Soma makala yafuatayo kisha ujibu maswali.
Kiwango cha ufanisi wa taifa lolote lile hugezwa kutokana na hali ya miundomsingi. Mataifa sampuli hii hutenga fulusi si akali ya makadirio ya bajeti yake kwa miradi ya maendeleo. Nchi nyingi zinazoendelea hujikuta katika njia panda kwa mujibu wa utekelezaji wa sera amilifu za kukwamua chumi zao. Utawala wa Kenya umekuwa ukijikuna kichwa katika harakati za ujenzi wa nguzo hii ya ufanisi. Mbali na asasi za utabibu kuwa chache. Zile zilizopo ziko katika hali mahututi. Udufu huu umesambaratishwa zaidi na idadi kubwa ya madaktari na wauguzi wanaoendelea kugura tangu usimamizi wa huduma zao kuhamishiwa serikali za gatuzi, sikwambii changamoto zinazonyemelea sekta za elimu, utumishi wa umma na zaraa. Katika harakati za kupata suluhu, serikali imetoa rai ya kupunguza tija kwa watumishi wake. Rais, naibu wake na makatibu wa wizara wamekuwa vielelezo kwa kujitolea kunyoa 20% ya mishahara yao. Katika mdahalo wa kitaifa kuhusu matumizi ya mfuko wa umma ulioandaliwa na tume ya Mishahara nchini, rais alizirai bunge, mahakama, seneti, mashirika ya umma na magatuzi kudurusu mishahara kwa watumishi wake. Hii ni kwa sababu serikali inatumia 55% ya mapato ya ushuru ambayo inafasirika kama 13% ya mfuko wa umma kulipia mishahara. Kiasi hiki kimekuwa kikiongezeka kutoka shilingi bilioni 240 hadi bilioni 500 kwa muda wa miaka minne iliyopita. Wabobezi wa maswala ya iktisadi wamefichua kuwa hiki ni zaidi ya kiwango cha kimataifa cha 35% kinachotekelezwa na nchi zilizoendelea. Mbona tussige nchi za Malasya na Uswizi ambazo zimepunguza janguo kwa viongozi wao kwa 50%? Wataalam hawa wanashauri kuwa harakati hizi ni kama tone la suluhu kwenye bahari ya sintofahamu ikizingatiwa kuwa kupunguza mishahara ya wafanyakazi hasa wa ngazi za chini. Kutawanyonga katika uchumi ambao mfumuko wa bei umefikia kiwango cha kuvunda. Uhunifu unahitajika kupanua mfuko wa umma. Makadirio yanayotengewa wizara na shughuli nyingine za serikali zisizo za kimsingi yapunguzwe. Serikali pia inahitajika kuziba mianya ambayo kwayo darahimu lukuki hunywelea kutokana na ubadhirifu. Inatarnausha kutanabahi kuwa wizara ya usalama wa ndani haiwezi kuwajibikia matumizi ya shilingi milioni 548.7!
Wakenya walitoteza mamilioni kutokana na Benk Kuu ya Kenya kukaidi ushauri wa kisheria na kanuni za zabuni za kandarasi zinazohusu mitambo ya usalam na utengenezaji wa pesa. Si ajabu gavana wake Profesa Njuguna Ndung‘u alifunguliwa mashtaka ya utepetevu na matumizi mabaya ya mamlaka.
Wanaotolea nchi hii futuko wataweza tu kutua mori iwapo makabiliano haya na vyombo vya sheria yatawasukuma wahitifaki hawa wa chauchau nyuma ya kizimba. Waaidha, ziara za ughaibuni ambazo zilimpokonya mlipa ushuru milioni 348 mwaka wa 2013 pekee hazina budi kupunguzwa maradufu. Maafisa wa serikali lazima waghairi kutumia magari mazito yanayogubia mafuta. Inabainika kuwa gharama ya warsha na makongamano yanayonuiwa kuboresha ujuzi wa watumishi wa umma imeghushiwa licha ya utupu unaoambatana na mada zake.Serikali itaelezaje kauli kwamba imekuwa ikitumia shilingi bilioni 2 kuwakimu wafanyikazi hewa?Isitoshe, kuna wafanyikazi wengi wanaofanya kazi ombwe. Kwa mfano, makamishina wa magatuzi waliotumwa huko na serikali kuu wanatoa huduma zipi zisizoweza kutolewa na magavana? Ni ruya au halisi kuwa makdmishna wa Tume ya Mishahara nchini hulipwa marupurupu ya shilingi 400,000 kila mwezi kando na mishahara yao yenye minofu? Hii ni haramu ambayo lazima ilaaniwe.Ninashuku kuwa wakenya wangepigwa na mshtuko wa moyo iwapo marupurupu yanayohusishwa na taasisi nyingine za umma kama vile urais, mahakama na bunge yangeanikwa.

