She has went to school last Monday.

Correction: Past Simple Tense

This sentence has an error because 'has went' is an incorrect form. The auxiliary verb 'has' indicates the Perfect tenses, but 'went' is the past tense of 'go', not the past participle. The correct past participle is 'gone'. However, the phrase 'last Monday' clearly indicates a specific point in the past, which requires the Past Simple tense.

Corrected Sentence: She went to school last Monday.

Explanation: The Past Simple tense is used for completed actions at a specific time in the past. 'Went' is the past tense of 'go'. If the sentence intended to use the Present Perfect, it should have used the past participle 'gone' and removed the specific time reference or used a different structure.
