Read about Colin. Choose the correct option as per the situation/timing asked further:
Colin goes to work every day. He leaves home at 8 o'clock and arrives at work at about 8:45. He starts work immediately and continues until 12:30 when he has lunch (which takes about half an hour). He starts work again at 1:15 and goes home at exactly 4:30. Every day he follows the same routine and tomorrow will be no exception.
