Nora: It’s a shame to say that. I do really save all I can.
Helmer:(laughing)That’s very true, - all you can. But you can’t save anything!
Nora: (smiling quietly and happily)You haven’t any idea how many expenses we skylarks and squirrels have, Torvald.
Helmer: You are an odd little soul. Very like your father. You always find some new way of wheedling money out of me, and as soon as you have got it, it seems to melt in your hands. You never know where it has gone. Still, one must take you as you are. It is in the blood: for indeed it is true that you can inherit these things, Nora.
Nora: Ah, I wish I had inherited many of papa’s qualities.
Helmer:And I would not wish you to be anything but just what you are, my little skylark. But do you know, it strikes me that you are looking-rather—what shall I say- rather uneasy today?
Nora: Do I?
Helmer: You do, really. Look straight at me.
Nora : ( looks at him) well?
Helmer: (wagging his finger at her) Hasn’t Miss Sweet Tooth been breaking rules in town today?
Nora: No; what makes you think that?
Helmer: Hasn’t she paid a visit to the confectioner’s?
Nora: No, I assure you, Torvald-
Helmer: Not been nibbling sweets?
Nora: No, certainly not.
Helmer: Not even take a bite at a macaroon or two?
Nora: (going to the table on the right) I shouldn’t think of going against your wishes.
Helmer: No, I am sure of that: besides, you gave me your word- (Going up to her) Keep your little Christmas secrets to yourself, my darling. They will be revealed tonight when the Christmas tree is lit, no doubt.
Nora: Did you remember to invite Doctor Rank?
Helmer: No. But there is no need; as a matter of course, he will come to dinner with us. However, I will ask him when he comes this morning. I have ordered some good wine. Nora, you can’t think how I am looking forward to this evening.
Nora: So am I! And how the children will enjoy themselves, Torvald!

- Read the following passage and then answer the questions that follow. (Solved)
Read the following passage and then answer the questions that follow.
The question is at least as old as Socrates: If we know what the right thing to do is, why do we not do it? It is an especially acute question when applied to global warming. The science showing that carbon dioxide emissions are already changing the planet’s climate, and are likely to have severe effects (melting ice caps, sea-level rise, and species extinction), is compelling and now barely disputed. Almost 90% of Europeans say they recognize climate change as a major issue, and 75% identify fossil fuel emissions as a major cause.
And yet, as was widely discussed at a conference of environmentalists, geologists and writers in May 2006 in Ankelohe, Germany, public understanding has not translated into even the simplest of public actions. Less than 1% of Britons, for example, have switched their home electricity to renewable sources, even though it requires little more than a phone call to one’s existing provider. Proportions on the continent are slightly higher, but there is clearly no rush to go green or — shudder — stop driving cars.
Why such a disconnect between information and action? Part of the problem is that environmental advocates emit mixed messages. In mid-May 2006, Britain’s Guardian published a front-page story showing that five companies in Britain produce more CO2 pollution in a year than all the country’s motorists combined. That is a strong argument for targeting industries, but the average reader could hardly be blamed for thinking, “Why should I bother to cut down my driving?”
Similarly, not enough thought has been devoted to the best role for government. Climate change is too vast a problem for individuals to solve alone, and some big businesses have an incentive not to solve it. That leaves government to take the lead, which is tricky, because over-reliance on government can allow individuals to fob off their own responsibilities. What is worse, government power seems to tickle autocratic fantasies. In my experience, environmentalists spend far too much energy advocating hard-line government ‘solutions’ that do not stand a chance of being enacted. Sure, it might be good for the planet if governments banned the use of sports-utility vehicles or, for that matter, of all fossil fuels. Yet not only is it hard to sell outright prohibitions to voters, but the sad truth is that governments have a woeful record in even the mildest interventions. One of the most significant innovations in the last decade has been Europe’s carbon-emission trading scheme: some 12 000 companies, responsible for more than half of the EU’s emissions, have been assigned quotas. Companies with unused allowances can sell them; the higher the price, the greater the incentive for firms to cut their use of fossil fuels. The system seemed to work for about a year — but now it turns out that Europe’s governments allocated far too many credits, which will likely hinder the program’s effectiveness for years.
Perhaps the real reason that well-intentioned consumers do not change is that they do not see any benefit. Climate change may be a frightening, irreversible calamity, but its worst effects will not be felt next week or next year. The planet looks the same regardless of whether we use environmentally friendly technology or we do not care how much CO2 we emit. But sure as the sun rises and sets every day, if we do not cut down on carbon emissions, then we may not have a planet to hand over to the next generation.

