Tea is an evergreen shrub. The word ‘evergreen” means that old leaves remain on the shrub, while new once come out. There is no drying or falling of leaves as in the case of other trees and plants. In a wild state the
plant grow to an enormous height ranging from twenty five to thirty feet. But under cultivation it is not allowed to grow higher than four or five feet. The growth upward is checked by pruning while this operation serves to
increase the growth of leaves below. The leaves of plant are one to two inches in length. Their colour is green and shape is oval. The tea plant grows best of all, in places where there is plenty of rain as well as sunshine. The
cultivation was perhaps first made in china and hence, it is the real home of the plant. Now, however, it is abundantly grown in Japan, Sri Lanka, Assam and Darjeeling in India. Tea does not grow in cold countries. Hence, there are no tea plantation in Europe, though it is favorite beverage there

Direction for  Question  No. 1 - 5 : Read  the passage    and  answer   the questions   based  on it.

I have  three  visions  for India.  In 3000 'years  of our  history  people -frorn all. over  the  world  have  come  and  invaded  us,  captured   our  lands,   conquered'  our minds.   From   Alexander   onwards   the   Greeks,   the'  Turks,    the   . Moguls,  the Portuguese,   the  British,  the  French,  the  Dutch,  all of them  came  and  looted us,took over what  was ours.  Yet we have not done this  to any other  nation.  We have' not  conquered   anyo~e .. We have  not  grabbed  their  land,  their  culture   and  their history  and  tried to enforce our way of life on them.  Why?  Because  we respet  the freedom  of others.  That  is why my FIRST VISION is that  of FREEDOM. I believe that   India   got  its .first  vision  of  this   in  1857,  when  we  started   the  Wat  of Independence.   It is this  freedom that  we must  protect  and  nurture   and  build  on.If we are not free,  no one will respect  us.                                                                          .
We have  10 per cent growth in most areas.  Our poverty levels are falling. Our  achievements   are being globally recognised  today.  Yet we lack  the  self confidence to  see  ourselves  as  a developed  nation,   self-reliant   and  self assured.   Isn't. this incorrect?    MY SECOND VISION for India  is DEVELOPMENT. For  fifty years  we have  been  a. developing nation.  It is time we see ourselves  as a developed  nation. We are among  top five nations  in' the world in terms  of GDP. I have THIRD VISION India  must  stand  up to the world. Because  I believe that  unless   India  stands   up to the world, no one will-respect  us.  Only strength  respects   strength:   We must  be strong  not only as a military power but  also as an economic  power.

1'.    'In 3000 year~ manycountries    invaded India. What damage  did they do to us?

In towns and cities of north and west India, kite flying is a craze. People fly their kites mostly from the roofs of their houses. At some places kites are flown from open grounds. Being a fun sports all times, kites are flown throughout the year. However there are some special occasions, on which every enthusiast involves himself in Patang Baazi. These occasions include Makar Sankranti, Basant Panchami, Raksha Bandhan, and Independence Day.
Basant Panchami is one of the biggest festivals of North India. It heralds both the approach of the harvest and the end of winter. This spring festival is celebrated by flying kites, mainly of yellow colour, which represents the ripening mustard in the fields. From the morning onwards, the roofs of almost every house become full of young and old keeping their kites afloat. By early afternoon, the sky becomes peppered with kites of different colours and sizes. The fun of Basant Panchami does not preclude the intense competition that is a unique north Indian phenomenon- cutting each other’s kite lines. Each time a kite’s lifeline is severed, a cheer, “ Bo- kata: (loosely translated as “akite cut off”), is sent up by the victor.
