Complete the sentence with the correct form of the verb in brackets: "The lab results ____ (come) through late on Thursday, long after the clinic had closed."

Erklärung

"Late on Thursday" marks a finished moment, so the sentence needs the past simple rather than a participle or a base form. This verb is irregular and takes no -ed ending, and leaving it unchanged would read as a present tense that contradicts the day named in the sentence.
