READ THE FOLLOWING POEM AND THEN ANSWER THE QUESTIONS THAT FOLLOW .
The light of the whole being,
The illuminator of my very self,
In your presence darkness exists no longer,
You make me feel bright and shining all over,
Oh! My moon.
My moon is still not yet fully full,
My moon is three-quarter full,
Still becoming what it will be,
But the brightness of my moon surpasses all other moons,
Oh! My moon.
My moon is uncomparable,
My moon has possession of the natural beauty,
The sight of my moon makes hearts stop a beat or melts hearts’
The smile of my moon makes the whole of my being hot and boiling,
Oh! My moon.
My moon when will you become a full moon?
I have waited long enough and my patience is fading away,
I may end up devouring my moon before it is fully ripe,
My moon my moon without you then I am not;
Oh! My moon
From when I wake I think only of you my moon,
At noon you are still dwelling in my mind,
In the evening I die just to see you,
And in the dark night I am restless and sleep never comes,
Oh! My moon.

Read the following excerpt and answer the questions that follow.
A DOLL’S HOUSE
Nora: But it was absolutely necessary that he should not know! My goodness cant you
Understand that? It was necessary he should have no idea what a dangerous condition he
Was in. It was to me that the doctors came and said that his life was in danger, and that the
only thing to save him was to live in the south. Do you suppose I didn’t try, first of all, to get
what I wanted as if it were for myself? I told him how much I should love to travel abroad
like other young wives; I tried tears and entreaties with him; I told him that he ought to
remember the condition I was in, and that he ought to be kind and indulgent to me ; I even
hinted that he might raise a loan. That nearly made him angry , Christine. He said I was
thoughtless, and that it was his duty as my husband not to indulge me in my whims and
caprices- as I believe he called them. Verywell, I thought you must be saved-and that was
how I came to devise a way out of difficulty-
Mrs. Linde: And did your husband never get to know from your father that the money had come
from him?
Nora:No, never. Papa died just at that time. I had meant to let him into the secret and beg him
never to reveal it. But he was so ill then –alas, there was never was any need to tell him.
Mrs. Linde : Good heavens, no! How could you think so? A man who has such strong opinion about
these things! And besides how painful and humiliating it would be for Torvald, with his
manly independence, to know that he owed me anything! It would upset our mutual
relations altogether; our beautiful happy home would no longer be what it is now
Mrs. LInde: Do you mean never to tell about it?
Nora:(meditatively and with a half-smile) Yes –someday perhaps, after many years, when I am no
longer as nice-looking as I am now. Don’t laugh at me! I mean, of course, when Torvald is no
longer as devoted to me as he is now; when my dancing and dressing –up and reciting have
paled on him; then it may be a good thing to have something in reserve-(breaking off)What
nonsense! That time will never come. Now what do you think of my greatest secret, Christine?
Do you still think I am of no use? I can tell you , too, that this affair has caused me a lot of
worry. It has been by no means easy for me to meet my engagements punctually. I may tell you
that there is something that is called in business, quarterly interest and another thing called
payment in installments and it is always so dreadfully difficult to manage them. I have not been
able to put a side much from housekeeping money for Torvald must have a good table. I could not
let my children be shabbily dressed; I have felt obliged to use up all he gave me for them, the sweet little darlings.