Soma makala yafuatayo kisha kisha ujibu maswali:-
Waajiri wengi wanazilaumu taasisi za elimu kwa kukosa kutoa wafanya kazi wenye ujuzi tosha, hasa wa kiteknolojia za kisasa kama kutumia kompyuta kutenda kazi mbalimbali. Hali hii imekuwa ya kuhuzunisha sana.
Ujuzi wa kuweza kutumia Kompyuta unaweza kumfaa mwanafunzi hata anapokosa nafasi ya kujiunga na chuo kikuu kwa vile anaweza kuendelea na elimu yake kupitia kwa elimu mtandao. Pia anaweza kufanya utafiti wa kina kupitia intaneti na kwa njia hii akaimarisha elimu yake.
Mojawapo ya njia ya kuimarisha elimu kuhusu maswala ya teknolojia ni kuanzishwa kwa mikakati mipya ya kufunza. Somo la Kompyuta laweza kuimarika mashuleni endapo kwanza walimu watahamasishwa juu ya faida za ujuzi huu.
Kwa kutumia Kompyuta kufunza, walimu wanaweza kufunza madarasa kadhaa katika kipindi kimoja bila kulazimika kuyahudhuria. Hii itapunguza kiwango cha kazi kwa walimu kwa vile watapata muda wa kufanya utafiti mpana. Aidha, watapata habari na ufahamu zaidi wa mambo kwa kutumia mitambo ya Kompyuta kutoka kwenye intaneti, kupitia tovuti.
Hata hivyo mipango hii inakabiliwa na changamoto kama vile bei za juu za mitambo na vifaa vya Kompyuta, ukosefu wa miundo msingi itakayowezesha utumiaji wa mitambo hii na ukosefu wa walimu waliohitimu somo la Kompyuta.
Pia, kuna tatizo la ukosefu wa nguvu za umeme hasa maeneo ya mashambani; vile vile, katika maeneo yaya haya, wanafunzi na wazazi wengi huvichukulia somo la Kompyuta kuwa gumu na linalofaa wakaazi na wanafunzi kutoka maeneo ya mijini na linalofaa wakaazi muhimu kwao mashambani.
Maswali
(a) Ipe taarifa uliyoisoma anwani inayoifaa
(b) “Hali hii imekuwa ya kuhuzunisha.” Ni hali gani inayozungumziwa katika aya ya 1?
(c) Ujuzi wa kutumia Kompyuta unaweza kumfaidi vipi mwanafunzi?
(d) Mikakati mipya ya kuimarisha elimu kuhusu maswala ya teknolojia inakabiliwa na
vizingiti vipi?
(e) Taja manufaa mawili ambayo mwalimu anaweza kupata kutokana na ujuzi wa teknolojia
ya Kompyuta
(f) Andika msamiati mwafaka zaidi kwa maneno yafuatayo:

Soma makala yafuatayo kisha ujibu maswali.
