- Read the excerpt below and then answer the questions that follow.
(Solved)
Read the excerpt below and then answer the questions that follow.
Nora. What right have you to question me, Mr.Krogstad?–You, one of my husband’s subordinates! But since you ask, you shall know. Yes, Mrs. Linde is to have an appointment. And it was I who pleaded her cause, Mr. Krogstad, let me tell you that.
Krogstad. I was right in what I thought, then.
Nora (walking up and down the stage). Sometimes one has a tiny little bit of influence, I should hope. Because one is a woman, it does not necessarily follow that–. When anyone is in a subordinate position, Mr. Krogstad, they should really be careful to avoid offending anyone who–who–
Krogstad. Who has influence?
Nora. Exactly.
Krogstad (changing his tone). Mrs. Helmer, you will be so good as to use your influence on my behalf.
Nora. What? What do you mean?
Krogstad. You will be so kind as to see that I am allowed to keep my subordinate position in the Bank.
Nora. What do you mean by that? Who proposes to take your post away from you?
Krogstad. Oh, there is no necessity to keep up the pretence of ignorance. I can quite understand that your friend is not very anxious to expose herself to the chance of rubbing shoulders with me; and I quite understand, too, whom I have to thank for being turned off.
Nora. But I assure you–
Krogstad. Very likely; but, to come to the point, the time has come when I should advise you to use your influence to prevent that.
Nora. But, Mr. Krogstad, I have no influence.
Krogstad. Haven’t you? I thought you said yourself just now–
Nora. Naturally I did not mean you to put that construction on it. I! What should make you think I have any influence of that kind with my husband?
Krogstad. Oh, I have known your husband from our student days. I don’t suppose he is any more unassailable than other husbands.
Nora. If you speak slightingly of my husband, I shall turn you out of the house.
Krogstad. You are bold, Mrs. Helmer.
Nora. I am not afraid of you any longer. As soon as the New Year comes, I shall in a very short time be free of the whole thing.
Krogstad (controlling himself ). Listen to me, Mrs.Helmer. If necessary, I am prepared to fight for my small post in the Bank as if I were fighting for my life.
Nora. So it seems.
Krogstad. It is not only for the sake of the money; indeed, that weighs least with me in the matter. There is another reason–well, I may as well tell you. My position is this. I daresay you know, like everybody else, that once, many years ago, I was guilty of an indiscretion
Nora. I think I have heard something of the kind.
Krogstad. The matter never came into court; but every way seemed to be closed to me after that. So I took to the business that you know of. I had to do something; and, honestly, I don’t think I’ve been one of the worst. But now I must cut myself free from all that. My sons are growing up; for their sake I must try and win back as much respect as I can in the town. This post in the Bank was like the first step up for me–and now your husband is going to kick me downstairs again into the mud.
Nora. But you must believe me, Mr. Krogstad; it is not in my power to help you at all.
Krogstad. Then it is because you haven’t the will; but I have means to compel you.
(a) Krogstad asks four questions just before this excerpt. Which are they?
(b) For what reasons has Krogstad visited Nora? Refer to what happens in the excerpt and in the rest of the play.
(c) “I was right in what I thought, then.” What do you think Krogstad thought?
(d) Describe two character traits of Nora as brought out in the excerpt.
(e) Rewrite the sentences according to the instructions given after each without changing their meanings.
i. If you speak slightingly of my husband, I shall turn you out of the house.Use: Unless…
ii. So it seems.
supply a question tag
(f) Highlight two themes evident in this excerpt.
(g) “Then it is because you haven’t the will; but I have means to compel you.” How does Krogstad plan to force Nora to talk to her husband?
(h) Write a word with the same meaning as each of the following words as used in the excerpt.
i. Necessity ………………………………………………………
ii. Pleaded ………………………………………………………………
iii. Influence ………………………………………………………………

- Read the passage below and then answer the questions that follow.(Solved)
Read the passage below and then answer the questions that follow.
A lot of students think that learning is only in class. If students use two extra steps, most students will not forget what they learned in class. To achieve effective learning, students needed to follow two extra steps in the three strategic learning processes.
The key to success is by following these three strategies. Review is essential to student success. Unless content is reviewed by students shortly after it is learned, it will soon be forgotten. To avoid forgetting what you learned, it is recommended to review daily.
It is also recommended to reduce large volumes of notes into point form and to paraphrase what you have learned. Other helpful tips include creating concept maps and diagrams; creating fact, concept or vocabulary cards and using visualization to better connect to what you learned. These are all important tools to helping students better understand and memorize lesson content.
The key to achieving academic success cannot be directly correlated to one specific area. Rather it requires students to be overall rounded in many different aspects. This includes attending class regularly to keep pace with the class. Falling behind in studies or homework can be detrimental to academic success and can induce stress onto students. Participating in class activities and discussions are also vital parts of learning and applying concepts learned. On the other hand, taking good, concise notes will always help in the long run when reviewing for tests
and exams. To sum it all up, strategic learning is the password for many academic achievements. Being exposed to knowledge is the first step in the journey, the fact that young scholars can learn and be a part of history is a phenomenal step in furthering their search to success. Reviewing notes, in the way the young individual wishes, by him/herself, or with a good friend, this will help him/her to understand what has been learned in a way s/he understands. Lastly practice is a great way to memorise what has been learned, when practice achieves its full potential, the individual won’t only be entitled for a good mark, but also a way to view, under and think of things. Those three attributes will help scholars become more successful, but it’s important to one as it is to the other, and each and every person should find the learning strategies effectual for him/herself, and in extremely exceptional occasions even invent or innovate new strategies.
