SECTION – A (READING – 15 MARKS)
1. Read the passage carefully and answer the questions that follow :
(8)
FATHER’S LAUGHTER
1.
When my father laughs, it is not only our home that reverberates but the
adjacent houses feel the ripples as well. He loves to laugh- only now, at a ripe
old age. In our younger days we hardly remember seeing or hearing him
laugh. He may have laughed in the company of his friends, but not at home.
My father, a professor of English, had ‘rigid, cold eyes’. His eyes never
flickered, penetrating deep into the person in front, if he happened to be the
target, enough to upset him from his seat. And they were cold not from an
absence of warmth, but like steel that had been tempered. Of course, it was
not for us to question why his eyes were cold or why he rarely laughed at home.
2.
Ours was to accept his authority in order to live. Every morning, we would try to
gauge father’s mood from the movement of his eyes or the few words he spoke.
If his voice didn’t have a rough edge, we would breathe and move around a bit
freely. On the other hand, when his throat produced grunts and rumbles, we
knew we had it for the day. The most difficult situation was when he was silent.
Unable to read him, we would be on the horns of a dilemma: Was it fine to go
for a football match? Or, would that invite a fine of two slaps, if not three
penalty kicks?
3.
My father’s moods were like Chennai’s climate - hot, hotter, hottest. Yet, like
millions of Madrasis who have not only survived their city’s climate but have
also grown to love it, we came to love our father the way he was.
(14)
4.
He kept us on a tight leash with his stern countenance, fearing that we would go
astray if given any liberties. Discipline was his motto, perhaps inherited from his
own English professors. For that, I am grateful to him.
5.
At the end of the day, he exudes a quiet smile of satisfaction at having reared a
breed of worthy citizens, if not exactly highly ‘valuable’ ones. Freed now from the
burden of bringing up children, my father has dispensed with his rigid, cold
façade. And he laughs a lot. He has to unload all those cans of laughter in him
that had their lids screwed on for so long. So it’s not strange that my children
refuse to believe that their grandfather and laughter were ever strangers.

2. Read the poem given below and answer the questions that follow :
From Cocoon Forth a Butterfly
FROM cocoon forth a butterfly
As lady from her door
Emerged—a summer afternoon—
Repairing everywhere,
Without design, that I could trace
Except to stray abroad
On miscellaneous enterprise
The clovers understood.
Her pretty parasol was seen
Contracting in a field
Where men made hay, then struggling hard
With an opposing cloud,
Where parties, phantom as herself,
To Nowhere seemed to go
(15)
(7)
In purposeless circumference,
As ’t were a tropic show.
And notwithstanding bee that worked,
And flower that zealous blew,
This audience of idleness
Disdained them, from the sky,
Till sundown crept, a steady tide,
And men that made the hay,
And afternoon, and butterfly,
Extinguished in its sea.
