PART B — (5 × 16 = 80 marks)
11. Read the following passage and answer the questions that follow it.
When the first white men arrived in Samoa, they found blind men, who could
see well enough to describe things in detail just by holding their hands over
objects. In France just after the First World War, Jules Romain tested
hundreds of blind people and found a few who could tell the difference between
light and dark. He narrowed their photosensitivity down to areas on the nose
or in the fingertips. In Italy the neurologist Cesare Lombroso discovered a
blind girl who could ‘see’ with the tip of her nose and the lobe of her left ear.
When a bright light was shone unexpectedly on her, she winced. In 1956 a
blind schoolboy in Scotland was taught to differentiate between coloured lights
and learned to pick out bright objects several feet away. In 1960 a medical
board examined a girl in Virginia and found that, even with thick bandages
over her eyes, she was able to distinguish different colours and read short
sections of large print. The phenomenon is obviously not new, but it has
reached new peaks of sensitivity in a young woman from a mountain village in
the Urals. 
Rosa Kuleshova can see with her fingers. She is not blind, but because she
grew up in a family of blind people, she learned to read Braille to help them
and then went onto teach herself to do other things with her hands. In 1962
her physician took her to Moscow, where she was examined by the Soviet
Academy of Science, and emerged a celebrity, certified as genuine. The
neurologist Shaefer made an intensive study with her and found that, securely
blindfolded with only her hands stuck through a screen, she could differentiate
among three primary colours. To test the possibility that the cards reflected
heat differently, he heated some and cooled others without affecting her
response to them, He also found that she could read newsprint and sheet music
under glass, so texture was giving her no clues. Tested by the psychologist
Novomeisky, she was able to identify the colour and shape of patches of light
projected on her palm or on to a screen. In rigidly controlled tests, with a
blindfold and a screen and a piece of card around her neck so wide that she
could not see round it, Rosa read the small print in a newspaper with her
elbow. And, in the most convincing demonstration of all, she repeated these
things with someone standing behind her pressing hard on her eyeballs.
Nobody can cheat under this pressure ; it is even difficult to see clearly for
minutes after it is released.
(a) Complete the following statements choosing from one of the given
alternatives. (4 × 1 = 4)
(i) The first white men to visit Samoa found men who
(1) were not entirely blind
(2) described things by touching them
(3) could see with their hands
(4) could see when they held hands
(ii) What is the main idea of the first paragraph?
(1) Very few people have the sensitivity of the blind
(2) Blind people can manage to see things, but only vaguely
(3) The eyes are not the only way of seeing
(4) It is possible to localise photosensitive areas of the body.
(iii) Why did Shaefer put the paper under glass?
(1) To make things as difficult as possible
(2) To stop the reflection of hear
(3) To prevent Rosa from feeling the print
(4) To stop her from cheating.


(iv) What was the most difficult test of her ability?
(1) To read through glass, blindfolded
(2) To identify the colour and shape of light on a screen while
securely blindfolded
(3) To carry out tasks with someone pressing on her eyeballs
(4) To work from behind a screen, blindfolded and with a card
round her neck.
(b) State whether the following statements are true or false. (8 × 1 = 8)
(i) The men in Samoa were not quite blind.
(ii) Jules Romain found a lot of blind people who could see with their
noses and ears.
(iii) The Italian girl enjoyed it when the light was shone on her ear.
(iv) A girl called Virginia could read newsprint even when she was
blindfolded.
(v) Rosa Kuleshova lives on a mountain peak.
(vi) Her family taught her everything about seeing with her fingers.
(vii) Shaefer found that temperature did not affect her ability to
differentiate between colours.
(viii) Her ability to read with her fingers did not depend on the feel of the
print.
(c) Choose the option that best represents the meaning of the word as used
in the passage. (4 × 1 = 4)
(i) distinguish
(1) differentiate
(2) discriminate
(3) revere
(4) standout
(ii) celebrity
(1) rejoice
(2) famous person

11. Read the following passage and answer the questions given at the end :
Learning is a process that every single human being undergoes. It is not just a
yearly or even monthly process, but a day-to-day one as well. We observe
people around us-how they speak and act. In learning about others, we learn
about ourselves in the bargain, and also how it is best to interact with other
people. We learn the true meaning of terms such as integrity, kindness,
sincerity, dedication, love, acceptance, appreciation, humility and
encouragement only from honest actions. Not just from words.
As students, we expect to learn these life lessons on campus — both within and
outside the classroom. Students play such an instrumental role in influencing
and educating fellow students. Sadly, it is very difficult to find students true to
their beliefs, firm in the stands they take and confident of their values. Many
take the easy way out, rather than being whom they truly are, which is not as
easy as it sounds. They slide into the easiest getaways camouflaged in the form
of a group of close friends.
Yet why do these students feel such a sense of loneliness? Why is it that even
though they appear to have things figured out, they are all still so alone? All
that I choose to boldly say is that if being different means that you stand alone,
then do not be afraid to be the only one brave enough to be the person everyone
is secretly wishing that he/she was.
The real dilemma in our educational system is that many students are afraid
to be who they really are. They have been taught by people around them that it
is not acceptable to laugh at things that other people do not think are funny,
that it is not proper for them to think differently from their parents and most
importantly, that it is not right to voice your own opinion.
Sooner or later, you will look upon yourself wondering how much you have
accomplished in life. However successful you may become, it is only the
satisfaction of embracing what really makes ‘‘you’’ and appreciating what you
really feel, that will make you genuinely happy. That is education at its best.


(a) Choose the correct answer : (5 × 1 = 5)
(i) What do we gain by learning about others?
(1) We learn about the environment
