Here is the sentence:
Because Kerri Ann __________ all of her biology homework, she spent the rest of the evening with her friends. The next morning, when Dr. Wright passed out the difficult pop quiz, Kerri Ann realized that her books should have been her only company.
The blank requires a past tense form of do, an irregular verb. You chose had done, the correct form. Good job!
