P3: Na di-reducer tsa tshepe e sa ruseng di theko e boima haholo?

E, di-reducer tsa tshepe e sa ruseng hangata di bitsa tjhelete e ngata empa di fana ka kganyetso e phahameng ya mafome le bophelo bo bolelele ba tshebeletso.

10. Qetello

Lisebelisoa tsa ho fokotsa liphaephe li ka bonahala li le bonolo, empa li bapala karolo ea bohlokoa moralong oa sistimi ea liphaephe.
Ho tloha ho di-reducer tse shebaneng le tse sa bonahaleng ho isa ho thepa e fapaneng, maemo le mefuta ya kgokelo, se-reducer se seng le se seng se sebeletsa morero o itseng.

Ka ho utloisisa hore na ho na le mefuta e mekae ea li-reducer tsa liphaephe le hore na li fapana joang, baenjiniere le bareki ba ka etsa liqeto tse nang le tsebo tse ntlafatsang polokeho ea sistimi, bokhoni le ho tšoarella.

Haeba o batla di-reducer tsa diphaephe bakeng sa merero ya diindasteri, ho kgetha mofuta le maemo a nepahetseng ke senotlolo sa tshebetso ya nako e telele le ho latela melao.
