Here is the item:
Keila knew that she had many misspelled words in her essay, so she digged around in her book bag, searching for her dictionary. She found instead a chocolate bar, which she ate, hoping that the sugar rush would help her brain remember the right combination of letters.

The second verb, digged, is incorrect. As you know, the sentence requires the simple past of dig, an irregular verb. Dug is the correct form; digged is a spelling error.
