error_type: Determiner Error
error_severity: 3

error_type: Verb Choice Error
error_severity: 3
error_description: Verb Choice Error: Based on context and sentence meaning, the intended action is the mother checking the homework, not simply seeing it. The verb 〈see〉 means 'to see' or 'to look at' but does not include the meaning of 'to check' or 'to inspect'; thus, there is a verb choice error here, and 〈see〉 needs to be changed to 『check』 to fit the context and meaning.

correct_sentence: After that, I am going to help my mother to do housework.
