NEST paper

Read the following passage carefully and answer questions 1.1 to 1.3.
Darwin had given the study of natural animal behaviour a scientific turn. He had seen the
central idea of ethology, that is animal behavioural routines are as important an aspect of the
animal’s adaptation to its environment as its anatomical structure or its physiological processes.
Routines are elaborate, integrated chains of behaviour directed to the achievement of certain
ends adaptive to the breeding success of a species.
As an example, consider the behavioural routine of gaping (wide opening of mouth) for food
amongst young birds. The capacities to recognise the right stimulus are not always inherited.
The young of many species of birds do not recognize conspecifics (birds of their own kind), if
they have not been introduced to them at a definite period of their development.
The young of Godwits hatch at an advanced stage of development and soon after hatching
can recognize the adult bird. The young birds immediately display appropriate behaviour in
the presence of adults, say gaping for food. They flee from human beings without any special
prompting or learning. For these birds and similar species, the capacity to recognize the object
of a behavioural routine, as well as the capacity to perform the routine, must be innate or
inherited.
On the other hand, the Greylag Geese do not have a prolonged period of hatching. They
vividly display another pattern of development. When young geese are reared wholly by human
beings it is towards humans that the young geese direct their behavioural routines. They seem
to acquire as a prime object of interest whatever creature happens to be present at the right
moment in their development. The first recorded observation of this phenomenon (now called
‘imprinting’) is due to Oskar Heinroth.
1.1 The word ‘conspecifics’ refers to
(A) Birds with a specific period of development.
(B) Birds displaying appropriate behaviour in the presence of adults.
(C) Birds of the same species.
(D) Bird species not needing any special prompting or learning

1.2 The pattern of development in Greylag Geese demonstrates that
(A) The hatching at an advanced stage is critical for imprinting.
(B) The capacity to recognise an adult of its own species is necessarily inherited.
(C) Rearing by humans does not alter the object of the behavioural routine.
(D) Geese reared by humans cannot be taught to respond to its own species.
1.3 Which of the following was an insight of Darwin?
(A) Behavioural animal routines need to be regarded as the animal’s environ-
mental adaptation.
(B) Behavioural animal routines are more significant than the anatomical structure in
the animal’s environmental adaptation.
(C) Behavioural animal routines are not related to environmental adaptation.
(D) Behavioural animal routines are always instinctive in their origin.
Read the following passage carefully and answer questions 1.4 to 1.6.
Cryptography is the practice and study of techniques for secure communication. Appli-
cations of cryptography include coded military messages, ATM cards and computer pass-
words. In cryptography, “encryption” is the process of converting ordinary messages (or
plaintext) into unintelligible text (or ciphertext). “Decryption” is the reverse, i.e. con-
verting the ciphertext back to plaintext. The method to encode and decode a message is
called a “cipher”. The cipher is controlled by a “key”. The key can be in the form of a
string of either characters or numbers and is the additional input necessary for encoding
or decoding the message.
In modern cryptography, symmetric-key cryptography refers to encryption methods in
which both the sender and the receiver share the same key. Symmetric key ciphers are
implemented as either block ciphers or stream ciphers. In a stream cipher, every character
of the plaintext is encoded by a single rule. A block cipher encrypts plaintext input
in blocks of fixed length of characters. Thus, adjacent characters may get encoded by
different rules. A major disadvantage of symmetric ciphers is that each distinct pair of
communicating parties must share a unique, different key. Thus, very large number of keys
are required in a big network of communicating parties. In public-key or asymmetric key
cryptography, two different but mathematically related keys are generated secretly, by an
intended recipient of the information. The public key, used for encryption may be freely
distributed by this recipient, while its paired private key, used for decryption, must remain
secret with him/her. Thus, in a public key encryption, senders of information will be able
to encrypt the information, but only the recipient will be able to decrypt the same.
1.4 In the public key cryptography, number of keys required for secure communication between n
parties will be,
(A) (n − 1)2
(B) 2n
(C)
n(n + 1)
2
(D)n(n − 1)
2

1.5 In a particular cipher, each character of the message is conveyed to the other party as a string
of numbers indicating a page number of a previously agreed book, a line number on that page
and the position of a character in that line. Choose the correct statement.
(A) The book in this example acts as a public key.
(B) The string of numbers in this example is a symmetric key.
(C) The text from the book is plaintext.
(D) This is an example of a symmetric key stream cipher.
1.6 In a particular cipher, 1st, 5th, 9th, ..., character in the text is replaced by the 4th letter of the
alphabet after that character and 4th, 8th, 12th, ..., character is replaced the 3rd letter of the
alphabet prior to that character. This is an example of,
(A) Symmetric key stream cipher.
(B) Symmetric key block cipher.
(C) Public key cipher.
(D) Information not sufficient.
