9 Write a summary of the given passage : 5
Educational planning should aim at meeting the educational needs of the entire
population of all age groups. While the haditional structure of education as a three
layer hierarchy from the primary stage to the university represents the core, we should
not overlook the periphery, which is equally important under modem conditions.
Workers need to rewind or rcnew their enthusiasm, or strike out in a new direction, or
improve their skills as much as any university professor. The retired and the aged have
their needs as well. Fducational planning, in other words, should take care of the needs
of everyone.
10. Translate the following passage into Hindi : I
One of the greatest delusions of modem times is the prcvailing belief that we are more
civilized than our ancestors. At no other period in the history of mankind has the word
'civilization' been so often misused or misunderstood as in this age. It is not in the
abundance of material goods alone that civilization lies. Neither does it consist in the
advance of scientific knowledge however amazing it may be. The inventions and
discoveries of science have undoubtedly brought unheard of blessings and comforts to
us. But this is not civilization. The essential quality of civilization lies in the spirit of
man, in his attitude to himself, to his fellow men and to like as a whole.
