Because
Just because I smile and smile
And happiness is not my coat
And my song tuneful and strong
Though you send me down below
Into unlievable regions
Of the blue rocks of the earth
You think then I am a gatepost
Numb to the stab of pain
Just because of the laugh of my lips
And my eyes covered in respect
Pants rolled up above the knees
And my dark hair all down dun-coloured
And thick with the road side dust,
My hands swinging a pick
And the back stripped out of my shirt.
You think I'm like a stone
And don't know what it is to die
Because at the fall of dark
When I've loosened the chains
Of my long day's labour
And I fall in with my brother,
Stamping the ground in a tribal dance
And we sing songs of old times
That stir up our fighting blood
Driving away all our cares
For that you think I'm a beast
That breeds its kind and dies
Because I seem to you simpleton
Knocked over by plain ignorance
And laws beyond my understanding
Except may be you rob me
And the house built for myself
Under the hand of a rock
A hut of grass for my home
My clothing an empty sack
You think I'm just an ant heap
And not one tear have I in me
To drip out from my own heart
And run over the pure hands
Of souls who see all.

Read that passage below and answer the questions that follow.
Even though tattoos are sometimes associated with rebellion, they have longstanding history among
communities around the world. Tahitians, for instance used tattoos as a permanent way of preserving their
culture and to show social ranking. Early Christians, on the other hand, often had the sign of a cross tattooed on their bodies, particularly their faces and arms, representing a permanent mark of the believer's faith.
The word 'tattoo' is derived from a Tahitian word tatau that means to mark. Tatau has been suggested to be the onomatopoeic sound tap, tap, tap made by the tapping of a tattoo instrument as it works on skin while 'au' is associated with the cry of pain a person gives when being tattooed.
The first ever tattoo to be found on a human being was found on a mummified iceman in 3,300BC with 58
tattoos on his body, which contained lines and dots. This is nothing, however, compared to Scottish Tom
Leopard, recorded as the world's most tattooed person, with 99.9 per cent of his body covered in leopard
skin design. Guinness world records record that the only part of his body that remained untattoed is the skin between his toes and inside of his ears.
When receiving a tattoo, the skin is pierced between 50 to 3,000 times per minute by a needle in the tattoo machine. Most tattoo machines consists of four parts: the needle, the tube that holds the ink, an electric motor, and a foot pedal that controls the movement ; almost similar to how a sewing machine works.
Sterilization and disposable materials are crucial to tattooing because tattoos are created by thousands of puncture marks to the skin, each of which could be infected. The autoclave is a safe popular way to sterilize any tattoo equipment that is not disposable. A combination of heat, steam and pressure kills all bacterial and organisms to prevent infection.
In the late 18th and early 19th centuries, tattoos were dangerous to have. European 'head hunters' caused a
terror by collecting tattooed Maori heads. As the odd sport became popular, more Moaris were murdered to
meet the demand. In the time, slaves began being tattooed so that their heads could be cut off and sold.
Luckily, however, Christian missionaries in the cook Island condemned the practice of tattooing quoting
the Bible “… do not cut your bodies for the dead or put marks on yourself….” They tried to stamp out the
custom going as far as trying to remove tattoos by rubbing the skin with sandstone in a practice that was
known as ' holy stoning'. This was the primitive forerunner to modern tattoo removal known as
dermabrasion, where the skin is 'sanded' to remove layers. Dermabrasion has now largely given way to
laser surgery as a popular means of tattoo removal.
While tattoos bring colour to humanity, research has shown that unclean tattooing practices can transmit
diseases such as hepatitis B. Some pigments used in tattoos contain metals that can cause pain during a
Magnetic Resonance Imaging (MRI) test, or even affect the resulting MRI image. Because of the possible
negative effects tattoos pose to humans, those keen on getting one have to be very careful before they get
one. That said, it is important to note that presently, many tattoo artists earn a good living out of the art.
(a) From paragraph one, state two historical uses of tattoos.
(b) According to the writer state the origin of the word tattoo.
c) What is most striking about Tom Leopard.
(d) What was the risk associated with tattooing in the 18th and 19th centuries.
(e) State two modern ways of tattoo removal.
(f) Many tattoo artists earn a good living out of the art. (Add a question tag)
(g) In note form state the negative effects of tattooing.
(h) What are the benefits of tattooing as suggested in the passage?

Read the following poem carefully and then answer the questions that follow:
The mask
We wear the mask that grins and lies
It hides our cheeks and shades our eyes
This debt we pay to human guile;
With torn and bleeding hearts we smile,
And mouth with myriad subtleties.
Why should the world be over-wise,
In counting all our tears and sighs?
Nay, let them only see us while
We smile, but O great Christ, our cries
To thee from tortured souls arise
We sing, but oh the clay is vile
Beneath our feet, and long the mile
But let the world dream otherwise
(Paul Lawrence Dunbar).
QUESTIONS
1. Describe the Rhyme Scheme of the above poem.
2. Identify ANY other sound patterns used in the poem. What is their effect?

Fill in the following gaps with the most appropriate word
The setting of a story ________ to the time and place where the story takes place. The setting may shift
from one place to _________________________as the story progresses and end somewhere else, or it
might move elsewhere and come back to the _____________________________ place, hence completing
a full circle. Sometimes the setting _________________ be static (no change. Time is also important for
the setting. This could be told in the story, or could be ____________________________ by the events in
the of the story. For example ,if the story ______________________around a modern setting, with modern
buildings and technological devices, this alludes to the time of setting-i.e. the recent past.
__________________________ if the show grass-thatched huts as dwelling places of the character, this
could be an indication that either the setting is in the____________________________ of the rural areas
,or the story was written was some time __________________________the past
It is important to _____________________________ the setting of a story as this helps us to understand
the theme, the behavior and attitudes of the characters in the story better.
