QUES: Gorbachev's inability to alleviate any of Armenia's problems created disillusionment among the Armenians and fed a growing hunger for independence. In May 1990, the New Armenian Army (NAA) was established, serving as a defence force separate from the Soviet Red Army. Clashes soon broke out between the NAA and Soviet Internal Security Forces (MVD) troops based in Yerevan when Armenians decided to commemorate the establishment of the 1918 First Republic of Armenia. The violence resulted in the deaths of five Armenians killed in a shootout with the MVD at the railway station. Witnesses there claimed that the MVD used excessive force and that they had instigated the fighting.
What does NAA stand for?

ANS: New Armenian Army

QUES: The important legacy of this period included substantial advances in factual knowledge, especially in anatomy, zoology, botany, mineralogy, geography, mathematics and astronomy; an awareness of the importance of certain scientific problems, especially those related to the problem of change and its causes; and a recognition of the methodological importance of applying mathematics to natural phenomena and of undertaking empirical research. In the Hellenistic age scholars frequently employed the principles developed in earlier Greek thought: the application of mathematics and deliberate empirical research, in their scientific investigations. Thus, clear unbroken lines of influence lead from ancient Greek and Hellenistic philosophers, to medieval Muslim philosophers and scientists, to the European Renaissance and Enlightenment, to the secular sciences of the modern day. Neither reason nor inquiry began with the Ancient Greeks, but the Socratic method did, along with the idea of Forms, great advances in geometry, logic, and the natural sciences. According to Benjamin Farrington, former Professor of Classics at Swansea University:
Who employed logic, geometry, and natural sciences?

ANS: the Ancient Greeks

QUES: The climate of the Cretaceous is less certain and more widely disputed. Higher levels of carbon dioxide in the atmosphere are thought to have caused the world temperature gradient from north to south to become almost flat: temperatures were about the same across the planet. Average temperatures were also higher than today by about 10C. In fact, by the middle Cretaceous, equatorial ocean waters (perhaps as warm as 20 C in the deep ocean) may have been too warm for sea life,[dubious discuss][citation needed] and land areas near the equator may have been deserts despite their proximity to water. The circulation of oxygen to the deep ocean may also have been disrupted.[dubious discuss] For this reason, large volumes of organic matter that was unable to decompose accumulated, eventually being deposited as "black shale".
What atmospheric gas caused temperatures levels to be 10 degrees higher than today?

ANS: carbon dioxide

QUES: In Czech, nouns and adjectives are declined into one of seven grammatical cases. Nouns are inflected to indicate their use in a sentence. A nominativeaccusative language, Czech marks subject nouns with nominative case and object nouns with accusative case. The genitive case marks possessive nouns and some types of movement. The remaining cases (instrumental, locative, vocative and dative) indicate semantic relationships, such as secondary objects, movement or position (dative case) and accompaniment (instrumental case). An adjective's case agrees with that of the noun it describes. When Czech children learn their language's declension patterns, the cases are referred to by number:
When are nouns in Czech inflected?

ANS:
to indicate their use in a sentence
