To determine which innovation the photograph illustrates, it's important to analyze the subject of the photograph.
- If the photograph shows workers in a factory setting with machinery and a series of products moving along a conveyor belt, it likely represents the Assembly line.
- If the photograph depicts steel production or large furnaces, it would correspond to the Bessemer process.
- If it shows a gathering of workers engaged in protest or demonstration, it indicates a Labor strike.
Without seeing the photo, I can't give a definitive answer, but you can use these descriptions to match the photograph to the correct innovation.
