Explanation

(a)The concept of diminishing marginal utility holds that as additional unit of a commodity is consumed, it adds less and less to total utility and later adds nothing to total utility. Further consumption leads to negative values, then total utility diminishes as reflected in the total curve dropping downwards.

(b) A consumer's utility is maximized when the marginal utility per amount spent on a product is equal to the marginal utility per amount spent on any other product. It can be written mathematically asMux=Muy=Mz

Px Py Pz

Where MUx, Muy, Muz represent the marginal utilities of products x, y, .z

while Px, Py, Pz represent their prices respectively.

In the case of one commodity, a consumer will maximize his utility when the MU of that commodity equals the price of the commodity, e.g. MUx= Px

Explanation

In literature, a tragic character is one that experiences a downfall due to their own flaw or mistake. The downfall of this character arouses feelings of pity and fear (or terror) in the audience. This is a concept known as 'catharsis', a term used by Aristotle in his work 'Poetics', to describe the feelings of pity and fear that the audience feels for the tragic hero.

Explanation

The novel provides a graphic picture of a society that is rooted in custom and tradition and Pokuwaa is no exception. Her devotion to carrying out the sacrifices and purification rites marks her out as a devotee of tradition. However, there is loss of confidence and disenchantment when she discovers that in spite of this religious devotion through sacrifices to the gods, her ambition is far from being realized. When thunder strikes the baobab tree outside the village, the people of Brenhoma feel it is a bad omen and that the gods are angry and must be pacified. Pokuwaa seriously takes part in the purification rites, praying that the gods will make her fertile. She has performed several purification rites to the god Tano and has consulted several herbalists without success. To add to her disappointment, she realizes that there is little difference between the herbal medicines given to her by the Tano priest and the ones she has received from other herbalists - medicines which has failed to work. This accentuates her doubts about the efficacy of traditional medicine. Her doubts even extend to the belief in ancestral influences.

Her journey to the Ananse stream, though made in ignorance, reveals an attitude of mind that has given up the idea of strictly following the tradition of the society. When Pokuwaa is urged to return the hornbill which she has caught from an eagle, she goes just a few yards into the bush and throws the hornbill away.

The resolve by Pokuwaa to discontinue making sacrifices to the gods is an expression of dissatisfaction with the state of affairs. She destroys the pot she has hitherto used to prepare the herbal drugs and burns the talisman she has worn round her waist. After she has done all these, she experiences peace. Thus her becoming pregnant only after she has discontinued the sacrifice, is a vindication of her refusal to adhere slavishly to tradition and spells victory for her:

Dear Sister,

I was unhappy and disappointed after reading your last letter. Though I appreciate the confidence you have in me I disapprove of your plan to elope with Peter, your lover. I will be very frank and blunt with you because I still don't know what brought that kind of inglorious plan to your mind.

How do you think that you are going to be respected by your junior brothers and sisters if you carry out your plan? Nobody respects a lady who elopes with her lover against her parents' wishes. Don't you realize that you are laying down a bad example which should not be emulated? What befits you as the eldest daughter in the family is to wed a man of your choice with the approval of daddy and mummy. Moreover, if you elope with your lover now, how do you expect him to respect you? I am sure you are going to regret it later in life because those who have carried out what you are planning now ended up being dumped by their husbands.

Secondly, you are going to bring a stigma into the family. I want you to think seriously about your parents whom you want to disgrace and put to shame in our town. I advise you not to bring such ridicule to our parents. It is abominable and unheard i of in the annals of our town for a young beautiful girl like you to elope with a man whom her parents do not approve of.

Thirdly, the bible goes against your plan. As a christian, you are expected to be joined to a man of your choice whom your parents approve of. This means that if you carry out your plan, you will be committing a sin towards God. Therefore, you have to be careful and change your plan.

In order to obtain our parents' consent, I want you to go and see uncle Ade. As you know that daddy and mummy always listen to him, go and tell him that you are in love with Peter and that you are convinced that he loves you too. Then, solicit his assistance to talk to our parents so as to convince them that irrespective of the fact that Peter doesn't belong to our tribe, you can still marry him and have joy and peace.

I am sure that if you take this step, our parents will consent to your courtship and later marriage to Peter.

Yours sincerely,

Joke.
