1. Soma kifungu cha habari kifuatacho kisha jibu maswali yanayofuata:

Karibu masikio ya watu wa mahali pengi yalijaa habari za Karama na mashtaka yake. Umaarufu wake wa ghafla ulizungumzwa karibu na mbali. Mtu yeyote wa desturi anapozuka katika umaarufu, huyavuta masikio na macho ya watu wengi kwa sababu jambo kama hili hutokea nadra sana kwa watu ambao bahati mbaya imeshughulika kuwaweka nyuma. Kwa hiyo, siku ya tatu ya baraza ilihudhuriwa na mfalme, watu wenye vyeo mbalimbali, pamoja na nusu moja ya umati mkubwa wa Kusadikika. Fikra zilizochanganyika ziliushika umati huu. Baadhi ya watu walimwajabia Karama wakamhesabu kama mtu bora wa karne yao. Hawa walitumaini ataokoka lakini wengine waliwaza kuwa Karama alikuwa kama mjinga aliyekuwa akicheza na hatari kubwa iliyofunua taya mbele yake.

Waliokuwa wakimtazamia kuokoka walikuwa na wasiwasi wao; na wale waliokuwa wakimtazamia kuanguka walikuwa na fadhaa yao. Walakini hapana mtu hata mmoja aliyepata kulisema wazo lake.

Bila ya kujua alivyoajabiwa Karama aliendelea kusema mbele ya baraza, “Watu wanaoteswa ndio wanaoyajua mateso yao.” Kusadikika ilikuwa chini ya mateso makubwa sana. Maisha yao yalizungukwa na maradhi na mauti, uadui usiokwisha, nchi iliyokaribia kugeuka jangwa na mwamba na madhila mengine mazito yaliyowakabili watu. Wanakusadikika walitaka faraja katika mateso haya. Kila jitihada ilijaribiwa ili kuirekebisha saa ya maendeleo ya nchi, lakini mara kwa mara majira yake yalirudishwa nyuma. Kama hili lilifanywa kwa makosa ama kwa makusudi ni siri iliyo ng’ambo ya fahamu zangu hata sasa. Lakini kama siri njema hufichika, ile iliyo mbaya haifichiki hata kidogo. Uchaguzi wa wajumbe ulikuwako lakini hathibitisho ya matokeo ya ujumbe hayakupatikana.

Kusadikika iliishi kuona mjumbe baada ya mjumbe kuadhiriwa na kuadhibiwa vibaya. Kama washauri hawakudhuriwa na hili lakini watu wengine walidhuriwa sana. Kazi njema za wajumbe wawili zilipotea bure. Manung’uniko ya lawama hii yalikuwa katika hewa yote ya Kusadikika.

Hili lilipotokea serikali iliombwa ima faima kufanya ujumbe mwingine. Basi mjumbe wa tatu alitakikana ajitolee mwenyewe kwa ujumbe wa Kusini. Wito wa mjumbe wa tatu uliitikiwa na Kabuli; mtu mwenye busara, haya na mcheshi. Yeye alipatikana upesi kabisa kuliko ilivyokuwa kwa mara ya pili na ya kwanza. Misiba ya Buruhani na Fadhili ilikuwa mikubwa ya kutosha kuikongoa mioyo ya bidii katika bawaba zake. Kabuli aliyajua haya yote lakini alikuwa mtu wa moyo wa namna nyingine kabisa. Alikuwa na bidii kubwa kama ile ya siafu athubutiye kukivuka kijito kwa daraja iliyofanywa kwa maiti ya siafu wengine walioelea majini huko na huko. Maji yalijulikana kuwa na asili ya rutuba, mvuke na umeme. Nguvu nyingine za namna mbalimbali zipo pia katika maji. Kama siafu mdudu mdogo na kipofu wakati mwingine haogopi kuzikabili nguvu hizo pamoja na hatari zake kwa sababu njema, basi ni dhahiri kuwa viongozi wa wanadamu wanapoteswa bure bidii za wafuasi wao hutanuka ajabu.

Hapana tishio liwezalo kuukomesha mwendo huu. Kwa hakika utafululiza kuwako duniani mpaka mateso yakome kabisa, na labda wakati huo dunia hii itakuwa njema kama itamaniwavyo kuwa.

Buruhani na Fadhili walitoa sadaka zao bora ili kuyahimiza majilio ya wakati uliotakikana sana. Kabuli aliwaona watu wawili hawa kama wafadhili wakubwa wa ulimwengu. Alitaka kuwa mshirika wao kwa thamani yoyote ya maisha yake.

Kama ilijulikanavyo, Kusini na upande wa dunia yatokako matufani makubwa na baridi kali sana. Kabuli aliyakabili mashaka haya bila ya kigeugeu. Naam, alikuwa kama mtu aliyekuwa akinywa uchungu bila ya kigegezi. Mara mbili alikamatwa akafanywa mahabusu.

