PASSAGE I (Question Nos. 191 to 195)
Consumer culture may be defined as an indomitable
passion for the purchase and possession of material goods
and services, usually in the high-cost bracket. It is perceived
as a symbol of affluence and aristocracy in the society.
Companies take advantage of this idiosyncrasy in people
and accordingly idolise their products to augment sales.
Two characteristic features distinguish a consumer
economy. First, it is defined by the spree of spending andbuying by the people. Second, consumer culture hinges
not so much on the purchasing power of money, as it does
on creating happiness and a sense of satisfaction obtained
through acquiring and owning personal property.
Consumer culture may be viewed both positively and
negatively. Proponents say that people are happier and
more productive when their wants are met. The contrary
perspective is that consumerism is wasteful and greedy;
that it encourages consumption for its own sake. However,
both sides agree that consumerism is a sign of freedom
and choice.
Nevertheless, during the last quarter of the last century,
as technological advancement leapfrogged, the traditionalroles of the supplier and consumer were changed beyond
recognition. Consumer sovereignty asserted itself; and
both the consumer and the supplier entered into a symbiotic
relationship in which their mutual loyalty was manifest.
They reached a definitive role as equal partners in the
business process.
Therefore, as at present, it is not the supplier who
dictates what a society shall buy and use, but rather the
free-thinking and self-directed consumer who decides what
he wants and will possess. This drives the economy into a
liberal, laissez faire, strong, and stable system; purchases
lead to more purchases and the wheels of production keep
churning all the time.Perhaps, one of the most liberating aspects of
consumer culture is the concept of creating a new self, a
different avatar, by transforming the person into a more
modern individual, and conferring on him a new identity.
The phenomenon of consumer culture is so completely
engrossedin the idea of modernity that the world is no
longer governed by custom, conformity, or tradition; but
by flux, fashion, fancy, and fanfare.
191. According to the given passage, what is consumer
culture?
(A) Consumer culture is the tendency of consumers
to purchase foreign-made goods.
(B) Consumer culture is the strong will to purchase
and possess costly goods and services.
(C) Consumer culture is a business term associated
with the behaviour of consumers.
(D) Consumer culture is related to identifying the
members of affluent society and selling them
costly products.
192. Which of the following is associated with the
consumer economy?
(A) Desire of the people to freely spend and purchase
goods
(B) Purchasing power of money
(C) Inflation and availability of goods and services
(D) Brand names
193. Find the incorrect statement on the basis of the given
passage.(A) When the wants of the people are met they
become happy and their productivity increases.
(B) Consumerism is associated with waste of money;
also it gives birth to greed.
(C) Consumerism is the reflection of choice and
freedom.
(D) There was no remarkable technological
development between the year 1975 and 2000.
194. Which of the following statements is not true about
changing consumer culture?
(A) At present, it is the consumer who decides the
nature of the products.
(B) The relation between the consumer and thesupplier is that of mutual benefit.
(C) The consumer culture is guided not by fashion
but by tradition.
(D) In consumer culture supplier and consumer play
the role as equal partners.
195. What is the meaning of the word engrossed as used
in the given passage?
(A) exalted (B) exasperated
(C) occupied (D) intensified
PASSAGE II (Question Nos. 196 to 200)
The Kathopanishad features a story found in the Rig
Veda to bring to light subtle aspects of the search for the
highest knowledge. Not all are capable of imbibing thisknowledge. Nor can inference or direct perception help in
this regard. It is to be gained only through the teaching of
those to whom these profound truths are revealed. In this
story, Yama and Nachiketa exemplify the qualifications and
eligibilities of the preceptor and the true seeker, pointed
out Sri N Veezhinathan in a discourse.
Nachiketa is the son of Vajasrava, a pious Brahmana,
who performs a sacrifice and gives away old cows as

presents to priests. Nachiketa is disturbed as he realises
that his father will be adversely affected by giving such
worthless gifts. He asks his father, To whom will you offer
me as a gift? The father initially ignores the question but
when the son persists, he replies impatiently that he would
offer him to Yama. Immediately, both father and son feel
sad about the implications of this utterance. But Nachiketa
decides to obey his father and goes to Yamas abode.
Finding that Yama is not there, he waits for three days.
When Yama returns, he is apologetic for this lapse in
hospitality and after due honours to the guest, wishes to
recompense the boy by offering him three boons.
Nachiketa asks for the welfare of his father as he desires
to return alive to the world as his first boon. He wishes that
his father is freed of anxiety, and that he should remain
calm in mind. This boon is granted.
For the second boon, Nachiketa wishes to know how
people can gain access to heaven since it is believed that
the dwellers in heaven are free of hunger, fear or old ageand they gain immortality. Yama describes in detail the fire
sacrifice and its procedure and grants an extra (fourth)
boon that this fire sacrifice will be known by the name
of Nachiketa.
For the third boon, Nachiketa pitches for the
knowledge of the self that transcendsimpermanent ends
and which is gained by eliminating natural ignorance.
196. Why did Yama offer three boons to Nachiketa?
(A) Because Nachiketa was a very young boy
obedient to his father.
(B) Because Nachiketa had requested him for boons.
(C) Because Yama wanted to compensate his lapse in
hospitality.
(D) Because Nachiketa was the son of a reverend
Brahmana.
197. What was the reason of Nachiketas disturbance?
(A) Vajasrava had cursed him to death.
(B) Vajastava was dishonest in presenting the gifts
to priests.
(C) Nachiketa was afraid of going to Yamas abode.
(D) Vajasrava had ignored his requests.
198. How can one gain the highest knowledge?
(A) By reading the Kathopanishad
(B) By studying all the four Vedas
(C) By listening to the sermons of Rishis and going
to temples
(D) None of the above
199. Which of the following is not true according to the
given passage?(A) Nachiketa was granted four boons by Yama.
(B) In the first boon, Nachiketa asked for the welfare
of his father.
(C) The second boon is related to fire sacrifice.
(D) Vajasrava did not like his obstinate son and
offered him to Yama.
