Final answer:
George's comment to Sarah shows he is focusing on an artificial social barrier by linking Gene's recommendation and business acumen to his background.
Step-by-step explanation:
The comment made by George suggests that he is focusing on an artificial social barrier by attributing Gene's recommendation to his background and implying people from such a background lack the savvy to understand the business world. This not only creates an unnecessary division but also relies on stereotyping and prejudicial assumptions. Furthermore, it disregards the potential value of different perspectives and the importance of inclusivity in the workplace. The notion that a certain background predetermines one's business acumen is a baseless stereotype that can lead to discrimination and does not consider individual competencies and experiences.
