Read the poem below and answer the questions that follow.
AN ELEGY
When he was here
We planned each tomorrow
With him in mind
For we saw no parting
Looming in the horizon
When he was here,
We joke and laughed together
And no fleeting shadow of a ghost
Ever crossed our paths
Day by day we lived
On this side of the mist
And there was never a sign
That his hours were running fast
When he was gone,
Through glazed eyes we searched
Beyond the mist and shadows
For we couldn’t believe he was nowhere
We couldn’t believe he was dead
(Laban Erapu)

Read the extract below from DOLL’S HOUSE and answer all the questions that follow.
Nora: Should? He did sign them.
Krogstad: I had left the date blank; that is to say, your father should himself have inserted the date on which he signed the paper. Do you remember that?
Nora: Yes, I think I remember—
Krogstad: Then I gave you the bond to send by post to your father. Is that not so?
Nora: Yes.
Krogstad: And you naturally did so at once, because five or six days afterwards you brought me the bond with your father's signature. And then I gave you the money.
Nora: Well, haven't I been paying it off regularly?
Krogstad: Fairly so, yes. But to come back to the matter in hand that must have been a very trying time for you, Mrs.
Nora: It was, indeed.
Krogstad: Your father was very ill, wasn't he?
Nora: He was very near his end.
Krogstad: And died soon afterwards?
Nora: Yes:
Krogstad: Tell me, Mrs Helmer, can you remember what day your father died? the month, I mean.
Nora: Papa died on the 29th of September. by any chance on what day of
Krostand: That is correct; I have ascertained it for myself. And, as that is so, there is discrepancy (taking a paper from his pocket) which I cannot account for.
Nora: What discrepancy? I don't know—
Krogstand: The discrepancy consists, Mrs. Helmer, in fact that your father signed this bond three days after his death.
Nora: What do you mean? I don't understand —
Krogstand: Your father died on the 29th of September. But, look here; your father has dated his signature the 2nd of October. It is a discrepancy, isn't it? (NORA is silent) Can you explain it to me?
(NORA is silent) It is a remarkable thing, too, that the words '2nd of October,' as well as the year, are not written in your father’s handwriting but in one that I think I know. Well, of course it can be explained; your father may have forgotten to date his signature, and someone else may have dated it haphazard before they knew of his death. There is no harm in that. It all depends on the signature of the name; and that is genuine. I suppose, Mrs. Helmer? It was your father himself who signed his name here?
Questions.
a) What is it that Nora claims to have signed? Explain.
b) What does this excerpt reveal about Krogstad's character?
c) Explain key theme brought out in the excerpt?
d) Why did Nora forge her father's signature?
e) What is the meaning of the following words as used in the excerpt?
I. Ascertained
II. Discrepancy
III. Genuine
f) Papa died on the 29th of September (Add a question tag.)
