The intern is trying to reassure their stressed boss. Select ALL the grammatically correct updates they could send.
The correct answers are "I finished the quarterly report two hours ago." and "I have already sent the presentation to the clients."
The word ago means the time period is finished, so it always pairs with the Past Simple ("I finished... two hours ago").
The word already connects a past action to the present moment without specifying exactly when it happened, which makes it perfect for the Present Perfect ("I have already sent..."). You cannot use yesterday with the Present Perfect!
