elephants, and to share knowledge and
positive solutions for the better care and
management of captive and wild elephants.
30. (C) The chemical formula for Nitrolim talc is
[Mg2 (Si2O5)2 . Mg(OH)2]
32. (A) BCD is a binary coded notation in which
each of the decimal digits is expressed as a
8-bit binary numeral. For example in binary
coded decimal notation 12 is 0001 0010 as
opposite to 1100 in pure binary.
34. (C) India's first repository on tigers will be
set up by the Wildlife Institute of India (WII)
under its new Tiger Cell at Dehradun,
Uttarakhand. The cell will have a database
of tigers from over 50 reserves around the
country along with their DNA and stripes
samples to keep a track on their numbers. If
a tiger skin is recovered, the tiger cell will
help in locating the area from where it came
from. The purpose of the repository is to aid
conservation efforts by keeping an update on
tiger numbers as well as tracking poaching
incidents throughout the country. The tiger
cell will be funded by the National Tiger
Conservation Authority (NTCA), which is a
statutory body under the Ministry of
Environment. It will also give clearance to
development projects in areas with tiger
population.
36. (A) The book "What Lies Between Us" has
been authored by Nayomi Munaweera. It is

superimposed drainage. A superimposed
river does not adjust with the structure of
its place of origin. First of all the river valley
is built on upper part and then the river
develops and expands such structure in the
lower part.

45. (C) White cement does not contain iron,
hence it is white (as iron reacts with H2O of
atmosphere and forms FeS, which is black
in colour).
46. (C) Agriculture continues to play the primary
role in the country's development and is still
the mainstay to our large growing population
for its sustained food security.
47. (C) Madhya Pradesh is the only Diamond
