error_type: Determiner Error
error_severity: 3

error_description: ① Determiner Error: According to grammatical rules, when no specific reference is needed, the noun 〈book〉 requires the indefinite article 『a』 before it; ② Preposition Error: A phrase indicating duration needs 『for』 to connect the time period, so it is added before 〈30 minutes〉 to mean 'for 30 minutes'; ③ Spelling Error: 〈mintunes〉 is misspelled; the correct spelling should be 『minutes』, meaning 'minutes'.
