1. Read the following passage carefully then answer questions that follow it by writing the letter of the correct answer in the booklet(s) provide.
     The beach at Lumley was a beautiful and impressive sight. The soft white sand fell away from rutted roadway in a gentle slope until it flattened out in a short plateu before dipping sharply to the sea. At the moment huge rollers were rushing inward to hurt themselves against the lower lip of the beach and expand their whistling froth in a fruitless struggle up the plateau.
     “Rather dangerous hare for bathing. Lets try further along, “he said.
About a kilometer beyond the golf court the beach curved gently in a shallow crescent. Several long boats manned by briskly padding Africans were darting to and from in among the gentler waves, while on shore scores of African men and women were gathered in long lines holding ropes which led to the edge of the water and out to sea.
     “This is really something you should not miss”, he said. “Lets get down there and watch the sun”
At close hand those on the beach were lined up, each like a tug-of-war team ready and waiting for its opponent. Each of these teams consisted of twenty or more men, women and children, most of them wet to the skin from contact with the waves, the young ones, boys and girls, were clad only in a kind of flowing loin-cloth. Some of these laughing children were truly beautiful; their smooth skins generously pearled by water droplets, eyes and teeth flashing in enjoyment. The young girls, some of them in their early or late teens, were full-breasted and completely unshy. Running up and down some short distance from the teams, shouting and waving his arms seaward was a large African clad only on the pair of uncolored shorts and a grotesque wide brimmed straw hat. His stentorian voice yelled instructions to the boat crew who paddled furiously or paused at his signals while those on the shore, at a word from him, hauled so vigorously on the lines that often several members of each team would tumble over in the sand to the delight of others.
     Suddenly the conductor for such he seemed to be, signaled rapidly seaward and all the boats immediately swung round to point inland, the paddlers working furiously as they raced simultaneously towards the beach. Meanwhile the line of pullers on the beach raced up the easy slope and soon the first ends of the nets appeared. Now ensured a frantic pulling on the ropes, hand-over-fist as they hurried to land the twisting, heaving, silvery catch, their voices raised in excited yells, laughter and exaltation.
     The boatmen raced their craft until they grounded, then leaped out to draw them up above the water-line before turning to lend a hand with the catch. And what a catch it was! Fish varying in length from two to three feet or more, fat succulent things which flopped and slithered as they were hauled to form a huge silvery pile which glittered in the rays of the slanting sun.
     As if informed by some kind of bush telegraph, several lorries and cars appeared along the road, honking their contributions to the din and disgorging groups of fish vendors and middle men.

 3. Read and summarize the following passage into 40 words;
     Women make up half of the world’s population. On that basis, one might expect that work and its rewards would be shared equally between men and women. Unfortunately, that’s not the case. In fact, in most countries, there is discrimination against women in terms of work rewards for work, ownership of property, legal rights, social opportunities and political responsibilities.
     In many societies today, especially where it is difficult to be financially independent, women are like unpaid servants in their own homes. It is women that take responsibility for raising the children and feeding and looking after their families’ health. In addition to their domestic work, many women also have to work on land or in factories to add to the family income. In Africa though women do 60% of the agricultural work, 50% of the caring of the animals and all the food processing, they have no right to any of the income from the sale of the produce or to ownership of land. Women are also responsible for collecting of firewood and freshwater. They make a great contribution to the development of their country through this upaid labour.

Answer all questions in this section
3. Read the following passage carefully and answer the questions that follow.
Historically the question of human rights has been constantly attracting international attention. In different places all over the world Tanzania included, human rights are being violated at different levels, ranging from the central government itself, local government, public institutions such as court and police, society and even at the level of the family and religion to mention few. Due to ignorance caused by lack of information and poverty, the victims of human rights violation may not be aware if their rights are violated or not. In some cases those who violate human rights do not know that they are violating them.
To combat the problem of violating human rights in Tanzania appropriate measures need to be taken. The first alternative is the on-going improvement of human rights education to the entire public. All citizens should be educated on human rights. Authorities such as police, people’s militia, executives, members of the parliament, councilors, teachers, employers and parents should know human rights.
The second steps is to know where to go when human rights are violated. In most cases violations occur to individuals. The court system and the police are the major organs that protect human rights. However, these organs may not help if human rights education is not provided. There is a need to form local human rights groups which will serve well even when an individual alone cannot get his/her rights. Such groups can be formed by students, women, workers, villagers or professionals, disabled, retired employers etc.
These groups will serve as regulators when any person or group is denied his/her rights. They will have a strong and common voice against any violation. This behavior will enable even law enforcers such as police, tax officers, magistrates and judges to be careful when doing their duties. This will ensure and enhance the commitment of lawyers and judges to interpret the laws accordingly. 
  1. Suggest a suitable title for the passage
  2. According to the passage, name two violators of human rights in our society
  3. In the context of this passage, outline two strategies that can be used to protect human rights in Tanzania
  4. In your views, what do you think is the role of the judiciary in protecting human rights in Tanzania? Give two points.
