Read the following passage carefully and answer questions from 31 to 35 :
If India has to develop her internal strengths, the nation has to focus on the technological
imperatives, keeping in mind three dynamic dimensions : the people, the overall economy and the
strategic interests. These technological imperatives also take into account a ëfourthí dimension,
time, an offshoot of modern day dynamism in business, trade, and technology that leads to
continually shifting targets. We believe that technological strengths are especially crucial in dealing
with this fourth dimension underlying continuous change in the aspirations of the people, the
economy in the global context and the strategic interests. The progress of technology lies at the
heart of human history. Technological strengths are the key to creating more productive employment
in an increasingly competitive market place and to continually upgrade human skills. Without a
pervasive use of technologies, we cannot achieve overall development of our people in the years
to come. The direct linkages of technology to the nation's strategic strengths are becoming more
and more clear, especially since 1990s. India's own strength in a number of core areas still puts
it in a position of reasonable strength in geo-political context. Any nation aspiring to become a
developed one needs to have strengths in various strategic technologies and also the ability to
continually upgrade them through its own creative strengths. For people-oriented actions as well,
whether for the creation of large scale productive employment or for ensuring nutritional and
health security for people, or for better living conditions, technology is the only vital input. The
absence of greater technological impetus could lead to lower productivity and wastage of precious
natural resources. Activities with low productivity or low value addition, in the final analysis hurt
the poorest most. The technological imperatives to lift our people to a new life, and to a life they
are entitled to is important. India, aspiring to become a major economic power in terms of trade
and increase in GDP, cannot succeed on the strength of turnkey projects designed and built
abroad or only through large-scale imports of plant machinery, equipment and know how. Even
while being alive to the short-term realities, medium and long-term strategies to develop core
technological strengths within our industry are vital for envisioning a developed India.
