Take a look at the sentence again:
When Richie jammed the photocopier for the eighth time, Sharon, the administrative
assistant, picked up a heavy stapler and __________ it at his head.
The sentence requires the past tense of throw, an irregular verb. Threw is the simple past form.
| Verb | Simple Present | Simple Past | Past Participle |
| throw | throw(s) | threw | thrown |
Through, the form you chose, is not a verb; it is a preposition. Before you continue, review the rules for irregular verbs.