Maswali

(a) Eleza maana ya maneno yafuatayo kama yalivyotumika katika kifungu cha habari:

4. Ima faima
5. Kigeugeu
6.  Kigegezi.

(b) Eleza mchanganyiko wa fikira walizonazo wana wa Kusadikika kuhusu Karama.

(c) Kwanini bidii ya mjumbe wa Kusini imelinganishwa na bidii ya siafu? Toa sababu mbili.

(d) Ujumbe wa mwandishi wa kifungu hiki unahusu nini?

SEHEMU C (Alama 45)

Jibu maswali matatu (3) kutoka katika sehemu hii.

8. Andika insha isiyozidi maneno mia tatu (300) na isiyopungua mia mbili na hamsini (250) kuhusu faida za televisheni kwa jamii.

8. Read the passage below carefully then answer the questions that follow.

English Language seems to be a problem to both teachers and students in Tanzania although it is an official language. It is taught as a subject in primary schools and is used as the medium of instruction from secondary schools to higher education levels.

In recent years, the language has been a barrier in academic performance among many students. It acts as an obstacle to some of the students toward learning new concepts intended since they fail to understand what is taught in the classroom by using English Language. As a result they finish a certain level of education without having the required skills and competences.

Some measures should be taken in order to solve the existing problem. It is suggested that Kiswahili should be used as a medium of instruction in all levels of education because it is the National language and it is well understood by Tanzanians as compared to English Language. It has been proven through various researches that, people understand better when they learn in the language they know.

There are some prevailing wrong perceptions that, Kiswahili has limited vocabularies and it is not self-sufficient when it comes to scientific and technological issues. This is a very wrong perception since any language in the universe has ability to borrow and incorporate words from other languages. However, there is no language which is self sufficient by itself.

Questions:

(a) Suggest the suitable title for the passage with about four to ten words.

(b) How could the problem of language of instruction be solved in Tanzania? Explain one means.

(c) Why has English Language been a problem in Tanzania? Give one reason.

(d) In your opinion, which language between Kiswahili and English should be used as a medium of instruction in all levels of education in Tanzania? Limit your response to one point.

SECTION C (45 Marks)

Answer three (3) questions from this section.

9. Imagine that you are in a debate club, argue for the topic "Trafficking of girls from rural to urban areas to be employed as house girls (housemaids) should be stopped" in not less than 250 words.

Hallow heads torture me with ignorance,

Blind eyes harass me .with darkness, Deaf ears tire me with silence,

Dumb voices deafen me with gibberish,

Black minds confuse me with emptiness

And, above all,

There is power and command.

With wits and ears and eyes,

I have speech and strong mind,

But I remain weak and powerless.

They fight me they kill me.

It is a fight to bring me down to silence, To darkness and gibberish, to ignorance. And through brainwashing, to emptiness.

All right, my friends,

It's a battle and I will fight it

Ears and wits and eyes and speech, And strong conscience:

These are my weapons.

And I fight to the last cell.

3. Read the following passage and then answer the questions that follow.

Natural resources can be classified as non­renewable and renewable. Non­renewable or exhaustible resources such as fossil fuels, copper, and gold exist in fixed amount in various places in the earth crust. They can be used completely or economically depleted to the point where it costs too much to get what is left, when 80 percent of its total estimated supply has been removed and used.

A renewable resource is one that can theoretically last forever, because it is replaced through natural process. Examples are trees in the forest, grasses in grasslands, wild animals, fresh surface water in lakes and rivers, fresh air and fertile soils. The earth most valuable resources, is its diversity of potentially renewable forms of life. But over use can convert renewable resources to non­renewable by using them faster than they can be replenished.

Some non­renewable resources can be recycled or reused to extend supplies. Iron, aluminium, glass, for example, can be collected, remelted, reprocessed and made into new products. Also to avoid excessive use of resources, recycling of papers products needlessly burned or thrown away, reduce timber needs for the paper industry. Domestic refuse can be used to generate power particularly for local districts heating and lighting schemes, though care must be taken when incinerating to avoid air pollution problems.

Other non­renewable resources, such as fossil fuels (coal, oil and natural gas), cannot be recycled or reused. When burned, the high quality useful energy in these fuels is converted to low quality waste heat and exhausted gases that pollute the atmosphere.

Questions

(a)  From the passage, identify two resources which can be replaced through the natural process.

(b)  State three merits of recycling non­renewable resources.

(c)  List down three environmental problems associated with burning of fossil fuels.

(d)  Explain the condition under which renewable resources cannot be renewed.

(e)  Suggest two measures to promote sustainable use of natural resources.

4.   Briefly explain the importance of family stability by giving five points.

5.  Outline five traditions and customs which affect the reproductive health of women in Tanzania.

6. Briefly explain the main five functions of the Central Bank of Tanzania (B.O.T)
