Passage OneQuestions 52 to 56 are based on the following passage.Amid all the job losses, there’s no category of worker that the economic disruption has been good for: nonhumans.From self-service checkout lines at supermarket to industrial robots armed with saws and taught to carve up animal bodies in slaughter-houses, these ever-more-intelligent machines are now not just assisting workers but actually kicking them out of their jobs.Automation isn’t just affecting factory workers, either.
