Natiijada casharka

Waxaan qeexi karaa oo cabbiri karaa tusaalooyinka kala duwanaanshaha aan joogto ahayn iyo kala duwanaanshaha joogto ah ee sifooyinka.

Hordhac

Casharkani waa "Kala-duwanaanshaha Joogtada ah iyo kan Aan Joogtada ahayn: Farsamo", waxaana ka tirsan cutubka "Kala-duwanaanshaha, Farqiga u Dhexeeya Noolaha Isku Nooca ah". Waa inaad hore u garanaysaa fikradda guud ee kala-duwanaanshaha iyo sida nooluhu u kala duwan yihiin.
