error_sentence: Last Saturday, I get up early.
correct_sentence: Last Saturday, I got up early.
error: get
correction: got
error_type: Verb Tense Error

correct_sentence: Then, I ate breakfast.
error: the brankfast
correction: breakfast

error_type: Punctuation Error

error_type: Verb Tense Error

correct_sentence: I think I had a good weekend.
error: weekends
correction: weekend
