    seon-saeng-nim-kke-seo mal-sseum-ha-syeoss-da: 'suk-je-reul kkok ha-se-yo.' hak-saeng-i dap-haess-da: 'al-ass-eo.', seon saeng nim kke seo mal sseum ha syeoss da: 'suk je reul kkok ha se yo.' hak saeng i dap haess da: 'al ass eo.'

    Informal ‘알았어’ correctly shows the student's understanding and acceptance.
