Match each base form to its past participle.

Explicación

The verbs in this past-participle set represent 1 verb using separate changes for past and participle, 1 verb using a participle that returns to the base pattern, and 4 verbs using one shared past-and-participle pattern. Participle matching depends on the verb's pattern class, while a form borrowed from a neighboring class is only a distractor; the dominant class is one shared past-and-participle pattern (4 of 6), with 3 pattern classes represented.
