Read the following excerpt and answer the questions that follow.
A DOLL’S HOUSE
Nora: But it was absolutely necessary that he should not know! My goodness cant you
Understand that? It was necessary he should have no idea what a dangerous condition he
Was in. It was to me that the doctors came and said that his life was in danger, and that the
only thing to save him was to live in the south. Do you suppose I didn’t try, first of all, to get
what I wanted as if it were for myself? I told him how much I should love to travel abroad
like other young wives; I tried tears and entreaties with him; I told him that he ought to
remember the condition I was in, and that he ought to be kind and indulgent to me ; I even
hinted that he might raise a loan. That nearly made him angry , Christine. He said I was
thoughtless, and that it was his duty as my husband not to indulge me in my whims and
caprices- as I believe he called them. Verywell, I thought you must be saved-and that was
how I came to devise a way out of difficulty-
Mrs. Linde: And did your husband never get to know from your father that the money had come
from him?
Nora:No, never. Papa died just at that time. I had meant to let him into the secret and beg him
never to reveal it. But he was so ill then –alas, there was never was any need to tell him.
Mrs. Linde : Good heavens, no! How could you think so? A man who has such strong opinion about
these things! And besides how painful and humiliating it would be for Torvald, with his
manly independence, to know that he owed me anything! It would upset our mutual
relations altogether; our beautiful happy home would no longer be what it is now
Mrs. LInde: Do you mean never to tell about it?
Nora:(meditatively and with a half-smile) Yes –someday perhaps, after many years, when I am no
longer as nice-looking as I am now. Don’t laugh at me! I mean, of course, when Torvald is no
longer as devoted to me as he is now; when my dancing and dressing –up and reciting have
paled on him; then it may be a good thing to have something in reserve-(breaking off)What
nonsense! That time will never come. Now what do you think of my greatest secret, Christine?
Do you still think I am of no use? I can tell you , too, that this affair has caused me a lot of
worry. It has been by no means easy for me to meet my engagements punctually. I may tell you
that there is something that is called in business, quarterly interest and another thing called
payment in installments and it is always so dreadfully difficult to manage them. I have not been
able to put a side much from housekeeping money for Torvald must have a good table. I could not
let my children be shabbily dressed; I have felt obliged to use up all he gave me for them, the sweet little darlings.

- Read the following passage and then answer the questions that follow. (Solved)
Read the following passage and then answer the questions that follow.
Government housing policy should deliberately promote affordable housing to avoid mushrooming of slums and create decent accommodation for lower and medium income households.
Housing still remains unaffordable for the majority of Kenyans because of an insensitive housing policy and declining incomes.
The government’s lip-service regarding affordable housing means that a majority of Kenyans especially those residing in Nairobi continue to wallow in housing poverty having only slums as their accommodation.
As a matter of facts, very few estates in Nairobi can escape the UN definition of a slum. This is because they lack the essential facilities that are deemed to provide decent accommodation.
It is not uncommon to find a household made up of six adults staying in a one-roomed house. This invades personal space, reduces creativity and makes life just mere survival. Residents are normally pre-occupied with survival instead of building the nation.
Several factors combine to create this housing crunch. These include salaries and wages that have not kept pace with housing costs.
Many employers do not factor the cost of housing in their compensation packages. Pushed by tough economic times and the profit maximization motive, many employers are happy to give a consolidated pay. It is up to the employees to allocate their income to get decent accommodation.
Also most jobs are low paying. Statistics shows that a majority of Kenyans earn less than 10,000 per month.
This small sum is meant to meet accommodation needs, beside other equally important family obligation. With poor wages, most people cannot afford decent accommodation.
Since housing for lower and middle-income groups does not offer good returns, investment in this sector is diminishing by the day. The return here is way below what developers get in up market housing.
With the economy now registering 4.3 percent growth there are high hopes that there will be a huge demand for housing.
According to international practice, housing is considered “affordable” if it costs no more than 30 per cent of the monthly household income for rent and utilities. If your household Income is Ksh 10,000 per month, you should pay more than Ksh 3000 monthly for your rent and utilities.
That is why affordable housing is an indispensable proposition in Kenya today. Affordable housing is a concept that can serve Kenya well and offer a solution to the social –economic development of lower and middle – income households.
Affordable housing should serve young families, a stable place to get back to after a hard day building the nation.
It. Is a cost-effective living situation for persons with special needs.
Affordable housing developments normally meet local building standards and designs requirements.
Professional on-site resident management includes stringent tenant selection and quick responses to maintenance requirements.
In other developed economies. Private developers, mostly non-profit co-operative societies, develop affordable housing using a combination of rental income, private funding and government subsidies.
Over the past decade, it has become increasingly clear that partnerships among local government, non-profit housing developers, community leaders and private financial institutions can create attractive and affordable housing that not only serve residents, but is an asset to the broader community,
The benefits that accrue from affordable housing are immense. It provides housing for the local workforce, especially lower wage earners, besides revitalizing distressed,
Affordable housing is also used to direct economic benefits to the local community, e.g. increased jobs, reduced traffic and better air quality.
It is upon the government to come up with policies which promote partnerships with the private sector to ensure affordable housing for all Kenyans

a) Why should the government housing policy promote affordable housing?
b) Show why the housing has remained out of reach to many Kenyans.
