SECTION – A : Reading (15 marks)

1. Read the following passage carefully and answer the questions that follow :
Many of us believe that ‘small’ means ‘insignificant’. We believe that small actions
and choices do not have much impact on our lives. We think that it is only the big things, the
big actions and the big decisions that really count. But when you look at the lives of all great
people, you will see that they built their characters through small decisions, small choices
and small actions that they performed everyday. They transformed their lives through a step
by step or day by day approach. They nurtured and nourished their good habits, one step at a
time. It was their small day to day decisions that added up to make tremendous difference in
the long run. Indeed, in matters of personal growth and character building, there is no such
thing as overnight success.
Growth always occurs through a sequential series of stages. There is an organic process
to growth. When we look at children growing up, we can see this process at work: the child
first learns to crawl, then to stand and walk, and finally to run. The same is true in the natural
world. The soil must first be tilled, and then the seed must be sowed. Next, it must be nurtured
with enough water and sunlight, and only then will it grow, bear fruit and finally ripen, ready to
be eaten.
Gandhi understood this organic process and used this universal law of nature to his
benefit. Gandhi grew in small ways, in his day-to-day affairs. He did not wake up one day and
find himself to be the ‘Mahatma’. In fact, there was nothing much in his early life that showed
signs of greatness. But from his mid-twenties, he deliberately and consistently attempted to
change himself, reform himself and grow in some way everyday. Day-by-day, hour-by-hour,
he risked failure, experimented and learnt from his mistakes. In small and large situations
alike, he took up rather than avoided responsibility.
People have always marvelled at the effortless way in which Gandhi could accomplish
the most difficult tasks. He displayed a great deal of self-mastery and discipline which was
amazing.These things did not come easily to him.Years of practice and disciplined training
went into making his success possible. Very few saw his struggles, fears, doubts and anxieties,
or his inner efforts to overcome them. They saw the victory but not the struggle.

This is a common factor in the lives of great people. They exercise their freedom and
choices in small ways that have a great impact on their lives and their environment. Each of
their small decisions and actions add up to have a profound impact in the long run. By
understanding this principle, we can move forward with confidence, in the direction of our
dreams. Often when our ‘ideal goal’ looks far from us, we become easily discouraged,
disheartened and pessimistic. However, when we choose to grow in small ways, taking small
steps one at a time, it becomes easy to achieve the goal.

1.1. Based on your understanding of the passage, answer the following questions briefly : 2x2=4
(a) What is ‘organic process of growth’?
(b) Which part of Gandhi’s life is not seen by most people?

1.2. Select the appropriate answer from the given options : 2x1=2
(a) Which of the following statement is true in the context of the third paragraph?
(i) Gandhi became great overnight.
(ii) Gandhi showed signs of greatness in childhood itself.
(iii) Everyday, Gandhi made efforts to change himself in some small way.
(iv) Gandhi never made mistakes.

(b) Why do we become easily discouraged, disheartened and pessimistic?
(i) Because our ‘ideal goal’ looks too far from us.
(ii) Because things do not come easily to us.
(iii) Because we choose to grow in small ways.
(iv) Both (i) and (ii).

1.3. Find words in the passage which are similar in meaning to the following : 2x1=2
(a) intentionally or purposely
(b) of deep significance

2. Read the following passage and answer the questions that follow :
There is nothing more frustrating than when you sit down at your table to study with the
sincerest of intentions and instead of being able to finish the task at hand, you find your
thoughts wandering. However, there are certain techniques that you can use to enhance your
concentration. “Your concentration level depends on a number of factors,” says Samuel Ghosh,
a social counsellor. “In order to develop your concentration span, it is necessary to examine
various facets of your physical and internal environment,” he adds.
To begin with, one should attempt to create the physical environment that is conducive
to focused thought. Whether it is the radio, TV or your noisy neighbours, identify the factors
that make it difficult for you to focus. For instance, if you live in a very noisy neighbourhood,
you could try to plan your study hours in a nearby library. He disagrees with the notion that
people can concentrate or study in an environment with distractions like loud televisions,
blaring music, etc. If you are distracted when you are attempting to focus, your attention and
retention powers do not work at optimum levels,” cautions Ghosh. “Not more than two senses
should be activated at the same time,” he adds. What that means is that music that sets your
feet tapping is not the ideal accompaniment to your books. Also do not place your study table

or desk in front of a window. “While there is no cure for a mind that wants to wander, one
should try and provide as little stimulus as possible. Looking out of a window when you are
trying to concentrate will invariably send your mind on a tangent,” says Ghosh.
The second important thing, he says is to establish goals for oneself instead of setting
a general target and then trying to accomplish what you can in a haphazard fashion. It is very
important to decide what you have to finish in a given span of time. The human mind recognizes
fixed goals and targets and appreciates schedules more than random thoughts. Once your
thoughts and goals are in line, a focused system will follow.
Divide your schedules into study and recreation hours. When you study, choose the
mix of subjects that you enjoy and dislike. For instance, if you enjoy verbal skill tests more
than mathematical poblems, then finish maths first. Not only will you find yourself working
harder, you will have a sense of achievement when you wind up.
Try not to sit for more than 40 minutes at a stretch. Take a very short break and sit down
again. Short breaks build your concentration and refresh your mind. However, be careful not
to overdo the relaxation. It may have undesired effects.
Do not get disheartened. Concentration is merely a matter of disciplining the mind. It
comes with patience and practice and does not take very long to become a habit for life.
