Take another look at the sentence:

Teresa was expecting a visit from her mother, so she spent the day cleaning the shelves of the refrigerator, scrubbing mold from the bathroom tile grout, and __________.

The blank requires a present participle phrase. You chose she removed dog hair from the sofa cushions, which is an entire main clause and thus causes a parallelism error.

Before you continue, review the rules for parallel structure.
