PortMindBuild the answer key.
You label what you can see. We compare model answers with reviewed labels when we test a benchmark version.
Two questions for each image
1. Can you see at least one truck?
2. Is any truck carrying a shipping container or towing an empty chassis?
- Scan the whole image. Look left to right. There may be more than one truck.
- Look closer when needed. Zoom, drag and adjust brightness. Use Fit image to see the whole scene again.
- Answer both questions. One qualifying truck anywhere in the image is enough for Yes. You do not need to count trucks or judge whether they are moving.
Illustrated examples. These are not images from your review packet.
Pickup truck
Truck: Yes · Container / chassis: NoPickups count as trucks. An ordinary pickup is not container transport.
Truck with container
Truck: Yes · Container / chassis: YesLook for a shipping container physically connected to the truck.
Truck with empty chassis
Truck: Yes · Container / chassis: YesA chassis is the wheeled frame used to carry a container. It counts when attached to a truck, even when empty.
Container without a truck
Truck: No · Container / chassis: NoA container standing alone or on a train does not count. Neither does an unattached chassis.
When to choose Unsure
Choose Unsure if a relevant object or connection is too small, dark or hidden to identify reliably, even after looking closer. No means you can confidently rule it out. Do not infer an attachment just because a container is nearby.
If you can clearly see a truck but cannot judge its attachment, answer Yes to question 1 and Unsure to question 2. If there are clearly no trucks, both answers are No.
Brightness and contrast are viewing aids. They cannot recover detail the camera did not capture. Compare with Show original when needed. An optional note can explain what made an image difficult.
