Ba nyiri mudasobwa bakunze kuboneka nikibazo cyo guhera, kandi buriwese arabikemura muburyo bwayo. Bamwe batezimbere sisitemu yo gukonjesha, kugura amakuru akenewe, abandi, ntibashaka kumara byinshi, gerageza kwigira. Uburyo bwa kabiri nibyishimo cyane kandi bisaba kubitekerezaho birambuye, kuva muriki kibazo hariho uburyo bwinjiza hamwe nubukwe ubwo aribwo bwose.
