error_description: ① Nonfinite Verb Form Error: Based on the sentence's meaning, it is in the present continuous tense, so the verb 〈try〉 following the linking verb needs to be in the present participle form 『trying』 to comply with the present continuous tense grammar rule; ② Preposition Error: According to English fixed expressions and the prompt requirements, the verb 〈try〉 needs to be paired with the preposition 『on』 to form the complete phrasal verb 『trying on』, meaning to try clothes on; therefore, 〈try〉 is changed to 『trying on』.

error_severity: 5
error_description: ① Spelling Error: According to the sentence's meaning, it intends to express the object of the action, and 'wait' requires a preposition when followed by an object; thus, 〈fir〉 is a misspelling of 『for』 and needs to be corrected to 『for』 for the sentence to make sense; ② Noun Possessive Error: According to English grammar rules, since 〈mother〉 in the sentence refers to Linda's mother, to ensure clarity, 『Linda's』 needs to be added before the noun 〈mother〉 to form the possessive case.
