Intambara zo mu mahanga zirakomeje, ariko ubukungu bw’imbere mu gihugu bukomeje gushyiraho politiki nziza, kandi ku ruhande rw’inganda, ibiciro by’amabuye y'agaciro byazamutse cyane. Bifocals yazamutse bitewe no kwiyongera kwinshi mugihe cyizuba, inkunga yibiciro yarakomeye, kandi ibiciro byibyuma byakomeje kuzamuka. , ubwoba bwibikenerwa byigihe kinini byarushijeho kwiyongera, ibikorwa byo kuzuza isoko byiyongereye, umusaruro wibyuma bya buri munsi wagabanutse, ibicuruzwa bitumizwa mu mahanga byagabanutse, ikindi cyiciro cya cyamunara cyubutaka cyatangiye, kandi isoko ryibibanza rihamye kandi rirakomeye. Urebye neza, ibiciro byibyuma biteganijwe ko bizahoraho kandi bikomeye ejo.

Inganda za Sanon muri iki gihe zifite imiyoboro ikurikira mu bubiko:
