  "origin_caption": "A double-decker bus is parked on a city street, and a Coca-Cola ad is displayed on the side. There are several people on the street, including a man in the front of the bus and others walking or standing around. The bus is parked near a building, and a car is parked further down the street. The scene also includes a traffic light and a fire hydrant. A sign is visible in the background, and a backpack is placed on the ground near the center of the image. The image is dated 2015.",
  "thinking": "To make the question more difficult, we can change the year of the relaunch from 2015 to a more distant year. For example, we can change it to 1985, which was the original year of the Coca-Cola New Coke formula. We can also add more specific details about the ad or the people in the image, such as the brand of the car or the color of the fire hydrant. Additionally, we can modify the sign or the backpack to make them more prominent or unique to the scene.",
