To accurately determine which inference can be made based on the passage, I would need to see the content of the passage itself. However, based on the options provided, if the passage discusses the impact of robots on employment, one might infer that "The author lost his job to a robot" or "More jobs are being created to make up for the jobs robots are doing," depending on the context.
If you can provide the passage, I can help you choose the most appropriate inference.
