Complete the sentence with the correct form of the verb in brackets. Report a completed result in an open time frame: The current shift is still under way, and the caretaker ___ the entire lobby; the inspection confirms that the whole task is complete. (wash)
پاسخ درست
has washed
توضیح
Has washed is required because the action has a visible present result within a shift that is still open. Washed would place it in a closed past narrative and weaken the stated connection to now.
