Match each base form to its past simple form.

Explication

These past-simple matches draw on 5 verbs using a shared past-and-participle pattern with accepted spelling variants. Use the stored irregular class for the past tense: an -ed default or a lookalike from another class cannot establish the match; the dominant class is a shared past-and-participle pattern with accepted spelling variants (5 of 5), with 1 pattern class represented.
