SECTION – A : READING [20 Marks]
1. Read the passage given below and answer the questions that follow :
(12)
Your Amazing Brain
By: Douglas A. Richards
You carry around a three-pound mass of wrinkly material in your head that controls
every single thing you do. From enabling you to think, learn, create, and feel to
controlling every blink, breath, and heartbeat - this fantastic control center is your
brain. It is a structure so amazing that a famous scientist once called it "the most
complex thing we have yet discovered in our universe."
Your brain is faster and more powerful than a supercomputer.
Your kitten is on the kitchen counter. She's about to step onto a hot stove. You have
only seconds to act. Accessing the signals coming from your eyes, your brain quickly
calculates when, where, and at what speed you will need to dive to intercept her.
Then it orders your muscles to do so. Your timing is perfect and she's safe. No
computer can come close to your brain's awesome ability to download, process, and
react to the flood of information coming from your eyes, ears, and other sensory
organs.
Your brain generates enough electricity to power a light bulb.
Your brain contains about 100 billion microscopic cells called neurons - so many that
it would take you over 3,000 years to count them all. Whenever you dream, laugh,
think, see, or move, it’s because tiny chemical and electrical signals are racing
between these neurons along billions of tiny neuron highways. Believe it or not, the
activity in your brain never stops. Countless messages zip around inside it every
second like a supercharged pinball machine. Your neurons create and send more
messages than all the phones in the entire world.
Neurons send information to your brain at more than 150 miles per hour.
(3)
A bee lands on your bare foot. Sensory neurons in your skin relay this information to
your spinal cord and brain at a speed of more than 150 miles per hour. Your brain
then uses motor neurons to transmit the message back through your spinal cord to
your foot to shake the bee off quickly. Motor neurons can relay this information at
more than 200 miles per hour.
When you learn, you change the structure of your brain.
Riding a bike seems impossible at first. But soon you master it. How? As you practice,
your brain sends "bike riding" messages along certain pathways of neurons over and
over, forming new connections. In fact, the structure of your brain changes every
time you learn, as well as whenever you have a new thought or memory.
Exercise helps make you smarter.
It is well known that any exercise that makes your heart beat faster, like running or
playing basketball, is great for your body and can even help improve your mood. But
scientists have recently learned that for a period of time after you've exercised, your
body produces a chemical that makes your brain more receptive to learning. So if
you're stuck on a homework problem, go out and play a game of soccer, then try the
problem again. You just might discover that you're able to solve it.

(8)
Hearing
by David Bouchard
As you walk along the ocean
And peer out toward the water
And you see a log that’s floating—
Look again, it might be me.
Come right down into the harbour,
But be quick, I must keep moving.
I am one the orca’s hunting,
And he frequently swims here.
Like the orca, I send signals,
Only mine sound much like clicking.
They bounce back with a clear message:
“Is it time to flee or eat?”
It would serve me if you showed Them
How I dive into the ocean.
How the channels to my ears fill
And then serve me like a drum
That amplifies the slightest sound—
That’s how I hear in water.
(5)
There’s more that makes me special.
I can hear on land as well.
They have surely heard me talking
With my friends out on their shores.
Come and look across your harbour.
I’m here peeking. Can you see me?
Please be quick. I must keep moving.
Now you see me, now you don’t.
