Here is the sentence:
Christine wrang her hands as she listened
to Dr. Armour's lecture about tardiness. Although Christine
swore to her math teacher that she would
never be late again, everyone in the class knew that when the alarm clock
rang the next morning, Christine would hit
the snooze button one time too many.
The first verb, wrang, is the problem. As you know, the sentence requires the simple past. Wrung is the correctly spelled form.
