In this article waxaan ku tusi doonaa sida loo Waxaad u habayn kartaa jawaabta tooska ah ee xoogga sirta ah adiga oo ku daraya xeer cusub dab-damiska. InTrust waa ururinta, falanqaynta iyo kaydinta xogta aan habaysanayn, taas oo horeba u lahayd boqollaal falcelino hore loo sii qeexay oo ku saabsan noocyada kala duwan ee weerarrada.
Quest InTrust waxaad ku habeyn kartaa ficillada jawaabta marka sharci la kiciyo.