Mrs. Linde: Listen to me Nora you are still very like a child in many things, and I am older than you in many ways and have a little more experience. Let me tell you this-you ought to make an end of it with Doctor Rank.
Nora : What ought I to make an end to?
Mrs. Linde: Of two things I think. Yesterday you talked some nonsense about a rich admirer who was to leave you money-
Nora Linde: Is Doctor Rank a man of means?
Mrs. Linde: And comes here every day?
Nora : Yes, I told you so.
Mrs. Linde: But how can this well-bred man be so tactless?
Nora : I don’t understand you at all.
Mrs. Linde:Don’t prevaricate, Nora.do you suppose I don’t guess who lent you the two
hundred and fifty pounds?
Nora :Are you out of your senses? How can you think of such a thing? A friend of ours,
who comes hereevery day! Do you realize what a horribly painful position that
would be?
Mrs. Linde: Then it really isn’t he?
Nora : No, certainly not. It would never have entered into my head for a moment.
Besides, he had no money to lend then; he came into his money afterwards.Mrs. Linde: Well I think that was lucky for you, my dear Nora.
Nora :No, it would never have come into my head to ask Doctor Rank. Although I am
quite sure if I had asked him-
Mrs. Linde: But of course you won’t.
Nora: Of course not. I have no reason to think it could possibly be necessary. But I am
quite sure that if I told Doctor Rank-
Mrs. Linde: Behind your husband’s back?
Nora : I must make an end of it with the other one, and that will be behind his back too, I
must make an end of it with him.
Mrs. Linde: Yes, that is what I told you yesterday, but-
Nora : ( walking up and down) a man can put a thing like that straight much easier
than a woman.
Mrs. Linde: One’s husband , yes.
Nora : Nonsense!( standing still) When you pay off a debt you get your bond back, don’t
you?
Mrs. Linde:Yes, as a matter of course.
Nora : And can tear it into a hundred thousand pieces and burn it up- the nasty dirty
paper.
Mrs. Linde:(looks hard at her, lays down her sewing and gets up slowly.) Nora you are

- Read the following passage and answer the questions that follow.(Solved)
Read the following passage and answer the questions that follow.
When in early 1970s ultrasound confronted me with the sight of the embryo in a womb, I simply lost my faith in abortion on demand. I did not hold onto my old convictions. The change was in its way a clean and surgical conversion. I am by nature one that works out the conflicting data, weighs the opposing argument with great care, decides and then acts upon it with no lingering backward glances.
By 1984 however, I had begun to ask myself more questions about abortion: What actually goes on in an abortion? I had done many but abortion is a blind procedure. The doctor does not see what he is doing. He puts an instrument into a uterus and he turns on a mortar and a suction machine goes on and something is vacuumed out; it ends up as little pile of meat in a gauze bag. I wanted to know what happened, so in 1984 I said to a friend of mine who was doing fifteen or maybe twenty abortions a day:‘ Look ,do me a favour,Jay .Next Saturday when you are doing all these abortions put an ultra sound on the mother and tape it on me.”
He did, and when he looked at the tapes with me in the editing studio, he was so affected that he never did another abortion. Although I had not performed an abortion in five years, I was shaken to the very roots of my soul by what I saw. The tapes were shockingly amazing. Some of the tapes weren’t of very good quality but I selected one that was of better quality than the others and began to show it at pro- life gatherings around the country.(I had my first contact with pro-life movement in 1981 when the then president of the National Right to Life Committee, Carolyn Gerster, had gotten in touch with me).
At the time, I was speaking at a pro-life meetings around the country in weekends, and the response to the tape was so intense and dramatic that finally I was approached by a man named Don Smith, who wanted to make my tape into a film. I agreed that it would be good idea. That is how The Silent Scream, which was to generate so many furore, came to be made. We showed it for the first time in Fort Lauderdale, Florida, on January3, 1985. The reaction was instantaneous. Everybody was up in arms because The Silent Scream represented an enormous threat to the abortion forces, and because it escalated the war (it is not really a debate- we don’t debate with each, we scream at one another). For the first time, we had the technology, and they had nothing.
The Silent Scream depicted a twelve- week- foetus being torn to pieces in the uterus by the combination of suction and crushing instrumentation by the abortionist. It was so powerful that pro choicers trotted out their heaviest hitters to denounce the tape. They very cleverly deflected the impact of the film into an academic cul- de- suc: a dispute regarding whether the foetus feels pain during an abortion. The impetus for the debate came from an on – the- record musing by the then President, Ronald Reagan, as to how much pain the foetus feels during an abortion.
