The bakery ____ its last loaf just after five o'clock yesterday.

Erklärung

Yesterday marks a completed event, so the verb goes into the past simple, and sell shifts to sold. Nothing further is needed for the perfect either: the bakery has sold out today uses the identical form, which is what makes this group easier than verbs with three shapes. Selled never occurs in English, and the base form leaves the sentence with no tense.
