Read the narrative below and then answer the questions that follow.
Once upon a time, all animals in the jungle were of the same plain colour but when they were invited by king lion for his son’s wedding, they decided to decorate themselves for the occasion. The tortoise was given the task of making the dye to be used. Though he was slow, he was the most intelligent.
The big day was fast approaching but the tortoise had only managed to make one big pot of black dye. He called a meeting and they all decided to use the available dye to make various patterns in their skins.
The leopard was allocated the job of painting the rest of the animals. The zebra was the first on queue followed by the giraffe, then the donkey and all the other animals were to follow. The giraffe and the zebra were painted and they looked very beautiful.
Then the donkey’s turn came but he was undecided on the pattern to choose. The leopard decided to paint him like a zebra and got down to work. He had a long line along the donkey’s spine from head towards the tail. On reaching the tail, the donkey started giggling. The leopard continued and the donkey jumped and threw him his hind legs saying the brush was tickling and he could not contain himself any longer.
He had thrown his hind legs so hard that he hit the pot containing the dye. The dye spattered all over the animals on the queue. The cheetah got speckles all over his body, the leopard got spotted and the crow who happened to be passing by with an urgent letter for the king hanging on its neck was splashed by the dye which covered him the whole body apart from the neck where the letter was. On seeing this, the hyena started laughing but got a large splotch on his mouth.
All the animals rushed to the stream to try and wash out the dye but it was already dried and had become permanent. Nobody could get off the spots, streaks, speckles and splotches. And that is how the donkey was responsible for the various patterns we see on animal’s bodies today.

- Read the passage below and answer the questions that follow .(Solved)
Read the passage below and answer the questions that follow .
Cities and towns are experiencing massive population growth the world over receiving huge numbers of migrants ever year.
In 1950, urban population accounted for only 29 percent of the world population, according to the United Nations Educational Scientific and Cultural Organization (UNESCO). At the turn of the century, the figure had risen to 45 percent. This was enough to declare the Twentieth Century the century of urbanization and city life. Now the figure is projected to hit 70 percent by 2025.
In Africa, urbanization is most intense in Algeria, Tunisia and South Africa, which have more than 50 percent of their population living in urban areas. Generally, cities in the developing world are growing at a rate of 3.5 per cent per annum.
These figures indicate that there is a continuous massive movement of people from rural to urban areas worldwide. Driven by the desire for better living conditions, they flock to cities in droves in search of greener pastures. But, slowly the illusion disappears, and is replaced by harsh realities of urbanism: unemployment or underemployment, crime, poverty, hunger and life in the slums.
To cope with this fast – moving wave of rural flight requires new strategies for urban planning and the use of urban spaces. Thus urban planners, policymakers and governments seek pragmatic and timely ways of addressing this challenge. The process of urbanization transforms land use and farming systems, patterns of labour force participation, infrastructural requirements, and natural resource systems. When cities grow, their population expands, putting a strain on food production.
As a way of easing the food shortage, many urban households, particularly the poor, have taken to growing food on small plots. Today, if you take a walk through some of the residential estates in Nairobi such as Ngara, Eastleigh and Buru Buru, you might be forgiven for thinking that a green revolution is under way. And on the outskirts of the city, green – houses and ponds compete for space with small gardens planted with flowers, vegetables and fruits. Banana plants and palm trees dwarf wrought – iron gates, their green dotting the skyline, Kale, cabbage and maize gardens sprout in the middle of urban squalor. In this unusual rare blend, urban features and rural agrarian patterns are combined in a new form of settlement and one might call ‘garden cities.’
Although it is often not given much attention, urban agriculture is steadily increasing. The practice involves cultivating, processing and distributing food in and around a town or city. It also encompasses an array of activities including horticulture, aquaculture, animal husbandry and bee keeping
a) What are the challenges facing major cities and towns
b) What does the mention of 70% by 2025 reveal?
c) What do we learn about urbanization in Africa from the passage
d) Mention the reason for rural to urban migration
e) How are urban households easing the problems of food shortage?
f) What is meant by the term ‘garden city?’
g) In note form, list the influences of urbanization

- Read the passage below and then answer the questions that follow.(Solved)
Read the passage below and then answer the questions that follow.
Happiness arises largely from the mental qualities of contentment, confidence, serenity and active good-will. It includes the pain of losing as well as the pleasure of finding. It thrives best in a crowded life. The men and women who are recorded in history and biography as the most happy were with always somewhat to do than they could possibly do. Every waking hour of their lives was occupied with ambitious projects, literature, love, politics, science, friendship, commerce, professions, trades, their religious faith, and a thousand other matters. The secret of happiness may be found by making each of these interests count to its utmost as part of the fabric of life.
We need to avoid the extremes of sluggish placidity and feverish activity. we are not going to be satisfied with felicity which resembles that of a stone, unfeeling and unmoving, but will look back from future ears with sorrow and regret if we run to and fro, giving it what Socrates called ‘the itch’.
Happiness obviously includes two sorts of behavior: active and passive. We may say the active consists in searching and sharing, while the passive part is made up security and possession. Neither part is complete in itself, nor does neither yield full satisfaction if it is over-emphasized. Philosophers from the ancient Greeks to present day have been extolling a balanced life as the most happy life,and many unhappy people can, when they face the issue, trace their discontent to imbalance.
The recipe for happiness cannot be given in any single word, because its many virtues have to be combined in their proper quantities, at the proper times for proper purposes.
It is legitimate to seek happiness. We cannot help observing that while followers of some schools of thought are telling us to avoid seeking happiness; they intimate that if we do so we shall be happy.
The search requires a plan. We need to know what sort of happiness we seek, what the ingredients are, what our strongest wants are, and what we have to start with. We should train ourselves to keep the program me simple, and free from complications and side trips, to pay attention to little things to deflate quickly after being praised and to bounce back quickly after disappointment, to seize to create opportunities to put our special abilities to work, to seek excellence in everything we do, to remain modest and to review and revise periodically.
Most of us do not really have to seek far and wide. Happiness grows at our fireside, if we cultivate it.
a) According to the writer, what is the source of happiness?
b) What two sorts of behavior does happiness include?
c) What does the writer mean when he talks about a balanced life?
d) In a paragraph of about 30 words, summarize the things we must know as we search for happiness?
e) Explain the writers point in the last paragraph of the passage. (2mks)
f) The recipe for happiness cannot be given in any single word.
(Rewrite the sentence beginning: No single word....)
g)Identify and comment on the figures of speech used in the following:
(i) It (Happiness) thrives best in a crowded life.
(ii) ... as part of the fabric life.
