Mugucunga ingano yigihe cyo guhumanya no guhumeka mugihe cyo kubyara igice cya kabiri cyahumye, birashoboka kwemeza urwego runaka rwera mugihe kimwe kugabanya ibiciro byumusaruro nibidukikije. Ubu bwoko bwa pulp burakwiriye mugihe hari ibisabwa bimwe byera byera ariko ntibibe byera cyane, nkubwoko bumwe na bumwe bwihariye bwimpapuro zo kwandika, impapuro zo gucapa, nibindi.
3. Amashanyarazi
