QUES: Law enforcement, however, constitutes only part of policing activity. Policing has included an array of activities in different situations, but the predominant ones are concerned with the preservation of order. In some societies, in the late 18th and early 19th centuries, these developed within the context of maintaining the class system and the protection of private property. Many police forces suffer from police corruption to a greater or lesser degree. The police force is usually a public sector service, meaning they are paid through taxes.
What kind of service aren't police?

ANS: unanswerable

QUES: Selenizza is a naturally occurring solid hydrocarbon bitumen found in the native asphalt deposit of Selenice, in Albania, the only European asphalt mine still in use. The rock asphalt is found in the form of veins, filling cracks in a more or less horizontal direction. The bitumen content varies from 83% to 92% (soluble in carbon disulphide), with a penetration value near to zero and a softening point (ring & ball) around 120 C. The insoluble matter, consisting mainly of silica ore, ranges from 8% to 17%.
What is it about the mine that is unusual?

ANS: still in use

QUES: Lie groups are of fundamental importance in modern physics: Noether's theorem links continuous symmetries to conserved quantities. Rotation, as well as translations in space and time are basic symmetries of the laws of mechanics. They can, for instance, be used to construct simple modelsimposing, say, axial symmetry on a situation will typically lead to significant simplification in the equations one needs to solve to provide a physical description.v["] Another example are the Lorentz transformations, which relate measurements of time and velocity of two observers in motion relative to each other. They can be deduced in a purely group-theoretical way, by expressing the transformations as a rotational symmetry of Minkowski space. The latter servesin the absence of significant gravitationas a model of space time in special relativity. The full symmetry group of Minkowski space, i.e. including translations, is known as the Poincare group. By the above, it plays a pivotal role in special relativity and, by implication, for quantum field theories. Symmetries that vary with location are central to the modern description of physical interactions with the help of gauge theory.
What term describes the basic symmetries of the laws of mechanics?

ANS: Rotation

QUES: The economy relies heavily on investment and support from Armenians abroad. Before independence, Armenia's economy was largely industry-based chemicals, electronics, machinery, processed food, synthetic rubber, and textile and highly dependent on outside resources. The republic had developed a modern industrial sector, supplying machine tools, textiles, and other manufactured goods to sister republics in exchange for raw materials and energy. Recently, the Intel Corporation agreed to open a research center in Armenia, in addition to other technology companies, signalling the growth of the technology industry in Armenia.
The Arnmenian economy depends primarily on what?

ANS:
investment and support from Armenians abroad
