Passage: This Morning I was alone in my house . I was at upstairs bedroom . I was reading news paper . Suddenly , I heard a doorbell . I was not sure who it was . I went down the stairs . Then I went towards the door . It is very important to check who is outside before opening the door . What I saw through the door hole was that It was courier delivery guy . He seemed authentic . So I unlocked the door and rotated the door knob to open the door . This is done to make sure the correct person for whom the parcel was intended only gets it . So I signed the paper , took the parcel . The courier guy smiled at me , I said bye to him and then I closed the door and locked it again . Question: What did they need to sign for before receiving? Option1: The check Option2: The paper
The paper