Takwimu za hivi punde zinaonyesha kuwa maradhi ya saratani imejifaragua na kuwa miongoni mwa senene kuduku duniani maadam inatishia kuupiku ukimwi. Wagonjwa wanoendelea kuyasalimia amri wanaelekea kufikia kiwango cha kutisha.Licha ya tawala nyingi duniani kuwekezea tafiti anuai za kuyapindua, miale ya welewa wa kiini chake bado ni hafifu ajabu. Wataalam wa utabibu wanaeleza chanzo cha saratani kama mgawanyiko usio wa kawaida wa chembechembe za damu katika viungo vya mwili vinavyohusika. Viungo huanza kukua kwa kasi isiyo ya kawaida.Japo uvumbuzi unaonyesha kwamba kuna uwezekano mkubwa kwa watu wa umri wa makamo kuambukizwa ugonjwa huu. Wazee wamo hatarini zaidi.Hata hivyo vimeshuhudiwa visa vingi ambavyo hata watoto wachanga huathiriwa pakubwa.Saratani ya tezi-kibofu. Ya koromeo nay a mapafu ni baadhi ya aina zinazowaathiri wanaume. Saratani ya tezikibofu huwasogelea zaidi mabuda wa umri wa miaka zaidi ya sitini. Kwenda haja ndogo kila mara. Ugumu wa kupitisha mkojo, ugume wa kuanza au kumaliza kukojoa, damu kwenye mkojo na maumivu ya mgongo ni baadhi ya dalili zake. Mwishowe, tezi-kibofu huzidi kuwa kubwa na kufungia mkojo kutoka. Kansa zinazowalenga sana wanawake ni pamoja nay a nyumba ya uzazi, mlango wa uzazi na maziwa. Kansa ya maziwa huwachachawiza zaidi wanawake wenye umri wa miaka thelathini na mitano au zaidi. Dalili ya awali ni uvimbe unaohisika kwa ndani na maziwa kutoa usaha. Inaenea haraka na kuviambukiza viungo vya ujirani mathalani mapafu na ini. Saratani ya mlango wa uzazi inaambukizwa na virusi vinavyoita papolloma. Virusi hivi hupata mwanya iwapo mwanamke aliaza mahusiano ya kimapenzi katika umri mdogo,akiwa na wapenzi wengi, akiwa matumizi wa dawa fulani za kupanga uzazi na apulizapo moshi wa sigara. Inapendekezwa kuwa ukaguzi wa ada ufanywe ili kuugundua kabla haujasambaa kutokana na kauli kwamba mwanzoni hausababishi uchungu wowote. Ukaguzi wa kibinafsi kwenye viungo vilivy na uwezekano mkubwa wa kuambukizwa kisha jambo lolote lisilo la kawaida kama vile uvimbe na ugumu wa kumeza liwasilishwe mara moja kwa daktari. Ushauri zaidi unahusu aina ya vyakula na mitindo ya kisasa ya maisha. Vyakula vilivyosheheniwa na protini zipatikanazo katika nyama na mayai ni miongoni mwa vyakula hatari. Vyakula vya kiasili kama mboga, miwa, matunda, mafuta yanayotokana na mimea na nyama nyeupe hupendekezwa. Uvutaji wa sigara, unywaji pombe, na baadhi ya vipodozi vyenye zebaki huweza kurutubisha uwezekano wa kuambukizwa saratani.
Ijapokuwa saratani ni kama sikio la kufa lisilosikia dawa, ni muhimu wawele wazibe ufa kabla ya kuangukiwa na ukuta usioweza kujengeka tena. Ikigunduliwa mapema. Maradhi haya huweza kudenguliwa kutumia tibakemikali, tabamiale, chanjo dhidi ya baadhi ya virusi vya saratani, upasuaji wa viungo vilivyoathiriwa na dawa za kupunguza makali yake. Utafiti wa kina uliofanywa na kukamilishwa mwezi wa Machi, mwaka wa 2014 na madktari wa Hospitali ya Kitaifa ya Kenyatta kwa ushirikiano wa wengine kutoka Uingereza umegundua kuwa dawa aina ya Lopinavir inyotumiwa kupunguza makali ya ukimwi ina uwezo wa kukabiliana na maradhi haya. Uchunguzi uliofanyiwa wawele baada ya muda Fulani wa uwekaji wa dawa hii kwenye mlango wa uzazi ulibainisha kuwa chembechembe za saratani huangamizwa na dawa hii. Ni jambo la kutia moyo kuwa harakati za kukabiliana na janga la ukimwi zinaelekea kutoa sulhu kawa maradhi haya ya kansa.Inakuwa shani inaposadifu kuwa nuhusi iliyowahi kutokea katika mapisi ya siha ya insi imekuwa kitivo kinachopaswa kuenziwa. Hakika hizi ni harakati zinazostahili kupongezwa na kuzidishwa iwapo zimwi hili litafukiwa katika lindi la usahaulivu.
