Take another look at the sentence:
David was so hungry that he fought his brother for the container of leftovers, teared off the lid, and ate the cold meatloaf and congealed gravy right out of the plastic.
The second verb, teared, is incorrect. This sentence requires the simple past. Tore is the right form; teared is a spelling error.

Ate, the verb you chose, is perfectly correct. Before you continue, review the rules for irregular verbs.
