QUES: Writings in Estonian became significant only in the 19th century with the spread of the ideas of the Age of Enlightenment, during the Estophile Enlightenment Period (17501840). Although Baltic Germans at large regarded the future of Estonians as being a fusion with themselves, the Estophile educated class admired the ancient culture of the Estonians and their era of freedom before the conquests by Danes and Germans in the 13th century.

When did the ancient Estonian era of freedom come to an end?
What is the answer?
ANS: 13th century
QUES: Since annelids are soft-bodied, their fossils are rare mostly jaws and the mineralized tubes that some of the species secreted. Although some late Ediacaran fossils may represent annelids, the oldest known fossil that is identified with confidence comes from about 518 million years ago in the early Cambrian period. Fossils of most modern mobile polychaete groups appeared by the end of the Carboniferous, about 299 million years ago. Palaeontologists disagree about whether some body fossils from the mid Ordovician, about 472 to 461 million years ago, are the remains of oligochaetes, and the earliest indisputable fossils of the group appear in the Tertiary period, which began 65 million years ago.

What fossil signs of annelids are found?
What is the answer?
ANS: jaws and the mineralized tubes that some of the species secreted
QUES: Between 7 September 1940 and 21 May 1941, 16 British cities suffered aerial raids with at least 100 long tons of high explosives. Over a period of 267 days, London was attacked 71 times, Birmingham, Liverpool and Plymouth eight times, Bristol six, Glasgow five, Southampton four, Portsmouth and Hull three and a minimum of one large raid on eight other cities. This was a result of a rapid escalation starting on 24 August 1940, when night bombers aiming for RAF airfields drifted off course and accidentally destroyed several London homes, killing civilians, combined with the UK Prime Minister Winston Churchill's retaliatory bombing of Berlin on the following night.[clarification needed]
