error_type: Noun Error
error_severity: 4
error_description: ① Noun Possessive Error: According to English grammar rules and the prompt requirements, the intended meaning here is 'the store's clothes are very cheap', the original phrase 〈Mr. Cool's Clothes Store〉 needs to be in the possessive form to indicate ownership, therefore 〈Mr. Cool's Clothes Store〉 is changed to 『Mr. Cool's Clothes Store's』 to fit the context; ② Noun Error: According to the context, the intention is to express 'the clothes are very cheap', the original subject 〈Mr. Cool's Clothes Store〉 refers to the store itself and lacks the object of the sale, therefore 『clothes』 needs to be added to fit the context; ③ Subject-Verb Agreement Error: When the store itself is the subject, the linking verb is singular, but after changing to the plural noun 'clothes', 『are』 should replace 『is』.

error_sentence: The Mr. Cool's Clothes Store is very crowed and loudly.
correct_sentence: Mr. Cool's Clothes Store's clothes are very cheap. Mr. Cool's Clothes Store is very crowded and loud.
error: The
error_type: Determiner Error
error_severity: 2
error_description: Determiner Error: According to English grammar rules, a proper noun that already includes a possessive structure ('s) does not need an additional determiner like 〈The〉, as it would lead to a double determiner error. Since 〈Mr. Cool's Clothes Store〉 is a proper noun with a possessive, 〈The〉 should be deleted to comply with grammar rules.

error_sentence: The Mr. Cool's Clothes Store is very crowed and loudly.
correct_sentence: Mr. Cool's Clothes Store is very crowded and loud.
error: crowed and loudly
correction: crowded and loud
error_type: Adjective Error
error_severity: 4
error_description: ① Spelling Error: Based on the sentence meaning, the intention is to express 'crowded', so 〈crowed〉 is a misspelling of 『crowded』; it needs to be changed to 『crowded』 for the sentence to make sense; ② Adjective Error: According to the context, the intention is to express 'loud', which requires an adjective. The original word 〈loudly〉 is an adverb and should be changed to the adjective 『loud』 to fit the context.

error_sentence: What kind of do you want?
correct_sentence: What kind of clothes do you want?
correction: clothes
error_type: Noun Error
error_severity: 2
error_description: Noun Error: According to English grammar rules, 〈What kind of〉 must be followed by a specific noun to form a complete phrase. The original sentence lacks a noun after 〈What kind of〉, so 『clothes』 needs to be added after it to express the complete meaning.

error_sentence: And very beautiful shoes and shirt in the Mr. Col's Clothes Store.
correct_sentence: And there are very beautiful shoes and skirts in Mr. Cool's Clothes Store.
correction: there are
error_type: Sentence Structure Error
error_severity: 4
error_description: Sentence Structure Error: According to English grammar rules, a clause needs a subject and a verb. The original phrase beginning with 〈very beautiful shoes〉 lacks a subject and verb; 『there are』 should be added to form an existential sentence structure, complying with grammar rules.

error_sentence: And very beautiful shoes and shirt in the Mr. Col's Clothes Store.
correct_sentence: And there are very beautiful shoes and skirts in Mr. Cool's Clothes Store.
error: shirt in the Mr. Col
correction: skirts in Mr. Cool
error_type: Noun Error
error_severity: 1
error_description: ① Noun Error: According to the prompt requirements, the intended meaning here is 'skirts', so the original word 〈shirt〉 should be changed to 『skirts』 to meet the prompt's requirement; ② Determiner Error: According to English grammar rules, a proper noun that already includes a possessive structure ('s) does not need an additional determiner like 〈the〉, as it would lead to a double determiner error. Since 〈Mr. Col's Clothes Store〉 is a proper noun with a possessive, 〈the〉 should be deleted to comply with grammar rules; ③ Spelling Error: Based on the prompt, the intention is to express 『Mr. Cool』, therefore 〈Mr. Col〉 is a misspelling of 『Mr. Cool』; it needs to be changed to 『Mr. Cool』 to correctly represent the store name.
