. ubugari.

Duhereye ku isesengura ryavuzwe haruguru, urashobora kubona ko uruziga rufunze hano rwananiwe kubera inkombe yasigaye kumuhanda wimbere mugihe cyo gusya impeta yimbere.Kubwibyo, mugihe cyo gusya inzira yimpeta yimbere, ubugari bwuruziga rugomba gutoranywa neza kandi umwanya wo gufatira kumurongo wimbere wimbere hamwe ninziga yo gusya bigomba kuba byukuri kugirango wirinde kubyara impeta yimbere yimbere, bityo kwirinda kunanirwa hakiri kare.
