Q1. U sebelisa lisebelisoa life bakeng sa lipeipi tsa hau tsa ts'ireletso ea mollo?

Li-hose tsa rona tsa mollo li entsoe ka tšepe ea boleng bo phahameng, ho netefatsa matla le ho tšepahala litšebelisong tse sa tšoaneng.

Q2. Ke tseba joang haeba piping ea hau ea tšireletso ea mollo e loketse litlhoko tsa ka?

Re fana ka mefuta e mengata e fapaneng ea boholo ba liphaephe le litlhaloso. Sehlopha sa rona se ka u thusa ho lekola litlhoko tsa hau le ho khothaletsa tharollo e molemohali.

Q3. Ke maemo afe a tšireletso ao lihlahisoa tsa hau li li latelang?

Liphaephe tsa rona tsa ts'ireletso ea mollo li finyella litekanyetso tsa machaba tsa tšireletso, ho netefatsa hore lipalangoang tse ka tšeptjoang tsa thepa e kotsi.

Q4. Na lipeipi tsa hau tsa ts'ireletso ea mollo li ka etsoa ka mokhoa o ikhethileng?

E, re fana ka likhetho tse tloaelehileng ho finyella litlhoko tse khethehileng tsa morero ho kenyeletsa boholo, botenya le ho roala.

Q5. Nako ea ho etella pele ea taelo ke efe?

Linako tsa thomello lia fapana ho latela boholo ba odara le litlhaloso, empa re ikitlaelletsa ho tlisa kapele ntle le ho senya boleng.
