Explanation
The context of the passage discusses the idea that certain surveys or experiments cannot be repeated in the same way once data is collected, making it impossible to verify specific details later. The term "reproducible" fits this idea because it refers to something that can be repeated or recreated. In the context of scientific studies or surveys, reproducibility means that the same experiment or survey can be conducted again under the same conditions to check for consistency in results.
