Take another look at the sentence:

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.
