<prompt> Qedela le nkulumo elandelayo: Ikhono lamagciwane lokucekela phansi izinhlanganisela ezihlukahlukene eziphilayo liyamangalisa futhi liye lasetshenziswa ekulungiseni imfucuza nasekusebenziseni izinto eziphilayo. Amabhaktheriya akwazi ukugaya ama-hydrocarbon asemanzini avame ukusetshenziselwa ukuhlanza amafutha acitshile.
