Stuck? An answer is here.
1. A person is delivering papers.
2. She goes to the first two houses on the left, then to the third and fourth houses on the right and crosses towards the fourth house on the left.
3. A dog frightens her before she gets to the house, and she turns and runs down the middle of the street.
4. The person gets to the middle of the block, the dog gives up the chase and returns to his house.
5. The newspaper carrier walks away down the sidewalk.
(Note: The spacing of the feet give an indication of how fast the dog and person were running at each point. Also note that it is unlikely that this is a mailman, as the steps don’t go to each house.)
