Read the excerpt below and then answer the questions that follow.
Krogstad: Are you aware that is a dangerous confession?
Nora: In what way? You shall have your money soon.
Krogstad: Let me ask you a question: Why did you not send the paper to your father?
Nora: It was impossible: papa was so ill. If I had asked him for his signature, I should have had to tell him what the money was to be used for: and when he was so ill himself, I couldn’t tell him that my husband’s life was in danger – it was impossible.
Krogstad: It would have been better for you if you had given up your trip abroad.
Nora: No, that was impossible. That trip was to save my husband’s life. I couldn’t give that up.
Krogstad: But did it never occur to you that you were committing a fraud on me?
Nora: I couldn’t take that into account: I didn’t trouble myself about you at all. I couldn’t bear you, because you put so many heartless difficulties in my way, although you knew what a dangerous condition my husband was in.
Krogstad : Mrs. Helmer, you evidently do not realise clearly what it is that you have been guilty of. But I can assure you that my one false step, which lost me all my reputation, was nothing more or nothing worse than what you have done.
Nora: You? Do you ask me to believe that you were brace enough to run a risk to save your wife’s life?
Krogstad: Foolish or not, it is the law by which you will be judged, if I produce this paper in court.
Nora: I don’t believe it. Is a daughter not to be allowed to spare her dying father anxiety and care? Is a wife not to be allowed to save her husband’s life? I dont know much about law: but I am certain that there must be laws permitting such things as that. Have you no knowledge of such laws – you who are a lawyer? You must be very poor Mr Krogstad.
Krogstad: Maybe. But matters of business – such business as you and I have had together – do you think I don’t understand that? Very well. Do as you please. But let me tell you this – if I lose my position a second time, you shall lose yours with me. (He bows and goes out through the hall) Nora (appears buried in thought for a short time, then tosses her head) Nonsense! Trying to frighten me like that! – I am not so silly as he thinks. (begins to busy herself putting the children’s things in order) And yet-? No it’s impossible! I did it for love’s sake.

Read the following passage and answer the questions that follow.
In the end I was duly discharged (from hospital) and sent back relieved but not cured. A very elaborate belt kept death at arm’s length. My congregation was deeply sympathetic, but started making representations for my transfer. Shortly afterwards the final blow was delivered. The circumstances in which I was forced to retire from the work for which I had sacrificed my youth and strength and hope were so confused and sad that a bitter taste will forever remain. I had toiled for over half a century only to end like this. Somehow I feel my third courtship had something to do with it, for I drew bitter opposition from some new relations of the lady. The campaign of mudslinging grew to ugly proportions and became an organized campaign to throw me out. Charges were tramped up. I was declared feeble, aged and unable to visit outstations, and probably I was secretly called immoral. These charges were duly handed to the superintendent minister.
Meanwhile at Mankessim angry mobs made the place untenable. I was in the end transferred – nowhere. That was the end. My retirement was skillfully managed by the chairman and superintendent minister, and I went quietly into obscurity with no lauvels and no respect, no last-minute farewell or godspeeds; no visible means of support save that which my own sons were hopefully expected to give. For catechists are the scum of the earth and command no respect and expect none. They are entitled to no gratuities or pension and when they are strong enough to outlive their usefulness….. “God will provide” I had worked half a century to bring salvation to other people. It would probably be appropriate to say, “Physician heal theyself.” Sometimes I think we, the workers in the Lord’s vineyard, have the greatest need of salvation ‘in the obscurity of retirement I can now have time to look back on my life and into my soul and try to assess where I failed and try to effect my own salvation.’ God indeed never leaves those who believe in Him really desolate. I have my wife with me now. My sons are all securely settled in life and work to support my old age. At the throne of God, I hope the Almighty will not deal too harshly with his servant, but in His infinite mercy will forgive my sins and accept even me.
(From: Joseph W. Abruquah, The Catechist, London – 1965)
