Section A (Reading skill)
A.1. Read the following passage and answer the questions that follow. (5×1=5)
Mirrors have been used since ages. It is said that Archimedes used huge mirrors to focus the heat of the sun’s rays on the enemy ships to burn them.
The same principle is used in solar cookers where mirrors are used to reflect and focus the sun’s rays on to cooking containers. Astronomers use huge concave mirrors to focus starlight.
The mirrors used in telescopes are polished by giving a thin coat of silver or aluminum to the glass. With the telescopes, astronomers can see the heavenly bodies but even without the telescopes one can see the moon.
A full moon shining overhead is a beautiful sight, but it is also a puzzle because if the sun and the moon both give the same sunlight, then why is the moonlight more pleasant?
The reason is that the moon reflects very little sunlight, in fact, only seven percent of the light is receives.
The earth reflects about half of the radiation that it receives from the sun. Imagine how bright the earth will look from the moon?
One can even read a book on the moon in the earth light. However, you do not have to travel all the way to the moon to realise how strong the earthlight is.
Observe the crescent moon soon after the new moon. The bright crescent is illuminated by the sun.
The rest of the moon is illuminated by earthlight in other words, the light reflected by the earth is falling on the moon which is being reflected back to us and is strong enough to show the moon faintly as the crescent increases in size.
Fresh snow is the best reflector of sunlight in nature, the bright light reflected by it can dazzle and harm the eyes of mountaineers, therefore, they use dark glasses.
Choose the correct option.

A.2. Read the following poem and answer the questions. (5×1=5)
The World
Great, wide, beautiful, wonderful World,
With the wonderful water round you curled,
And the wonderful grass upon your breast—
World, you are beautifully drest.
The wonderful air is over me,
And the wonderful wind is shaking the tree,
It walks on the water, and whirls the mills,
3 / 6
And talks to itself on the tops of the hills.
You friendly Earth, how far do you go,
With the wheat-fields that nod and the rivers that flow,
With cities and gardens, and cliffs, and isles,
And people upon you for thousands of miles?
Ah! you are so great, and I am so small,
I tremble to think of you, World, at all;
And yet, when I said my prayers to-day,
A whisper inside me seemed to say,
You are more than the Earth, though you are such a dot:
You can love and think, and the Earth cannot!’
—W.B.Rands
