Take another look at the sentence:
When Mom __________ out the kitchen rug, dog hair, bread crumbs, coffee grounds, and spaghetti noodles flew through the air and dusted the sidewalk.
The sentence requires the past tense of shake, an irregular verb. Shook is the simple past form.
|Verb||Simple Present||Simple Past||Past Participle|
Shaked, the form you chose, is a spelling error. Before you continue, review the rules for irregular verbs.
