did robots help make your pizza?\nhow does the author use expert opinion to add credibility to the article?\nby quoting a professor who explains the challenges of automation\nby sharing opinions from random restaurant customers\nby describing a fictional robot pizza maker\nby focusing only on the founders success stories
Answer
Brief Explanations:
Expert opinions are authoritative. A professor explaining automation challenges is an expert in a relevant field (like technology or business related to automation). Random restaurant customers are not experts. A fictional robot pizza - maker is not real - world expertise. Focusing only on founders' success stories is not using an external expert opinion.
Answer:
By quoting a professor who explains the challenges of automation.
