First, her mom asked her to help clean the house in the morning, and then she had to go to the dentist’s at 12:30. Two hours after that, she met Julia to help her with her science. Then she had to go to soccer practice with her brother at 4:30, and her mom asked her to cook dinner for the family at 5:30. Then, she had to do her history homework.
