of the seven fundamental physical quantities in both the International System of Units and International System of Quantities. Time is used to define other quantitiessuch as velocityso defining time in terms of such quantities would result in circularity of definition. An operational definition of time, wherein one says that observing a certain number of repetitions of one or another standard cyclical event (such as the passage of a free-swinging pendulum) constitutes one standard unit such as the second, is highly useful in the conduct of both advanced experiments and everyday affairs of life. The operational definition leaves aside the question whether there is something called time, apart from the counting activity just mentioned, that flows and that can be measured. Investigations of a single continuum called spacetime bring questions about space into questions about time, questions that have their roots in the works of early students of natural philosophy.

Answer: unanswerable
Question: The Archaic period in the Americas saw a changing environment featuring a warmer more arid climate and the disappearance of the last megafauna. The majority of population groups at this time were still highly mobile hunter-gatherers; but now individual groups started to focus on resources available to them locally, thus with the passage of time there is a pattern of increasing regional generalization like, the Southwest, Arctic, Poverty, Dalton and Plano traditions. This regional adaptations would become the norm, with reliance less on hunting and gathering, with a more mixed economy of small game, fish, seasonally wild vegetables and harvested plant foods.
Try to answer this question if possible: The minority of population groups at this time were what?
Answer: unanswerable
Question: The Nea Moni Monastery on Chios was established by Constantine Monomachos in 10431056. The exceptional mosaic decoration of the dome showing probably the nine orders of the angels was destroyed in 1822 but other panels survived (Theotokos with raised hands, four evangelists with seraphim, scenes from Christ's life and an interesting Anastasis where King Salomon bears resemblance to Constantine Monomachos). In comparison with Osios Loukas Nea Moni mosaics contain more figures, detail, landscape and setting.
Try to answer this question if possible: When was the Nea Moni Monastery established?
Answer: 10431056
Question: In 2006, due to ongoing violence, over 50,000 people in the country's northwest were at risk of starvation but this was averted due to assistance from the United Nations.[citation needed] On 8 January 2008, the UN Secretary-General Ban Ki-Moon declared that the Central African Republic was eligible to receive assistance from the Peacebuilding Fund. Three priority areas were identified: first, the reform of the security sector; second, the promotion of good governance and the rule of law; and third, the revitalization of communities affected by conflicts. On 12 June 2008, the Central African Republic requested assistance from the UN Peacebuilding Commission, which was set up in 2005 to help countries emerging from conflict avoid devolving back into war or chaos.
